Compress an image online
Shrink file size with a quality slider — upload faster, fit platform limits.
Large photos slow down page loads, blow past email attachment limits, and eat into upload quotas. Compress reduces file size using an adjustable quality slider, so you can trade a little visual quality for a much smaller file when it matters.
How to compress image
- Drop a JPG, PNG, WebP or HEIC image into the upload area — maximum 50 MB.
- Adjust the quality slider — lower quality means a smaller file.
- Click "Compress image" and download the result.
Common use cases
- Shrink a photo to fit an email attachment limit.
- Speed up a website by compressing its images.
- Fit an image under a platform’s upload size limit.

Frequently asked questions
What if my image is already well compressed?+
You’ll get an "Already optimized" message and the original file, instead of a misleadingly larger result.
Which formats compress best?+
JPG and WebP support real lossy compression; PNG compression is lossless, so gains are smaller depending on the source image.
