About this Tool
Make your website faster with smaller images. Our Image Compressor intelligently reduces the file size of your images while maintaining the best possible quality. It's the perfect tool for optimizing images for the web, email, or storage. The entire process is fast, free, and done securely in your browser.
This tool uses the HTML5 Canvas to re-process your image. By adjusting the quality settings of the encoder (for JPEG and WebP) and optionally resizing the image, it can create a new image with a significantly smaller file size.
- Upload your image.
- Choose your desired output format (JPEG, PNG, or WebP).
- Adjust the quality slider to find the perfect balance between size and quality.
- You can also resize the image at the same time.
- See the compression results in real-time and download your optimized image.
- Compressing photos before uploading them to your blog or website.
- Reducing the file size of an image to send it in an email.
- Optimizing images for a faster mobile experience.
- Intelligent Compression: Smart algorithms to reduce file size with minimal quality loss.
- Adjustable Quality: You have full control over the compression level.
- Resize & Compress: Change the dimensions of your image while compressing it.
- Multiple Formats: Works with JPEG, PNG, and WebP.
- Live Preview: See the 'before' and 'after' file sizes instantly.
- Private & Secure: Works entirely in your browser. Your images are never uploaded.
Image compression works by removing redundant or less noticeable data from an image file. 'Lossy' compression (like JPEG and WebP) can achieve very high compression ratios by discarding some data, while 'lossless' compression (like PNG) only removes redundant data.
How much can I compress my image?
It depends on the image, but it's common to see file size reductions of 50-80% with very little noticeable difference in quality.
Which format gives the best compression?
WebP is a modern format that generally provides the best compression. For photos, JPEG is also excellent. PNG is 'lossless', so it doesn't compress as well but perfectly preserves quality.
What's the maximum file size?
For best performance, it's recommended to use images under 50MB.
All image processing happens locally in your browser. No files are uploaded to our servers.
