Privacy & security
How privacy works here.
- Inside your browser tab. JavaScript and WebAssembly read your file from local memory, perform the requested operation, and offer the result as a download. No upload happens.
Using the tools
Day-to-day use.
- No. Every browser-based tool works without sign-up.
Account & billing
No accounts, no surprises.
- Every tool on the site is free to use without a card or account. The free tier is ad-supported. A Pro tier (coming soon) removes ads and adds heavier features.
Troubleshooting
When something feels off.
- Large files take longer because all processing is local. A 100 MB PDF can take 10–30 seconds on a typical laptop. Mobile devices may be slower. Close other heavy tabs if it stalls.
