Image Compressor

Design & Media

Compress and resize images

The Image Compressor reduces the file size of your images while maintaining visual quality. Upload a JPEG, PNG, or WebP image, adjust the compression quality, and download the optimized version. The tool shows you the original and compressed file sizes so you can see exactly how much space you saved.

Large images are one of the biggest contributors to slow website load times. Compressing images before uploading them to a website, blog, email, or social media platform improves performance, reduces bandwidth usage, and provides a better experience for visitors.

All compression happens locally in your browser using the HTML5 Canvas API. Your images are never uploaded to any server, making this tool completely private. Process sensitive images with confidence knowing they stay on your device.

How to Use

  1. Click the upload area or drag and drop an image file (JPEG, PNG, or WebP).
  2. Adjust the compression quality slider. Lower values produce smaller files with more compression.
  3. Preview the compressed result to check for acceptable quality.
  4. Compare the original and compressed file sizes displayed below the preview.
  5. Click Download to save the compressed image to your device.

Frequently Asked Questions

How much can I reduce the file size?

Typical compression ratios range from 50% to 90% size reduction depending on the image content and quality setting. Photographs compress more efficiently than graphics with sharp edges and text.

Will compression make my image look bad?

At moderate quality settings (60-80%), the difference is usually invisible to the human eye. Very low quality settings (below 30%) will show visible artifacts, especially on photographs.

Is there a file size or resolution limit?

Since processing happens in your browser, very large images (over 20 megapixels) may be slow to process. There is no strict file size limit, but browser memory constraints apply.

Are my images uploaded to a server?

No. All compression is done locally in your browser using the Canvas API. Your images never leave your device.
