How it works

Choose photos, adjust your settings, compare, and save.

1. Choose photos

Choose up to 20 JPG, PNG or WebP files. Limits are 20MB per file, 100MB total, 8192px per side and 25 megapixels. Animated or damaged images are not supported.

2. Set the output

Quality affects lossy JPG and WebP encoding. PNG is lossless and can grow. Turn on a target size for a byte limit. 1KB means 1000 bytes.

3. Adjust dimensions

Longest edge never enlarges smaller images. Exact dimensions can fit the whole image with padding or crop the center. Check the background when saving transparent images as JPG.

4. Compare and save

Move the comparison slider to inspect details. Larger files and missed size targets are flagged. Files that miss the target are excluded from the ZIP. Total output is capped at 60MB. Changing settings clears old results and requires processing again.
