Safety & privacy
The editor runs entirely in your browser via JavaScript and WebAssembly. Your PDF is opened, edited and re-exported on your device — no server uploads, no cloud storage, no logs. You can even go offline after loading the page and every feature keeps working. That matters most when handling contracts and confidential files.

KitsyApp is 100% free — no signup, no document limits, and no watermarks stamped on your files. You get the full editing toolkit that paid services sell as monthly subscriptions, plus a unique advantage: your documents never leave your machine.
Frequently asked questions
Will editing change the original formatting?
No. The editor works on the PDF structure directly: existing text, images, fonts and layout stay intact — you only add or modify content layers on top.
Is a signature added this way legally valid?
Image signatures (drawn or uploaded) are widely accepted in everyday civil transactions. For transactions requiring certified digital signatures, you need a certificate-based digital signature from a licensed provider.
Do I need to install anything or create an account?
No. Open the page and start editing in your browser, on desktop or mobile. No software downloads, no accounts, no document limits.
Can I edit text labels in technical PDF drawings?
Yes — a distinctive KitsyApp strength. The editor detects text blocks in drawings and lets you relabel them without breaking the vector geometry of lines and dimensions.
