About this tool

This image converter switches a photo between WebP, JPG, and PNG, and can shrink its width at the same time. Everything happens in your browser the moment you pick a file โ€” there is no upload step, so your image never reaches a server.

How to use

  1. Drag in or select the image you want to convert.
  2. Choose the target format: WebP, JPG, or PNG.
  3. Optionally pick a smaller width than the original (1920, 1280, 800, or 400px).
  4. For WebP or JPG, adjust the quality slider, then click convert and save.

Frequently asked questions

Which formats are supported?
WebP, JPG, and PNG. WebP usually gives the smallest file at the same visual quality, and PNG is lossless so it has no quality slider.
What happens to transparency when I convert PNG to JPG?
JPG has no transparency support, so any transparent area is filled with white. Keep WebP or PNG if you need to preserve a transparent background.
Can I also resize the image?
Yes. You can pick a width smaller than the original โ€” 1920, 1280, 800, or 400px โ€” and the height scales automatically to keep the aspect ratio.
Is my photo uploaded to a server?
No. From the moment you select a file to the final download, everything runs in your browser and the image data never leaves the page.
