Free PDF Tools Online
Merge, split, compress, convert and protect PDF files without installing anything.
Working with PDFs usually means either paying for desktop software or uploading private documents to a stranger's server. Neither is much fun when all you want to do is shrink a file so it fits in an email. Every PDF tool on this page runs entirely inside your browser, which means your contracts, invoices, CVs and scanned records never leave your device. There is nothing to install, no account to create, and no watermark stamped across your output.
What you can do with these PDF tools
The collection covers the jobs people actually need day to day rather than a long list of features nobody uses. Whether you are preparing an application, sending a report, or cleaning up a scanned document, there is a tool here for it.
- Combine several PDFs into one file, in the order you choose.
- Split a large document or pull out just the pages you need.
- Compress a heavy PDF so it fits under an upload or email size limit.
- Convert between PDF and images, Word-style text, and other formats.
- Rotate, reorder or delete pages that came out wrong from a scanner.
- Add a password, a watermark, page numbers or a signature.
Why in-browser PDF editing is safer
Most free PDF websites work by uploading your file to their server, processing it there, and sending it back. That is fine for a shopping list and genuinely risky for anything with a name, an address, a bank detail or a signature on it. Our tools use JavaScript running on your own machine, so the file is opened, changed and saved without a single byte travelling over the internet. You can even disconnect your Wi-Fi after the page loads and most tools will still work.
Tips for getting the best results
- If a PDF is too big, compression almost always helps more than splitting it, because images are usually the cause.
- Merging first and compressing second gives a smaller final file than doing it the other way around.
- Scanned pages are images, so use the OCR tool if you need to select or search the text inside them.
- Keep the original file until you have opened the result and checked it looks right.
