How can I check that nothing is uploaded?
Your files are processed in this browser tab. This page has no function that sends files to a server, and its security rules (Content Security Policy) forbid connections to other servers.
Check it yourself: load this page, then switch on flight mode or disconnect Wi-Fi and run the tool. It still works – because everything happens on your device.
Good to know
How it works – step by step
Paste the texts
Paste the old version on the left and the new one on the right – from emails, contracts or websites.
Choose how
Compare by words, characters or lines. Case and spacing can be ignored.
See the differences
Deleted text is struck through, new text underlined – inline or side by side, with counts.
Why FaLe?
No upload
Both texts stay on your device – important for contracts, applications and internal documents.
Words, characters or lines
By words for prose, by characters for typos, by lines for lists and code.
PDFs too
For two PDF versions there is “Compare PDF” with a page view.
