Compression Behavior & Transparency

Some pre-optimized images or complex PNGs with alpha transparency may not achieve significant reduction without format changes. Canvas re-compression preserves essential visual quality while discarding unneeded metadata.

Zero-Server Uploads

Your personal photos and sensitive images are compressed entirely inside your web browser using HTML5 Canvas APIs. Nothing is uploaded to our servers.

4 Frequently Asked Questions

Q. How does in-browser compression work without uploading files?

Your device browser reads the photo directly into memory using FileReader and redraws it onto an off-screen HTML5 Canvas. The canvas re-encodes the image at your selected quality level entirely on your device CPU/GPU.

Q. Why do some PNG images compress less than JPEGs?

PNG is a lossless format designed for crisp illustrations and transparency. If a PNG contains photographic colors, re-encoding without format conversion yields modest savings compared to JPEG or WebP.

Q. Will compressing my photo alter its width and height in pixels?

No. Compression optimizes encoding tables and removes excess metadata while keeping the original pixel dimensions completely unchanged.

Q. What is the recommended quality setting for blogs and websites?

A quality slider setting between 70% and 80% delivers the sweet spot between crisp image fidelity and lightweight file size for rapid page load times.
