Free online image converter

Convert images to modern, web-friendly formats without uploading them to a server. WebP is selected by default because it offers an excellent balance between quality and file size for websites.

How to convert an image

  1. Drop one or more images into the converter or choose files from your device.
  2. Select WebP, JPG, or PNG as the output format.
  3. Adjust quality, and set a custom width or height if you need one.
  4. Click Convert images and download the optimized files — or download them all at once as a ZIP.

Which image format should I use?

WebP is a strong default for websites. JPG is ideal for photographs and broad compatibility. PNG is useful when transparency or lossless output is important.

Is this image converter private?

Yes. Conversion happens locally in your browser. Your original images are not uploaded to SimpleTools or sent to a remote server. Metadata is not preserved when an image is re-encoded through the browser canvas.
