Merge, Split, Compress, Sign PDFs entirely offline. Zero uploads, zero limits. Stapler is a complete PDF toolkit that never leaves your browser — no uploads, no accounts, no server, ever. Most "free PDF tools" online quietly send your file to a server you'll never see, then ask you to sign up to get it back. Stapler works differently: every merge, every redaction, every signature is computed on your own machine, inside a sandboxed offline-only extension page. Your documents never touch a network — not ours, not anyone's. Organize & edit — Merge, split, and extract pages. Rotate, delete, duplicate, and reorder. Crop, insert, and remove blank pages. Normalize mixed page sizes. Build N-up layouts and booklets. Add bookmarks, page numbers, watermarks, Bates stamps, and QR/barcode stamps. Convert — Images (PNG/JPEG/HEIC) to PDF and back. PDF to plain text or Markdown. Markdown to PDF. Extract embedded images and tables. Sign & fill — Draw, type, or import a signature. Fill and flatten interactive form (AcroForm) fields. Protect & clean up — Real redaction: the underlying content is structurally removed from the file, not just painted over, with a verification pass before you save. Scrub metadata. Straighten, deskew, and clean up phone-camera scans of paper documents. Compress — Shrink file size with a raster pass or a surgical re-encode that keeps text sharp — and never inflates a file that's already optimized. Review & manage — Annotate with highlights, freehand marks, sticky notes, and whiteout. Compare two documents side by side. Batch-process a whole folder with a saved recipe. Built for real accessibility, too: every tool is fully operable from the keyboard alone, in ten languages including right-to-left scripts, in light or dark mode. Privacy, proven — not promised Zero network requests at runtime. Verify it yourself: open DevTools' Network tab and use any tool — nothing appears. Zero permissions in the install prompt. Chrome won't even show you a warning, because there's nothing to warn about. No accounts, no tracking, no analytics, no watermarks, no file-size limits, no daily quota. Open source under the MIT licence — read every line of the code that touches your files. We built the tool we wanted for our own sensitive documents: something that just works, and never has to ask where your files are going — because they aren't going anywhere.
