Ecom Image Optimizer
Compress JPEG
Shrink JPG files to a target size: sharp images, far smaller files.
Last updated
Most product photos are several times larger than they need to be. A 4 MB camera JPG carries detail no shopper will ever see on a 1200-pixel-wide product page, and every unnecessary kilobyte slows the page down.
This tool compresses to a target file size rather than a vague quality slider, so you can say "every image under 200 KB" and get exactly that. Adjust the target in the left panel, which is already open on File size.
How to use it
- 1Drop your JPG files onto the tool above.
- 2Set your target file size in the left panel (200 KB is a good default for product images).
- 3Each image is compressed to hit that budget automatically.
- 4Download the compressed files individually or as a ZIP.
Frequently asked questions
How much can I compress a JPEG without losing quality?
For typical product photography, 70–90% smaller is achievable with no difference visible at normal viewing size. The biggest wins usually come from resizing to the dimensions you actually display, then compressing.
What file size should product images be?
Under 200 KB is a good target for a standard product photo, and under 500 KB for a large hero banner. Below about 100 KB you may start to see artefacts on detailed textures.
Is JPEG compression reversible?
No. JPEG is lossy, so discarded detail cannot be recovered. Always keep your original files and compress a copy.
Why does compressing again make images look worse?
Each JPEG save re-compresses the image and adds artefacts on top of the previous ones. Compress once from the highest-quality original rather than repeatedly from an already-compressed file.
Can I compress hundreds of images at once?
Yes. Up to 100 files per batch, each up to 50 MB, downloadable together as a ZIP.
