PdfCraft is an open-source PDF workbench written in Rust, running here in a browser tab. Reorder and rotate pages, merge and split files, fill and sign forms, add comments. Your documents never leave your computer.
Most online PDF tools upload your file to a server and hand it back. PdfCraft compiles a full PDF engine to WebAssembly, so the same work happens in your browser. Press Ctrl/⌘+K to find any tool by name.
Organize pages shows every page at once. Select with click, Ctrl/⌘-click or Shift-click, then rotate, delete, duplicate, insert blank pages or pages from another file, and move them earlier or later. Every change can be undone before you save.

Combine files merges any number of PDFs, each with its own bookmark and its bookmarks nested underneath. Extract copies chosen pages into a new document; Split cuts every n pages or before the pages you pick. Links, form fields, layers and attachments come along.

Interactive fields are highlighted and listed with their values. For a flat form, Fill & Sign types text onto the page, adds checkmarks, crosses and today’s date, and places your signature or initials: drawn, typed or from an image.

Sticky notes, highlights, underlines, text boxes, shapes, freehand ink, callouts and stamps, shown as threaded conversations in the Comments panel. Layers in the PDF switch on and off and the page redraws at once.

PdfCraft implements the PDF standard security handler, from 40-bit RC4 to AES-256, with user and owner passwords. Restricted documents show a notice and their permissions are honoured. Protect a PDF with your own password, edit its title and author, or redact text.

Requests go from your browser to the provider. We never see your key, your document or the answers, and we add no markup.
How Chat with PDF worksThe editor is the official web build, byte for byte. Around it we add a few things the bare build doesn’t have.
Each new PdfCraft release is checked against its published SHA-256 checksum and deployed here. You are on v0.6.0.
Summaries, answers, tables and translations from OpenAI, Gemini or OpenRouter models, straight from the browser.
File › Save downloads your PDF as usual, and the top bar warns you while there are unsaved changes.
No account, no watermark, no upload. Close the tab and nothing of yours is left on a server.
PdfCraft is in alpha. Expect rough edges, keep the original file, and save before closing the tab: the browser version has no autosave.
Yes. The editor is free and open source, there is no account, no watermark and no page or file limit set by us. The optional Chat with PDF panel uses your own AI provider key, so any AI usage is billed by your provider, not by us.
No. PdfCraft runs inside your browser with WebAssembly. Opening, editing and saving happen on your device: files open from your disk and save back as downloads. The only exception is the Chat with PDF panel, which sends the PDF you pick straight to the AI provider whose key you entered.
Partly. PdfCraft has an Edit text & images tool, but its developers list reliable editing of existing text as still thin, especially for Chinese, Japanese, Korean and right-to-left scripts. Adding text, comments, form entries and Fill & Sign text works well today.
Not in the browser. The web build has no autosave or crash recovery, so save with File › Save (Ctrl/⌘+S), which downloads the PDF, before you close the tab. The browser asks before you leave a page with unsaved changes. The desktop app autosaves every minute.
In the browser, Print saves a print-ready PDF copy that you then print from your usual PDF viewer. Printing straight to a printer works in the macOS, Linux and FreeBSD desktop apps.
Not in the web build. Fill & Sign places a visible drawn, typed or image signature, which is what most forms ask for. Digital signatures with a certificate (PKCS #12) need the desktop app.
A current Chrome, Edge, Firefox or Safari on a desktop or laptop. The interface is built for a mouse and a large screen; it runs on tablets and phones, but panels are cramped.
Not yet, and its developers say so. PdfCraft is an independent, clean-room project in alpha. By their own count it covers about 55% of everyday Acrobat work (viewing, commenting, filling and signing forms, organizing pages); Office conversion and OCR beyond Latin script are still weak.
