Image Compressor is a browser-based optimization tool designed to reduce the storage size of digital images (JPEG, PNG, WebP) by utilizing lossy canvas encoding and resolution adjustments.

2. Adjust the Quality slider to balance file size and visual clarity.

3. Optionally adjust the Scale slider or enter custom Width/Height to resize the resolution.

4. Slide the side-by-side divider to compare the original vs. compressed image.

5. Click "Download Compressed Image" to save the optimized file.

Pro tips

  • For the best balance of file size and visual quality, convert PNG screenshots to WebP with 80% quality. This often reduces file size by over 80%.
  • Use the side-by-side comparison slider to zoom in or slide back and forth to inspect fine text and details for compression artifacts.

Frequently asked questions

Is my image uploaded to any server for compression?

No. The compression is performed entirely client-side inside your browser using HTML5 Canvas. Your images never leave your computer, ensuring 100% privacy.

Which formats are supported for compression?

This tool supports PNG, JPEG, and WebP formats. You can also convert between these formats during the compression process.

How does the quality slider affect my image?

For lossy formats like JPEG and WebP, the quality slider controls the compression level (from 10% to 100%). Lower values yield smaller file sizes but may introduce compression artifacts. A value of 80% is usually the sweet spot for web use.

Can I resize the dimensions of the image?

Yes. You can scale down the image by a percentage (e.g., 50%) or enter custom width and height dimensions. By default, the aspect ratio is maintained to avoid stretching.
