Quick answer

To compress an image without obvious quality loss, resize oversized photos first, choose JPG or WebP for photos, and use the highest quality setting that still meets your file-size limit.

Quick steps

  1. 01.Upload your image.
  2. 02.Choose a format and quality level.
  3. 03.Compare before and after size before downloading.

Use the right format

JPG is usually best for photos, PNG is useful for transparency, and WebP is strong for modern websites.

Resize before heavy compression

A huge image can stay too large even at low quality. Reducing dimensions first often creates a better-looking result.

Common mistakes to avoid

  • Trying to force a very large camera photo into a tiny file size without resizing.
  • Using PNG for photos when JPG or WebP would usually be smaller.
  • Choosing the lowest quality setting before checking a balanced setting first.

Guide FAQs

Can compression be completely lossless?

PNG can be lossless, but photos usually need JPG or WebP compression to become much smaller. That can reduce detail if pushed too far.

Should I resize before compressing?

Yes, if the original image is very large. Smaller dimensions usually make strict file-size targets easier to reach.
