How to use the image compressor
- Choose or drop one or more images.
- Adjust the quality and, if you like, a maximum size.
- Download each file, or all of them as a ZIP.
Which settings to use
For photos, a quality of 70–80% is usually impossible to tell apart from the original and often 60–90% smaller. Screenshots and graphics with flat colours compress best as PNG or WebP. Making a 4000-pixel photo 1920 pixels wide shrinks it more than any quality setting.
Why a file sometimes doesn’t shrink
If an image is already well compressed, saving it again can make it bigger. In that case the tool keeps your original file and tells you.
