Up to 200 images at once

Skips files that are already small
Tiny or already-compressed images get copied as-is, so you do not waste time.
Common formats, simple output
JPG, PNG, WebP, and HEIC on Mac. Images come out as JPG so they are easy to share.

Your files never leave your computer
Everything runs on your Mac or PC. No website upload.
No upload needed
Online tools make you upload every file, then download every result. With a big batch, that can take hours, and it fails if your connection drops.
No daily limits
Free web tools often cap how many images you can do per day. Compresso runs on your machine. Pro is a one-time purchase, not a monthly fee for more minutes.
Private by default
Client photos, family albums, and work files stay on your computer. Nothing is sent to Compresso for compression.
