Image Compressor

Compress JPEG, PNG and WebP images in bulk — right in your browser, with no uploads.

Images are never uploaded. Everything is processed in your browser.

What is this tool?

A free image compressor for batches of up to 20 images. Choose an output format, quality and optional resize preset, then download files individually or as a single ZIP.

How to use

  1. Drop images or choose them from your device.
  2. Adjust output format, quality and size.
  3. Download each result, or everything as a ZIP.

Use cases

  • Shrinking photos before sending them by email or chat.
  • Reducing image weight for faster websites.
  • Converting photos to WebP while compressing them.

Notes

  • PNG output is lossless, so the quality slider has no effect there.
  • All processing happens locally in your browser.

FAQ

Are my photos uploaded?

No. Compression runs entirely in your browser, and images are never sent to a server — safe for private photos.

Why did a file download at its original size?

If compression would make the file larger (already well-optimized images), the original file is kept instead of making it worse.

Which formats are supported?

JPEG, PNG and WebP input. Output can stay in the original format or convert to JPEG, WebP or PNG, with optional resizing by the long edge.
