Compressed Images
100% Private
All compression happens in your browser using the Canvas API. Your images are never uploaded to any server.
Up to 90% Smaller
Convert PNG to WebP for dramatic file size reductions. WebP is ~30% smaller than JPEG at the same quality.
Batch Processing
Upload and compress multiple images at once. Download individually or all at once in one click.
Image Compression FAQs
Common questions about image compression and WebP format.
WebP is a modern image format developed by Google that provides superior compression for images on the web. WebP lossy images are about 25–34% smaller than comparable JPEG images at the same quality. WebP lossless images are about 26% smaller than PNGs. WebP also supports transparency (like PNG) and animation (like GIF). All major browsers support WebP. Using WebP for your website images significantly improves page load speed and Core Web Vitals scores.
For most web images, 70–85% quality provides an excellent balance between file size and visual quality — most people can't tell the difference from 100% at these settings. For product photography or images where fine detail matters, use 85–90%. For background images or decorative graphics, 60–70% is fine. For thumbnail previews, 50–65% saves significant bandwidth. Below 50%, compression artifacts become visible in photos.
By default, this tool only reduces quality (lossy compression) without changing dimensions. You can optionally set a Max Width to also resize images — useful for when you upload high-resolution photos (e.g., 4000px wide) that only need to display at 1200px. Resizing combined with quality reduction gives the greatest file size savings. The aspect ratio is always preserved — height adjusts proportionally to the new width.
Lossless compression preserves every pixel exactly — the decompressed image is identical to the original. Set quality to 100% in this tool for near-lossless compression (some reprocessing overhead still applies). For true lossless PNG compression, tools like PNGCrush or ImageOptim work by removing metadata and optimizing the PNG filter without touching pixel data. Lossless compression typically reduces file size by 10–30%, while lossy compression can reduce by 60–90%.
