About PDF Tools
PDF is the closest thing to a universal document format — it looks the same on every device, prints predictably, and locks formatting in place. But that same rigidity makes routine tasks like combining files, removing a page, or shrinking a file size feel harder than they should be. This collection covers the full range of everyday PDF work — merging, splitting, compressing, rotating, watermarking, password protection, OCR, signing, and form filling — with every tool running directly in your browser using a real PDF engine, not a simplified approximation. Nothing you upload here is sent to a server.
Why use these tools
- Every tool reads and writes real PDF structure, so fonts, tables, and page geometry come through exactly as they were, not flattened or approximated.
- Password protection and unlocking use standards-compliant encryption that works in any PDF reader, not just this site.
- OCR runs a genuine open-source engine (Tesseract) on-device, so scanned documents become searchable without your file ever leaving your computer.
- No file size caps, watermarks, or account requirements on any tool.
Frequently asked questions
Do I need to install anything to edit a PDF here?
No — every PDF tool runs directly in your browser tab using JavaScript and WebAssembly. There's nothing to install, and it works the same way on Windows, Mac, Linux, or a tablet.
Are my PDFs uploaded to a server when I use these tools?
No. All processing — merging, compressing, editing, OCR — happens locally on your device. Your files are never transmitted anywhere, which is also why these tools keep working without an internet connection once the page has loaded.
Can I use these tools on a phone or tablet, or only a desktop computer?
The tools work on any modern browser, including mobile. Complex page-editing tasks are naturally easier with a larger screen, but nothing here requires a desktop specifically.
Which PDF tool should I use to make a scanned document searchable?
OCR PDF adds an invisible, searchable text layer over a scanned document's images using on-device optical character recognition, without altering how the page looks.
Is there a limit on how many PDFs I can process, or how large they can be?
No artificial limits are imposed by these tools. The only real constraint is your own device's available memory, since everything runs client-side rather than on a shared server with usage quotas.
