How it works

Image Compressor in 4 steps

  1. Drop an image onto the tool or click Choose File.

  2. Drag the quality slider and watch the output size update.

  3. Compare the compressed preview against the original for artifacts.

  4. Download when the size and quality balance is right.

When to use it

Shrink image file sizes with full control: drag the quality slider, see the exact output size instantly, and download when it's small enough. Compression runs on your device - the image never leaves your browser.

  • Get email attachments under a 10MB or 25MB limit.
  • Compress hero images so your site's Largest Contentful Paint improves.
  • Shrink a whole shoot before archiving with Pro batch.

Format & quality notes

  • JPG and WebP inputs are recompressed in their own format. PNG inputs are converted to WebP for compression - that's what makes PNGs dramatically smaller.
  • Quality 0.7-0.8 is the sweet spot for photos; text and UI screenshots need 0.85+.
  • Compression also strips EXIF metadata from the output.
FAQ

Questions about the Image Compressor.

How small can my image get?

Photos typically compress 60-90% smaller depending on the source and quality setting. The live readout shows the exact output size before you download.

Why does my PNG come out as WebP?

PNG is lossless, so recompressing it as PNG barely helps. Converting to WebP is how you get real savings while keeping transparency. If you need PNG output, use the resizer or converter instead.

Is there a quality level I shouldn't go below?

Below 0.5, most photos show visible blockiness. Use the side-by-side preview - your eyes are the best judge.

Is my photo uploaded to compress it?

No. The compressor runs in your browser. Nothing is transmitted or stored.
