  2. Choose a quality level with the slider.
  3. Compare the original and compressed file size.

Supported formats & limitations

  • JPG / JPEG
    Best for photographs, adjustable lossy quality.
  • PNG
    Lossless; compression gains depend on image content.
  • WebP
    Modern format with strong compression at similar quality.
  • Very large images may take longer to process on lower-powered devices.
  • PNG compression results vary more than JPEG or WebP.

Frequently asked questions

Does compressing change the image quality?

Lower quality settings reduce file size but can introduce visible compression artifacts, especially on JPEG and WebP. Compare the preview before downloading.

Is there a file size limit?

The tool works best under 50 MB; very large files depend on your device’s available memory.

Is my image uploaded anywhere?

No. The image is decoded and re-encoded entirely in your browser using the Canvas API.

Troubleshooting

Why is the compressed file barely smaller than the original?

Some images (especially ones already compressed by a phone camera or another tool) have little redundant data left to remove. Try a lower quality setting or a different output format.

Why does my image look blurry or blocky after compressing?

Very low quality settings trade sharpness for a smaller file. Move the quality slider higher and compare the preview before downloading.
