PDF Tools — 23 Free Online Tools
Merge, split, compress, sign, redact and convert PDF files without ever uploading them. Browser-based processing means your documents never leave your device.
PDF is a container format rather than a document format, which is why so many editors mangle it. These tools work on the page structure instead: the PDF Merger and PDF Splitter operate at page granularity, the PDF Redactor is built to remove content rather than draw a box over it, and the PDF Accessibility Checker reports the PDF/UA and WCAG problems that make a file unusable with a screen reader.

Frequently Asked Questions
4 Q&AWhat PDF operations are supported?
There are 23 tools covering: merging multiple PDFs, splitting a PDF into pages, editing content, compressing size, converting to and from images, converting to and from Word and Excel, OCR on scanned PDFs, comparing two PDFs, redacting, watermarking, signing, page numbering, and unlocking password-protected PDFs.
Are my PDF files uploaded to a server?
No. All 23 PDF tools run in your browser using PDF.js, pdf-lib, and SheetJS. Your documents never leave your device. The "100% private, browser-based" promise is enforced by the client-side architecture.
How large a PDF can I process?
Browser memory is the limit. In practice PDFs up to about 100 MB work reliably for merge, split, and convert. Compression of large scanned PDFs may take a few seconds; very large files (500 MB+) may exhaust tab memory.
Are these PDF tools free for commercial use?
Yes. There is no signup, no watermark, no per-file fee, and no usage limit. You can use them for personal, business, or client work without restriction.
