Pdf Editor Pro on Windows

The same PDF editor as on the Mac, on your PC: the same engine reading and writing the file, the same five sections at the top, the same menus and palettes. A document starts on one computer and finishes on the other. Download, unzip and run — nothing to install, and no in-app purchases.

One app, two computersA PDF you annotate, edit or sign on the Mac opens on Windows exactly as you left it — the same code reads and writes the bytes.
Nothing to relearnSame five sections, same tools, same palettes, same menu bar. Every ⌘ is Ctrl and every ⌥ is Alt.
Free and portableNo installer, no runtime to add, no in-app purchases: unzip it anywhere, run it, delete the folder when you want it gone.
What it does

Everything the Mac app does

Open a PDF and mark it up, edit the real text and the real page objects, fill in and sign forms, organise the pages, redact, OCR a scan, and hand it on.

AnnotateHighlight, underline and strike out that follow the words rather than a rectangle drawn near them; pencil and smoothed pen; rectangle, ellipse and line; text boxes in any font installed on the PC, embedded into the file; sticky notes with their bubbles; sound notes recorded from any microphone; Approved, Draft, Confidential and custom stamps; and an eraser that lights up the mark it is about to remove.
EditRewrite printed page text — type into it, change its typeface, size and colour — move and resize the page’s own objects, reorder them, recolour a solid fill, place an image, and draw links that go to a page or a web address.
Fill & SignThe Fill arrow lights the field under the pointer; Tab walks the document’s own order and Space ticks a box. Signatures are drawn, typed, taken from a photo of paper or from the webcam, kept in a library with initials and signer profiles, and dropped fitted to the space the form left for them — or placed on every signing spot in turn. File › Digitally Sign… signs with a real certificate from the Windows certificate store, and every signed document is checked when you open it.
PagesReorder by dragging, duplicate, rotate, crop with a live preview, extract to a new PDF, merge another PDF in. Bates numbers, headers and footers, watermarks in three placements, and a bookmark tree you can edit.
Redaction & OCRTwo-stage redaction that really removes the text from the file, and text recognition that lays a searchable layer over a scan without touching the picture.
ExportPDF, PDF with compression (with the size and a before/after preview measured before anything is written), PNG, JPEG, TIFF, Word (.docx), print, and Share.
AI and MCPThe AI Console palette, and a built-in MCP server so Claude Desktop, Claude Code, Codex or VS Code can drive the document with the same machinery the buttons use.
Differences from the Mac

Where Windows is not macOS

A handful of things macOS does for the Mac app, Windows does differently or not at all. None of them is hidden: where a command cannot run here it stays in its menu, greyed, with the reason in its tooltip.

