Image Compressor

An image compressor shrinks file sizes by re-encoding images more efficiently — smarter quality settings, optimized encoding, metadata stripping — typically cutting 50–90% of the bytes while looking identical at normal viewing. A 4 MB photo becomes 400–800 KB nobody can tell apart.

The waste it removes is real: cameras and phones save at conservative quality settings and carry metadata payloads; design exports default to maximum quality. The gap between "as saved" and "as needed" is the compressor's harvest — and on the web, images are half of page weight, making this the highest-ROI speed tool that exists.

Upload the image, compress, download the smaller file — with the size saving shown.

Where the bytes matter: web pages (compressed images are the fastest Core Web Vitals win — LCP is usually an image, and 70% off the hero image is 70% off its load time), email and messaging (under attachment caps without visible loss), storage (a photo library recompressed reclaims real gigabytes), and upload forms with size ceilings.

How the savings happen per format: JPG — perceptual quality tuning (quality 80 looks like 95 at half the size) plus metadata stripping; PNG — palette optimization and better DEFLATE (lossless — identical pixels, smaller file); WebP — efficient re-encode. The craft is the quality floor: compress to just above where artifacts appear, which for photos is far lower than defaults. Compress once from originals — recompressing compressed JPGs compounds loss. Files are processed and returned, never stored.
