About Image Compressor

Free online image compressor that reduces the file size of your PNG, JPEG, and WebP images without significant loss in quality. Upload any image and use the quality slider to control the compression level. Choose your output format - convert to JPEG for smaller photos, WebP for modern web performance, or PNG for lossless transparency. See a real-time comparison of original vs compressed file size with percentage reduction. The tool uses your browser's Canvas API for fast, private compression - your images are never uploaded to any server. Perfect for optimizing images for websites, emails, social media, and reducing storage usage.

Frequently Asked Questions

How does image compression work?

Image compression reduces file size by removing redundant data. Lossy compression (JPEG, WebP) discards some visual information based on the quality setting - lower quality means smaller files but more artifacts. Lossless compression (PNG) reduces file size without any quality loss by optimizing how pixel data is stored.

Are my images uploaded to a server?

No. All compression happens locally in your browser using the Canvas API. Your images never leave your device, making this tool completely private and secure.

What is the best format for web images?

WebP offers the best balance of quality and file size for web use - typically 25-35% smaller than JPEG at equivalent quality. Use JPEG for photographs where WebP isn't supported, and PNG when you need transparency or lossless quality.

How much can I reduce my image file size?

Compression results depend on the image content and format. JPEG photos can often be reduced by 60-80% with minimal visible quality loss at 70-80% quality setting. PNG files with many colors can be converted to WebP for 30-50% savings. The tool shows the exact before and after file sizes so you can find the best quality-size balance.

Is this image compressor free?

Yes, completely free with no signup, no watermarks, and no file limits. Compress as many images as you need. All processing happens in your browser using the Canvas API - your images are never uploaded to any server.