Text recognitionOCR uses the Windows OCR engine (Windows.Media.Ocr) instead of Apple Vision, so the languages it can read are the ones installed on your PC (Settings › Time & language › Language). The rest is the same: pages that already have real text are skipped and counted, and the picture is never touched.
EPS and PostScriptDo not open, and cannot be placed on a page. The command is there and says so: the only PostScript interpreter that could be shipped is licensed in a way we will not ship.
RTF and RTFDDo not open. Word documents (.docx) do — read by our own parser and laid out with DirectWrite, so a table arrives as paragraphs in sequence rather than a table, and the app says so when it opens one.
Photographing a signatureThe Mac offers Import from iPhone or iPad › Take Photo. Windows has no such handover, so the same place in the Signatures palette offers Take Photo… from the PC’s webcam instead, and the shot lands in exactly the same paper-to-ink cleanup. With no camera attached the item is greyed with the reason.
Typed signaturesType Signature offers the handwriting faces installed on Windows rather than the ones that ship with a Mac. Present on a plain Windows 11: Gabriola, Segoe Script, Segoe Print, Ink Free. Nine more — Edwardian Script ITC, Palace Script MT, Kunstler Script, Vladimir Script, Monotype Corsiva, Brush Script MT, Lucida Handwriting, Freestyle Script, Mistral — appear as soon as Microsoft Office installs them. A face that is not installed is never offered.
PrintingGoes through XPS as real vectors — paths and glyphs, not a picture of the page — with a raster fallback at the printer’s own resolution when the vector path is refused. When it falls back it tells you; it never degrades in silence.
ShareUses the Windows Share contract, so the same picker other Windows apps use. It shares the saved PDF, or a PNG of the current page.
Digital signingIdentities come from the Windows certificate store (Personal) rather than the macOS keychain, and the app can create a self-signed ID on the spot, exactly as on the Mac. Every phrase that said «keychain» says «certificate store», and every «this Mac» says «this PC».
MCP serverSpeaks both stdio and HTTP on the loopback address (port 8722 by default) and publishes 33 of the Mac’s 34 tools. The missing one is compare_page, which compares our rendering with Apple’s — there is no such referee on Windows, and asking for it by name gets that answer rather than a wrong picture. As on the Mac, the MCP server works on its own document, not on the one in your window.
AI ConsoleThe same four engines as the Mac. The transcript is drawn by the app itself rather than by a web view, so it keeps markdown, links and scrolling but you cannot drag-select the text out of it (copy the message instead). Your API key is encrypted with Windows DPAPI rather than kept in the clear. Gemini answers an invalid key with HTTP 400, so that is the code you will see quoted back at you.
AppleScriptNot here. The MCP server covers the same surface, from any assistant that speaks it.
Word exportLaid out with the same text engine the canvas draws with (DirectWrite and HarfBuzz) rather than TextKit, so line spacing is computed from the font’s own metrics and a font Word already has (Calibri, Cambria, Consolas) is passed through instead of being remapped.
TIFF exportOne file per page, as on the Mac — never a single multi-page TIFF.
Dropping a signature imageA file dragged from Explorer onto the Signatures palette is added to the library. An image dragged out of another application — with no file behind it — is not: Windows hands a drop over as file paths.
Feedback buttonThe 💬 button on the canvas opens the Feedback palette; on the Mac you can also drop a file on the button itself. Here you attach it inside the palette, with the paperclip.
Dropping a file on the pageA file dropped on the window opens as a document rather than being placed on the current page — and several images dropped together become one document, one page each, in name order. To put a picture on the page you are looking at, use File › Place….
PastingCtrl+V brings in objects you copied inside this application. Artwork pasted from another program is refused with the reason rather than arriving wrong; copying page text to the clipboard works as it does on the Mac.
Form radio buttonsSpace ticks the checkbox under the keyboard focus, as it does on the Mac. On a group of radio buttons it moves the focus rather than choosing the option: click the one you want, or use the Fill arrow.
One document at a timeThis build shows one document in one window. It still remembers the section and the tool you last used — but per launch rather than per window.
KeyboardEvery ⌘ is Ctrl and every ⌥ is Alt. Three chords have no Windows image and are deliberately left off rather than guessed: Export with Compression… and Export Word (.docx)… (the Mac uses Control together with Command, which is the same key here) and Paste In Front (whose Mac chord is Ctrl+F, which on Windows is Find). All three are one click away in their menus. The complete list is on the shortcuts page.
Not yet

Greyed, not hidden

The menu bar is the Mac’s, item for item. A command this build cannot run yet sits in its place, greyed, so you can always see the shape of the whole application — and so can we.

Rendering comparisonView › Rendering Test… and Automatic Rendering Test appear when you switch on the developer tools in Options › Debug, and stay greyed: they compare our drawing against Apple’s renderer, which does not exist here.
Diagnostic log fileSend Logs Now and Reveal Log File in Options › Debug are greyed with the reason: this build keeps no session log. Crash reports are still collected and offered at the next launch.
Object grouping and lockingObject › Group, Ungroup, Lock and Unlock All are in the menu and greyed, exactly as on a PDF on the Mac: a finished page has no groups to make.
Assign Profile…Greyed here because it is greyed on the Mac too — it is the app’s one permanent stub, and it is kept so the two menu bars match line for line.
Palettes that come to youThe Text palette does not yet come forward on its own when you select text or draw a text box, and the Edit palette does not yet park itself beside what you selected. Open them from the Window menu (Text is Ctrl+T).
Two small page and bookmark gesturesThe Pages sidebar has no right-click menu yet — the same commands are in the Pages palette’s ≡▾ menu — and a bookmark cannot yet be pointed at a new destination.
Combo boxes and spinners in the darkIn the dark theme a drop-down keeps a light arrow button, and so does a number spinner: the field and its text follow the theme, that little button is drawn by Windows itself.

Closed in the last pass, and now live: the zoom percentage at the bottom is an editable field with its ten presets and Fit On Screen; the page number beside it is editable too; clicking the signature badge opens the verdict on each signature; Layout › Go to Page… asks for a page number and refuses one outside the document instead of silently clamping it; and Place Image… and Add Stamp in the top bar are wired.

