How to use Image Format Converter — step by step
- 1Open the tool you want. Done — this page is saved in your browser, so it opens with no connection.
- 2Turn on airplane mode (optional).Anyone can claim a tool is private. Airplane mode is what proves it — with the connection off, there's nowhere for your file to go. Skip it and everything still works, but you won't have the added privacy protection of a 100% internet disconnect.Press the airplane-mode button on your own phone, tablet or laptop.The switch is on your device, not on this page. On some laptops and phones the airplane button leaves Wi-Fi or Bluetooth running — if the instrument still shows a connection, turn those off yourself. It reads Offline the moment the connection is really gone.
- 3Add your image.
- 4Choose the format you need — PNG, JPG, or WebP.
- 5Tap convert.
- 6Download the converted image.
