Why WebP & AVIF are Recommended
WebP and AVIF provide superior lossless and lossy compression. WebP images are typically **26% smaller** in size compared to PNGs and **25-34% smaller** compared to JPEGs, while maintaining rich transparency support and reducing page load times.
Target Size Compression
Visa applications, job portals, and official submission forms often enforce strict limits (e.g. \"Max 200 KB\"). Instead of manual trial-and-error resizing, our smart bisection compression automatically adjusts quality variables iteratively to fit exactly.
100% Client-Side Privacy
Most popular online compressors require you to upload files to their servers. We process pixels **directly in your browser** using HTML5 Canvas. Your sensitive document photos, confidential screenshots, or private images **never** leave your local computer.
Overview & Capabilities

Frequently Asked Questions
Q How does lossy vs lossless image compression work?
Lossless compression reduces file size by eliminating redundant metadata without changing pixel data. Lossy compression subtly simplifies imperceptible color gradients to achieve 70–90% smaller file sizes with near-identical visual fidelity.
Q Are my confidential photos uploaded to your servers during compression?
No. All compression algorithms execute locally within your browser's HTML5 Canvas context. Your photos never leave your device.
Q What is the recommended compression quality for website images?
A quality setting between 75% and 85% provides the ideal sweet spot—slashing file size by 60–80% while remaining visually indistinguishable from the original uncompressed image.
