Choose file

A page loads only as fast as its heaviest image, which is usually the first place worth checking before optimizing anything else. Add a JPG, PNG, or WebP file, move the quality slider, and see the original size next to the new one before deciding whether to download.

What this tool does

The image is re-encoded at the quality setting you pick, and the tool reports exactly how many bytes were saved — or warns you if the new file actually turned out larger than the original.

How to use it

  1. Add an image in JPG, PNG, or WebP.
  2. Adjust the quality slider.
  3. Process the file, review the savings, then download.

What you get

  • A before-and-after size comparison shows the real result.
  • A percent-saved indicator makes the trade-off easy to judge.
  • Works across JPG, PNG, and WebP without switching tools.

Typical uses

  • Shrinking a hero image before it slows down a landing page.
  • Getting a photo to a size that's easy to email.
  • Compressing a batch of images one at a time during a redesign.

Examples

  • A 2 MB JPG at 70% quality often shows a noticeable size reduction.
  • A PNG with mostly flat colors may barely shrink, since it's already efficient for that kind of image.

Worth knowing

  • Re-encoding a PNG rarely helps much, since PNG compression already handles flat-color images well.
  • Setting quality too low can blur small text, which matters most in screenshots.

Frequently asked

Will compression always help?

Not always. A JPG that's already well optimized can even grow slightly if the quality setting is too high for its content.

Is metadata kept?

Exporting through canvas typically strips EXIF metadata, so location and camera details won't carry over to the new file.
