How to compress an image to a file-size limit

  1. 01

    Choose an image

    One PNG, JPEG, or WebP; up to 12 MiB, 8,192 pixels per side and 24 million pixels.

  2. 02

    Set the byte limit and output format

    The target is an upper byte limit, not an exact size or visual-quality guarantee. JPEG and WebP search between 50% and 95% encoder quality. Dimensions stay unchanged. A closest result still exceeds the limit; inspect the image before using it.

  3. 03

    Check the result and download

    PNG is re-encoded without a quality search and may not get smaller. Choose JPEG or WebP explicitly for lossy compression. JPEG replaces transparency with the selected background color.

Common questions

Which formats are supported?
One PNG, JPEG, or WebP; up to 12 MiB, 8,192 pixels per side and 24 million pixels. PNG is re-encoded without a quality search and may not get smaller. Choose JPEG or WebP explicitly for lossy compression.
Does the target guarantee an exact size?
The target is an upper byte limit, not an exact size or visual-quality guarantee. JPEG and WebP search between 50% and 95% encoder quality. Dimensions stay unchanged. A closest result still exceeds the limit; inspect the image before using it.
Does my image leave this device?
Processing stays in this browser. The original is unchanged; the new file is re-encoded and checked for metadata removal. Closing or resetting the workspace discards its in-memory files.
