loot.toolsCompress JPEG, PNG, or WebP images right in your browser. Nothing is uploaded to a server.
Upload an image and drag the quality slider to trade a little visual detail for a much smaller file. You see the original and compressed versions next to each other along with both file sizes and how much you saved. You can also convert to WebP, which usually compresses better than JPEG at the same quality.
Large images are the main reason web pages load slowly. A single uncompressed photo can be several megabytes, while a compressed version often looks identical at a tenth of the size. Smaller images mean faster page loads, lower bandwidth bills, and better Core Web Vitals scores, which Google uses for ranking.
The image is decoded and re-encoded by your browser's canvas engine at the quality you pick. JPEG and WebP are lossy, so lower quality means smaller files. PNG is lossless, so the quality slider doesn't apply there. Your image never leaves your device, which makes this safe for screenshots, private photos, and work files.
