How these PDF tools work
Every PDF tool on this page runs entirely inside your web browser using WebAssembly and the PDF-lib library. When you select a file, it is loaded into memory on your device and processed there — nothing is transmitted to a server. This means your documents stay private by design, not just by policy.
Most PDF operations complete in under a second for typical file sizes. Merging, splitting, compressing, rotating pages, adding passwords, and watermarking all happen client-side. For compression specifically, the tool removes redundant embedded resources and re-encodes images at a lower quality level while keeping the document readable. The result is a smaller file that opens normally in any PDF viewer.
Password protection uses AES-256 encryption, the same standard used by banks and government agencies. Once a password is set, the file cannot be opened or edited without it. The unlock tool works by verifying the password you supply and then producing an unencrypted copy — it does not brute-force anything and requires the correct password.
Frequently Asked Questions
- Are all 20 PDF tools free?
- Yes: no account, no watermarks on output, no file count limits. Every PDF tool here is genuinely free.
- Do my PDFs get sent to a server?
- No. AlteredIdea uses pdf-lib compiled to WebAssembly, so your file is processed inside your browser tab. Nothing is uploaded.
- Is there a file size limit?
- We don't set one. Your browser's memory is the practical ceiling. Most users handle files up to a few hundred MB without issues; very large files may slow things down a bit.
- Why does my laptop fan spin up when processing a big PDF?
- Because your CPU is doing the work instead of a remote server. That's intentional: it's the trade-off for keeping your files private. For large PDFs, expect a few seconds of heavy lifting.
- Can I use these tools on iPhone or Android?
- Yes. Safari on iPhone and Chrome on Android both work. You can upload from your Files app or Photos app. Some tools like the PDF editor are more comfortable on a bigger screen, but they all run on mobile.
- Can I process a password-protected PDF?
- Most tools need the file to be unlocked first. Use the Password Unlock tool (you'll need the current password), then run it through whatever else you need.
