Frequently Asked Questions
Answers about privacy and on-device processing.
Are my files really safe?
Yes, completely. Unlike traditional cloud services, PaperFox never transmits your files to any remote server. All file parsing, manipulation, and generation occur strictly within your local web browser.
Is PaperFox free to use?
Yes. PaperFox is completely free, with no account, subscription or email address required. PaperFox does not add its own watermark to your documents. For technical limits, see “Is there a file size limit?”
Do I need to install any software?
No installation is required. PaperFox runs in modern desktop and mobile browsers, functioning like a fast local application without downloading native software.
Does it work without an internet connection?
An internet connection is needed to load the site and required tool files. File processing takes place on your device; full offline use is not yet supported.
Is there a file size limit?
Yes. Each operation supports up to 75 MB and 150 pages. When selecting multiple files, the combined size is counted. Available memory, especially on mobile devices, may require smaller files.
Does it work on mobile devices?
Yes. You can use modern mobile browsers. A computer may be more comfortable for large files and detailed PDF editing; performance depends on your device memory and browser.
