Compress and convert ​

The Compress tab makes an image smaller by saving it again at a lower quality. The Convert tab changes its format. Both work on the image selected in the popup.

Compress an image ​

  1. Import an image and open the Compress tab.

  2. Set Quality from 1 to 100. It starts at 80.

  3. Choose an Output format: JPG, WebP, PNG or AVIF.

  4. Check Output size and Saved, and look at the preview.

  5. Select Download.

The download is named after the original with -compressed added.

Which format to choose ​

  • JPG suits photos and works everywhere.
  • WebP is usually smaller than JPG at the same quality and keeps transparency. Most current browsers and apps open it.
  • AVIF is often smaller still, but some older apps cannot open it.
  • PNG is lossless and keeps transparency. The Quality slider has little effect on PNG, so a PNG photo rarely gets much smaller. Choose WebP or JPG to shrink one.

If your browser cannot create AVIF files, the option shows AVIF (not supported) and cannot be picked.

TIP

If Saved shows 0%, the image was already well compressed at that setting. Lower the quality, switch to WebP, or make the image smaller on the Resize tab.

Convert an image ​

  1. Import an image and open the Convert tab.

    Source format shows the image's current format.

  2. Under Convert to, select JPG, PNG, WebP or AVIF.

    The button for the image's current format is greyed out. The conversion starts as soon as you select a format, and Output format and Output size fill in.

  3. Select Download.

The download is named after the original with -converted added, for example logo-converted.png. Converting saves JPG, WebP and AVIF at a high quality (92), so the file may grow compared with a compressed original.

Saving a transparent image as JPG, here or on the Compress tab, fills the transparent areas with white, because JPG has no transparency.

Metadata is removed ​

Compressing or converting removes EXIF metadata, such as the camera model, date and GPS location. This is deliberate, so you do not share that data by accident. To see whether the original had EXIF data, use the Metadata tab before you process it.
