Search for "free PDF tools" and you will find hundreds of options. Most of them do the same handful of things. Rather than listing everything that exists, here are the five tools that solve the problems people actually run into — the ones worth bookmarking.
1. PDF Compressor
File size is the most common PDF problem. Emails bounce, uploads fail, and storage fills up — all because PDFs are larger than they need to be. A good compressor reduces file size by optimizing images and stripping hidden data, usually without any visible quality loss. Our compress PDF tool runs entirely in your browser, so your file never leaves your device. For most documents, it cuts size by 40–70% in under 10 seconds.
2. PDF Merger
Combining multiple PDFs into one is something most people need to do regularly — assembling a report from separate sections, packaging documents for a client, or combining scanned pages. The merge tool lets you upload multiple files, arrange them in order, and download a single combined PDF. It handles any number of files and preserves the quality of every page. The whole process takes about a minute.
3. PDF Editor
A basic PDF editor covers the most common editing tasks: adding text, inserting images, and rearranging pages. You do not need Adobe Acrobat for any of these. The online PDF editor lets you open a file, make changes, and download the result — all in your browser. It is the right tool when you need to annotate a document, fill in a form, or make a quick correction before sending.
4. PDF Splitter
When you only need part of a document, splitting is faster than recreating it. The split tool lets you select specific pages and extract them as a new PDF. This is useful for pulling out a single contract from a larger archive, extracting a chapter from a report, or separating pages that need to go to different recipients. Select the pages, download the result — done.
5. PDF Unlocker
Password-protected PDFs are common, and the restrictions they impose — blocking printing, copying, or editing — can be genuinely inconvenient when you own the document. The unlock tool removes password protection from PDFs you have the credentials for. Enter the password, download the unlocked file, and use it freely. It works on both user passwords and permissions restrictions.
These five tools handle the overwhelming majority of PDF tasks that come up in everyday work. They are all free, all browser-based, and all process files locally — so your documents stay private. No account needed for any of them.
