🗜️ Image Compressor

Make image files smaller for email and websites. Nothing is uploaded.

Your image stays on your device. Transparent areas become white in JPEG.

How to use the Image Compressor

  1. Choose an image.
  2. Set the quality and output format.
  3. Select Compress image, check the saving and download.

Examples

  • Results vary by image. Lowering quality to 75% often reduces photos noticeably.

Formula and method

The image is redrawn on a canvas at its original dimensions and exported as JPEG or WebP at the chosen quality. If the result is not smaller, try lower quality or WebP.

Frequently asked questions

Why can the result be bigger?

Already-optimized images may not shrink further.

Does it change dimensions?

No. Use the Image Resizer for that.
