What is the Image Compressor?

The Image Compressor reduces an image’s file size by adjusting its quality level. JPEG and WebP are lossy formats, so even a small reduction in quality can meaningfully shrink the file size.

All processing happens entirely in your browser using the Canvas API — your image data is never sent to a server. If you need to significantly shrink a PNG, consider using the Image Converter to switch it to WebP or JPEG first.

Use Cases

  • Shrink images to improve a website's page load speed
  • Compress an image to fit within an email attachment or upload size limit
  • Reduce the size of a high-resolution phone photo before posting it to a blog

How to Use

  1. Select an image file, or drag and drop it into the drop zone.
  2. Choose an output format (JPEG, WebP, or PNG).
  3. Adjust the quality slider to control how much the image is compressed.
  4. Click "Compress" to see the before/after file size.
  5. Click "Download" to save the compressed image.

FAQ

Is this tool free?

Yes, it is completely free to use.

Is my image sent to a server?

No. All processing happens in your browser using the Canvas API. Images are never uploaded to a server.

How much can a PNG be compressed?

PNG is a lossless format, so re-encoding alone won't shrink it much. For a bigger reduction, we recommend converting to WebP or JPEG instead.

How low should I set the quality?

It depends on your use case, but for web display, 70-85% often keeps visual quality nearly intact while noticeably reducing file size.