And the things the Mac app deliberately does not do, this one does not do either, for the same reasons: no password protection or encryption, no adding or deleting pages (reorder, rotate, duplicate, extract and merge, yes), no reshaping page objects point by point, no gradients or patterns on page objects, no re-flowing of printed text, and no SVG export.

Specifications

What is in the box

Version 26.5.2, build 1. Everything below is in the download.

RequirementsWindows 11, x64 or ARM64. Both architectures are native builds — the ARM64 one is not emulated.
DownloadA single .zip. No installer: unzip it anywhere and run pdfeditor.exe.
Or an installed copyThe same build is also packaged as PdfEditorPro-26.5.2-<arch>.msix, with PdfEditorPro.appinstaller beside it for automatic updates. Install either one if you would rather have Pdf Editor Pro in the Start menu and registered for .pdf files.
Nothing else to installNo frameworks, no redistributables: the zip is everything.
SigningSigned by Rainbowfactory Ltd with an Azure Trusted Signing certificate and timestamped, so Windows opens it without a SmartScreen warning.
Same engine as the MacThe parser, the interpreter, the incremental-update writer and the renderer are the Mac app’s own code, compiled for Windows. The two applications agree on the same file.
SavingYour changes are written onto the end of the original file: the bytes you started from stay untouched, a document you did not edit is byte-for-byte the file you opened, and an existing digital signature survives a Save. Save As and Export rebuild the file, and the app says so before it breaks one.
OpensPDF, and as a page you can view, annotate and export: PNG, JPEG, TIFF, GIF, BMP, HEIC/HEIF (best effort, through the codec Windows has installed), Photoshop (PSD, composite), SVG, Adobe Illustrator (AI) and Word (DOCX).
FontsUses the fonts installed on your PC, through DirectWrite. A font a document does not carry is substituted and the status bar says how many — it never pretends.
ColourRGB, CMYK, greyscale and named spot inks with their tints. A document opens in the colour mode it was made in, the Swatches palette offers colours in that system, and the Separations palette previews the real printing plates one at a time.
CanvasDrawn on Direct3D 12, with an automatic fallback to CPU rendering when no device is available — the same shape as Metal and its fallback on the Mac.
MenusThe Mac menu bar, item for item, in seven menus (the macOS application menu does not exist on Windows, so About, Check for Updates…, Preferences… and Quit move to Help, Edit and File). A command the shell cannot run yet is greyed in its place, never hidden.
PalettesAll thirteen: Swatches, Text, Info, Pages, Separations, Bookmarks, Annotations, Signatures, Edit, Tags, Document Info, AI Console and Feedback, plus Performance behind the developer switch. Tab hides them all; each remembers where you left it.
MCP serverRun pdfeditor.exe --mcp-stdio, or switch on Allow external control in Options › MCP Server for the HTTP transport on 127.0.0.1:8722. The configuration to paste into your assistant is on that panel. The listener answers on the loopback address only.
FeedbackWindow › Feedback (Ctrl+Alt+F), the 💬 button on the canvas, or Help › Send Feedback…: text and screenshots go to the same tracker the Mac app reports to, queued on disk when you are offline.
UpdatesThe direct download keeps itself up to date: it checks in the background, downloads the signed package, verifies the signature and installs it when you press the button. Help › Check for Updates… checks right away. Nothing unsigned is ever installed.
HelpPdf Editor Pro Help (F1), built from the app’s own menus and tools so it cannot go out of date, and Keyboard Shortcuts… with the full list.
PrivacyFree, with no in-app purchases and no account. Your documents are never uploaded. Nothing leaves the PC unless you send it: feedback you write, a crash report you agree to send, or a request you make of an AI engine — and on a PDF the AI request does not carry the document. There is no usage analytics of any kind in this version. The whole story, read from the code, is on the privacy page.
ShortcutsEvery ⌘ became Ctrl and every ⌥ became Alt, item for item. The full list, menu by menu, is on the shortcuts page, and inside the app under Edit › Keyboard Shortcuts….
Microsoft Store

Coming to the Store

The Store copy of Pdf Editor Pro is on its way — the same application, installed and updated by the Store, with no zip to unpack. Until it is there, the download on this page is the way to get it, and it updates itself. Progress lands on Discord and in the changelog.
