Free PDF Tools Online
A complete set of free PDF tools for everything you need to do with a document — compress a PDF for email, merge several files into one, split out the pages you want, convert to and from Word and images, unlock a password-protected file, rotate pages, add page numbers or watermarks, and pull text out of scans with OCR. Unlike Smallpdf and iLovePDF, there are no daily limits and no watermark on your output. Everything runs privately in your browser using WebAssembly, so your documents are never uploaded to any server and stay completely on your device.
Compress & optimise
Get a PDF under an upload limit without turning the text to mush.
Know the limit you need to hit? Go straight to 100KB, 200KB, 500KB, 1MB, 50KB, 300KB or 2MB.
Organise pages
Combine, separate and reorder documents — merge several files into one, pull out a page range, or drop the pages you do not need.
Convert to and from PDF
Move between PDF, Word and images in both directions, keeping the formatting intact.
Sign, fill & mark up
Complete and return a document without printing it — type into form fields, drop in a signature, or stamp a watermark.
Passwords & security
Encrypt a document before sending it, or remove a password you already know from a file you own.
Extract text from scans
Turn a scanned or photographed document into text you can search, copy and edit.

Getting a PDF under a portal’s upload limit
Almost every PDF that needs compressing is going somewhere specific — a visa application, a bank KYC upload, a court e-filing system, an email that keeps bouncing. Each of those enforces its own ceiling, which is why the compressor lets you set an exact target rather than offering a vague “high / medium / low” choice.
One thing worth knowing before you compress: most of a large PDF’s weight is images, not text. A scanned document is really a stack of photographs, so it compresses dramatically. A text-only PDF exported from Word is already small and has little left to give — if that file is over a limit, the pages are usually the problem, and splitting out the ones you actually need will do more than compression.
We keep a walkthrough for each of the common cases, with the specific limit each one enforces:
