How to compress an image

  1. Upload your image (JPG, PNG, WebP, or HEIC).
  2. Choose Compress and set the quality: lower means a smaller file.
  3. Download the result and compare it with your original before sharing.

A practical starting point

Lower quality gradually on a copy. Compare facial detail, small text and sharp edges at 100% zoom rather than in a thumbnail.

Frequently asked questions

What are the limits of Compress Image?

Already compressed images may shrink little. Repeated lossy saves accumulate artifacts. Transparency and metadata behavior depend on format and processing path.

How should I check the Compress Image result?

Compare downloaded bytes with the original. Resize unnecessarily large dimensions instead of repeatedly compressing. Keep a lossless original for future edits.
