Compress Image

Shrink a JPG or WebP with an adjustable quality slider. Processed on your device — nothing uploaded. (PNGs are re-encoded as JPEG for compression, since PNG doesn't support a quality setting; use Convert Image first if you need to keep transparency.) Subscribers can compress multiple images at once and download them as a ZIP.

How to use this tool

Compress Image shrinks a JPG, PNG, or WebP file's size with an adjustable quality slider, re-encoded locally on your device.

Select an image (subscribers can select several at once).
Move the quality slider to balance file size against sharpness.
Download the compressed image, or the ZIP if you compressed a batch.

Compressing a PNG converts it to JPEG, which drops transparency — use Convert Image first if you need to keep it.
