Compress images to a target size

Reduce photos to a specified size, such as 100KB, 200KB, or 500KB, and save multiple images as ZIP.

Reduce image size, use it like this

Select up to 20 PNG, JPEG, or WebP, then specify target KB per file and output format. Check the Start Quality, Minimum Quality, and Maximum Long Side and press Reduce Size. Check the resulting volume and pixel dimensions, then download individual files or a ZIP of the files that meet your goal.

Example usage

If you input 200 KB, aim for no more than 200,000 bytes per file. Even if you apply the same settings, the resulting quality and size will vary depending on the image content. Results exceeding targets are displayed separately and excluded from the ZIP.

Please note

Process up to 20 files, with a 20MiB limit per file and 100MiB total. Each image must be at most 16 million pixels AND 8192px on each side. JPEG fills transparency with white. Output is a still image; EXIF metadata and animation are not preserved. Your quality and dimension limits may prevent the target size from being reached.
