Web forms cap uploads, emails bounce heavy attachments, and pages load slower with every megabyte. This tool re-encodes your image with mozjpeg (or optimized PNG palette compression), shows you exactly how many kilobytes you saved, and never returns a file bigger than the original.

Frequently asked questions

How much smaller will my image get?

Photos typically shrink 40–80% at quality 75. PNGs with few colors compress dramatically via palette optimization; already-optimized files may shrink little β€” and if no gain is possible you get the original back.

Will I see the quality loss?

At 75+ most photos are visually indistinguishable at normal sizes. Below 50, compression artifacts become visible in gradients and fine detail.

Is EXIF data kept?

Orientation is applied and then metadata is dropped during re-encoding, which itself saves space and removes location data β€” a privacy bonus.

Does it work on screenshots?

Yes β€” PNG screenshots with flat colors and text compress especially well with palette optimization.

Your files stay private

Images are re-encoded in memory and discarded immediately after download. EXIF metadata (including GPS location) is stripped as a side effect of re-encoding, not collected.
