About PDFStaple

Last updated 21 August 2026. This page is available in English only.

What this is

PDFStaple does the boring, necessary things people need to do to PDF files: merge them, split them, rotate a sideways scan, get one under a file-size limit, convert to and from Word and Excel, OCR a photocopy, fill a form, redact a name. There are 42 of them and they all work the same way — drop a file in, get a file out.

Every tool is free and complete. There is no trial that expires, no daily task cap, no watermark on the output, and no point at which the thing you were doing stops and asks for an email address. We think the tools people reach for once a year, in a hurry, under a deadline, should just work.

How it handles your files

7 of the tools never upload anything at all — they run inside your browser tab, so the file never leaves your computer. The rest need a real document engine that cannot run in a browser, so the file is sent over HTTPS, processed, and then deleted two hours later, along with the result.

The result screen always tells you which of the two happened, so you never have to guess. There are no accounts, no analytics services, no advertising trackers, and no third-party scripts on any page — even the fonts are served from our own domain rather than fetched from Google. The full detail is on the privacy page, and the rules for using the service are in the terms of service.

Built on open engines

We did not reinvent PDF parsing, and you should be suspicious of anyone who claims they did. The heavy lifting is done by mature open source projects — qpdf and pikepdf for structural work, Ghostscript for compression and PDF/A, LibreOffice for Office formats, Tesseract for OCR, Chromium for HTML rendering, and pdf-lib for the tools that run in your browser. What we built is the part around them: a fast, quiet interface that does not get in the way.

Available in 27 languages

The interface is translated into 27 languages, including Arabic, Persian, Filipino, Vietnamese, Thai, Ukrainian and Hindi, with right-to-left layout where it belongs. A tool you need once, urgently, is exactly the kind of thing that should not also demand you read English.

For libraries, schools, and public-service sites

If you maintain a help page, research guide, or patron handout that points people to a PDF tool, a few things about PDFStaple may be relevant:

• No account is ever required, which matters on shared or public computers where patrons cannot or should not create one.
• No daily limit and no upgrade prompt, so step-by-step instructions you write today keep working.
• Many common tasks — merging, splitting, extracting pages — never transmit the document anywhere, which is worth knowing when the documents in question are transcripts, medical records, or filings.
• Compress PDF takes a target size directly, so “must be under 25 MB” is one field rather than trial and error.
• PDF/A conversion is available free, which thesis and archival submission workflows often need.
• The interface is available in 27 languages at the same URL structure.

You are welcome to link to any tool page directly, and to reproduce instructions for using it in your own handouts without asking us. If something is missing or wrong for your use case, write to [email protected] — we read it.
