Image Compressor (Compress Images)

Compress JPG, PNG and WebP images — one or many at once. Reduce file size with a quality slider while keeping the format, see the savings, and download all as a ZIP. Private, no uploads.

Quality 75%

JPG · PNG · WebP — compressed in your browser, format kept, nothing uploaded
Lower quality = smaller files. PNGs are re-encoded (for big savings, try converting PNG photos to WebP). 100% private — nothing is uploaded.

What is Image Compressor?

Image Compressor shrinks image file sizes by re-encoding them at a quality level you choose, keeping the original format. Add one image or a whole batch, set the quality, and see the exact size saved on each. It runs in your browser, so nothing is uploaded.

How Image Compressor works

How to compress images

  1. Add your JPG, PNG or WebP images (single or bulk).
  2. Move the quality slider — lower means smaller files.
  3. Download each compressed image, or all of them as a ZIP.

Photos compress best as JPG/WebP. PNG is lossless, so for big savings on photo-like PNGs, convert them to WebP.
