How browser-based image compression works
Lossy vs lossless compression
JPG and WebP use lossy compression — reducing quality slightly can cut file size by 60-80%. PNG uses lossless compression, so quality is preserved but file-size savings come from optimising the encoding. This tool lets you adjust the quality slider to find the right balance.
Why compress images?
Smaller images load faster, improve Core Web Vitals scores, reduce bandwidth costs, and make your site feel snappier on mobile. Google uses page speed as a ranking signal, so optimised images directly help SEO.
No file-size limits
Server-based compressors often cap uploads at 5-10 MB. Because this tool runs locally, the only limit is your browser's available memory — you can compress large DSLR photos or batch-process dozens of files without hitting a wall.
Privacy-safe compression
Compressing images on a remote server means your full-resolution originals are transmitted over the internet and stored (at least temporarily) on someone else's infrastructure. Client-side compression avoids this entirely.
