JPG, PNG, WebP, GIF, BMP — multiple files supported

Higher strength = smaller file, lower visual quality. PNG output is lossless, so strength only affects downscaling for PNG — pick JPEG or WebP for the biggest size reduction.

Images are processed locally using the browser's Canvas API. They are never sent to a server.

How to compress an image online for free

  1. Click the box above and choose one or more images (JPG, PNG, WebP, GIF), or drag them in.
  2. Pick an output format and quality/size settings.
  3. Let it re-encode each image locally in your browser.
  4. Download the compressed images — nothing is uploaded anywhere.

Why compress an image?

Uncompressed photos and screenshots can be several megabytes each, which slows down websites, blows past email attachment limits, and wastes storage. Re-encoding images at a sensible quality level can cut file size by 50–90% with little visible difference.

Frequently asked questions

Which image formats are supported?

JPG, PNG, WebP, GIF, and most other common formats your browser can decode.

Are my images uploaded anywhere?

No. Everything is processed locally using the browser's Canvas API — images never leave your device.

Can I compress multiple images at once?

Yes, you can select or drag in multiple files and compress them in a single batch.

Will I lose image quality?

Compression is lossy at higher settings, so there's a size/quality tradeoff. Lower compression keeps more detail; higher compression produces smaller files.

Is this tool free and unlimited?

Yes — no sign-up, no watermark, and no artificial limit on the number of images.
