How to compress a JPEG online
JPEG is the go-to format for photographs, but camera and export defaults leave a lot of wasted bytes on the table. OctoSqueeze re-encodes each JPG with a tested quality setting for the mode you choose and strips the metadata — the saving depends on the photo, and every result shows it.
Why smaller JPEGs matter
Lighter images load faster, improve your Core Web Vitals, and save bandwidth for you and your visitors. On mobile especially, a 2 MB hero image can be the difference between a bounce and a conversion.
Lossy vs. lossless
For JPEG we use lossy compression at a fixed quality per mode: size goes smallest, quality keeps the most detail. Need pixel-perfect output for graphics and screenshots? Switch to PNG compression instead.
Do it at scale
Compressing one image is easy. Compressing thousands is what our REST API is for — one call returns a download link for each optimized file, in any format you need.
Frequently asked questions
Everything you need to know about compressing JPEG images.
Contact supportJPEG compression reduces file size by removing image data that's less visible to the human eye. OctoSqueeze re-encodes each JPG with a tested quality setting for the mode you choose (size, balanced or quality) and strips metadata. How much smaller the file gets depends on the photo, and every result shows the exact saving.
With our balanced mode, the quality difference is imperceptible to most viewers. Our algorithm is optimized to preserve important details while removing only the data that won't be noticed. For critical images, use Quality mode for minimal compression.
