Why BrowserTools?
Your files stay yours
Other converters upload your photos and documents to servers you can't see. Here, conversion, compression and background removal all happen on your own device — private by architecture, not by promise.
No paywalls, no accounts
Every one of the tools is free with no signup, no email, no watermark and no daily limit. Bookmark the ones you love and use them forever.
Fast on any connection
Pages are static and lightweight, tools load on demand, and most of them keep working even if your connection drops mid-task.
