PDF tools
📎Merge PDF
Combine multiple PDFs into one, in the order you choose.
✂️Split PDF
Extract pages or break a PDF into separate files.
🗜️Compress PDF
Shrink file size with a real compression engine (pdfcpu → WASM).
✏️Edit PDF
Retype any text, add new text, rotate and resize pages.
🏷️Watermark & Stamp
Add text or image watermarks and stamps — or remove them.
🔏Check Signatures
Validate a PDF's digital signature and inspect the evidence.
🔒Protect PDF
Encrypt a PDF with AES-256 — the password never leaves your device.
🔓Unlock PDF
Remove a password from a PDF you own, using the password you know.
Private by architecture
Processing runs in your browser via WebAssembly. There is no server to upload to — disconnect from the internet and the tools keep working.
No watermarks, ever
Your exported PDF contains your document and nothing else. No stamps, no branding, no "upgrade to remove".
Fast and free
No queues, no file limits tied to a paywall, no accounts. Your hardware does the work, so we don’t have to charge for servers.
Works offline
After your first visit, every tool runs without internet. Install localdobe as an app and use it on a plane.
