How to compress a JPEG image

Choose a JPEG photo in the compressor above and adjust any available quality or size controls. Download the result and compare its file size with the original. Check the image at normal viewing size to make sure faces, text and important details remain clear.

Understand JPEG compression

JPEG uses lossy compression to reduce the amount of data needed to store a picture. More aggressive settings can introduce blocky artifacts, blurred edges and color banding. Reducing overly large pixel dimensions can also lower file size, but the best settings depend on whether the image is for a website, messaging app or official upload.

Avoid unnecessary quality loss

Keep the original image and create new compressed versions from it rather than repeatedly saving an already compressed file. Inspect areas with fine details and strong contrast. For documents or ID photos, follow the receiving organization’s requirements for image dimensions, background, format and file size.

Frequently asked questions

Will JPEG compression always reduce file size? Results vary with source content and settings. Can it restore a blurry image? No; compression cannot recreate lost detail. Why do edges look blocky? Strong lossy compression can introduce artifacts.
