Frequently Asked Questions
Is One PDF Editor really free?
Yes! All tools available on One PDF Editor are completely free to use. There are no hidden subscription
fees, watermarks automatically added to your documents, or page limits on our standard tools.
Are my files uploaded to your servers?
It depends on the tool you use. Essential tools like Split, Merge, and Images to PDF run directly in your
web browser utilizing WebAssembly. This means your files never leave your device.
For more advanced tools that require server-side computing, your files are securely uploaded via encrypted
connections. However, we have a strict zero-retention policy: all files are permanently deleted from
our servers automatically within 1 hour after processing.
Can I use this on my mobile phone?
Our website is fully responsive and many of our tools like Compression, Splitting, and Merging will work on
modern mobile browsers. However, for complex text editing and digital signatures, we recommend using a
desktop browser for the best experience.
What is the maximum file size limit?
Because processing happens locally in your browser, the only limit is your computer's available memory. Most
modern devices can easily handle standard PDFs up to 50MB directly in the browser without any issues.
