Your privacy is our mission. Most files are converted right in your browser and never leave your device. Only large files, or formats a browser cannot process, are sent to our server over an encrypted connection — they are never stored, never shared, and deleted as soon as your download is ready.
Is There Really No Limit?
There is no limit on the number of conversions per day, no account and no paid tier. The one limit is file size — 10 GB per file — which is the same for everyone. The service is paid for by the ads on the page.

Why It Can Be Free
Most conversions run in your own browser, on your own device, so they cost the service almost nothing. Only what a browser cannot do — document layout, some image and video formats, very large files — runs on the server. Ads on the page cover that.
Frequently Asked Questions
Do I have to sign up after a few conversions?
No. There is no account system at all.
Is anything added to my files?
No watermark, no logo, no extra page.
What is the catch?
There are ads on the page. Very fast repeated requests from one address are slowed down to protect the service — an ordinary batch is not affected.
