How Convert Image Formats Works: Keep Your Files Safe & Private
See step-by-step how your files are processed. Everything happens right inside your browser — your files are never uploaded to the internet or shared with anyone.
1. Open on Your Device
When you pick a file, your browser opens it directly on your computer or phone. Your document stays on your device and is never uploaded anywhere.
2. Process in Your Browser
Your device does all the work right inside your browser. Because there are no server queues or waiting lines, your files are processed instantly.
3. Save in Private Vault
When you save your work, your file is stored securely inside your browser's private vault on your device. You can view or reopen it anytime, even without internet.
4. Download, Reuse, or Delete
Download your finished file, send it directly to another tool without re-uploading, or click 'Clear Vault' to permanently erase your files anytime with one click.
How You Can Prove Your Files Never Leave Your Device
Open this tool, turn off your Wi-Fi or turn on Airplane Mode, and drop your file. It will still edit, convert, or compress and let you download the result! This proves the tool works completely offline without sending anything to any server.
Press F12 on your keyboard (or right-click anywhere and choose "Inspect"), click on the Network tab, and process your file. You will see 0 bytes of your file sent over the web — absolute proof of 100% privacy.
