Why Compress Images?
Image compression reduces file size while preserving visual quality. Smaller images load faster, improve Core Web Vitals scores, and save bandwidth for your visitors. This is critical for SEO — Google uses page speed as a ranking factor.
Our compressor uses browser-native Canvas API to re-encode your images at the chosen quality level. WebP typically achieves 50–80% size reduction compared to uncompressed PNG, making it the best format for modern websites. JPEG works well for photographs, and PNG remains ideal when you need lossless transparency.
Unlike server-based compressors, ToolPix processes everything locally. Your images never leave your device, ensuring complete privacy. There are no daily limits, no watermarks, and no account required.

Frequently Asked Questions
What is the best format for image compression?
WebP offers the best compression ratio — typically 50-80% smaller than PNG with similar quality. Use JPEG for photographs and PNG only when you need transparency.
Does compression reduce image quality?
Lossy compression (JPEG, WebP) slightly reduces quality, but at 70-80% quality settings the difference is imperceptible to the human eye. PNG compression is lossless.
Is there a file size limit?
No. Since processing happens in your browser, the only limit is your device's available memory. Most devices handle images up to 50MB without issues.
Are my images uploaded to a server?
No. ToolPix compresses images entirely in your browser using the Canvas API. Your files never leave your device, ensuring 100% privacy.
Can I compress multiple images at once?
This tool processes one image at a time for maximum control. For batch processing, use our Bulk Image Resize tool which handles multiple files simultaneously.
