Compress image makes JPG, PNG and WebP photos smaller while keeping them sharp. It uses the same encoders the big image sites use (MozJPEG, OxiPNG and WebP), and it can also shrink a photo to an exact size in KB for upload forms.
When to use Compress image
- Make photos small enough to email or send on WhatsApp
- Bring a photo under the KB limit of a job or exam form
- Speed up a website by shrinking product photos and screenshots
How to use Compress image
- Add up to 30 images.
- Pick a level: Best quality, Recommended or Smallest, or choose "Target KB" and type the size you need.
- Click Compress. Each image shows its old and new size, and the files download as one ZIP when there are several.
Tips
- PNG screenshots and logos shrink the most with Recommended, which reduces colours without visible change.
- Choose "Save as WebP" for the smallest files if the place you upload to accepts WebP.
Questions about Compress image
Are my photos uploaded?
No. Images are compressed inside your browser and never leave your device.
How many images can I compress for free?
Up to 30 at a time, with no sign-up.
Will the photo look worse?
At Recommended most people cannot see a difference. Smallest trades a little detail for much smaller files.
Is it safe?
Yes. Compress image works inside your browser. Your files are not uploaded anywhere, so nobody else can see them, and there are no waiting queues.
