How do I change an image from one format to another, like PNG to JPG or WebP?

Short answer

Use a browser-based image format converter that re-encodes the picture between PNG, JPG and WebP on your own device. It is free with no sign-up, and because the conversion runs locally the image is never uploaded to a server.

Pick the format for the job

PNG is lossless and keeps transparency, which suits logos, icons and screenshots with sharp text. JPG discards a little detail for a much smaller file and is right for photographs. WebP usually beats both on size for the web while still supporting transparency. Converting between them is simply a matter of decoding the picture and re-saving it in the target encoding.

Why local conversion matters

A format converter that runs in your browser opens the file, decodes it and writes out the new format all on your device, so an unpublished product shot or a screenshot with private information never travels to anyone else. There is no queue, no account and no per-file cap; a companion converter handles the specific WebP round trips when a site or app refuses to take one format.

Step by step

  1. Add your image. Open the format converter and select the picture you want to change.
  2. Choose the output format. Pick PNG, JPG or WebP depending on where the image needs to go.
  3. Download the result. Save the converted image straight from your browser.

Frequently asked questions

Is my image uploaded to convert it?

No. The conversion runs entirely in your browser, so the file never leaves your device.

Which formats are supported?

Common web image formats: PNG, JPG and WebP, converted in any direction.

Will converting lose quality?

Converting to PNG is lossless. Converting to JPG or WebP re-encodes with a quality setting, so pick a level that keeps the picture looking right.
