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.
Your personal photos and sensitive images are compressed entirely inside your web browser using HTML5 Canvas APIs. Nothing is uploaded to our servers.
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.
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.
No. Compression optimizes encoding tables and removes excess metadata while keeping the original pixel dimensions completely unchanged.
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.
