How to reduce image size

  1. Choose one or more JPG, PNG or WebP images.
  2. Set the quality and output format.
  3. Compress and download each result.

What quality should I use?

For typical web photos, 75–85% is often a useful balance. Compare PNG and WebP for graphics with text or transparency.

Will image quality change?

Lossy JPG and WebP encoding can remove subtle detail. FileNexa shows both file sizes so you can judge the tradeoff.

Image compression FAQ

Is my image uploaded?

No. Compression happens locally in your browser and the image never reaches our server.

Why might a PNG not get smaller?

Browser canvas exports PNG losslessly and may not reduce its size. Try WebP when a smaller file matters.
