Free Online Image Compress Tool

Free online Image Compress: JPG/PNG/WebP compression. No software installation, works right in your browser, completely free.

How Image Compress Works

Image Compress shrinks JPG, PNG and WebP files with live size estimates before you commit. Pick a compression level, watch the projected saving for every file, and download results individually or as a ZIP — all processed locally, so photos never leave your device.

  3. Preview the projected size for each file before compressing.
  4. Click “Compress All” and download files individually or as a ZIP.

Typical Use Cases

Speed up your website

Compress product and blog images so pages load faster and consume less CDN bandwidth.

Meet upload size limits

Shrink photos to fit forms, marketplaces and apps that cap file size at 5MB or 10MB.

Free up phone storage

Batch-compress a camera roll before backing it up or sharing it in chat groups.

Normal is the everyday sweet spot for website images and chat sharing. Use Light for photos you will print, and Strong/Extreme for attachments or upload forms with tight limits. Since compression runs locally, batch compressing a folder of personal photos stays completely private.

FAQ

Which format saves the most?

Photographs compress best as JPEG; screenshots and graphics with flat colors often shrink dramatically as WebP. The live estimate shows you the saving per file before you start.

Will compressed images lose visible quality?

At Light and Normal levels the difference is nearly invisible. Strong and Extreme trade some detail for size — preview the estimate and choose the level that fits your use case.
