How to compress images to a KB limit

Select up to 12 JPEG, PNG, or static WebP images.
Choose a KB limit that applies to each image.
Download one result or a ZIP of successful images.

A limit for each image

We measure the actual encoded file before offering it. An unreachable target is reported as a failure.

Review and download

Compare the original and result, then download a single file or a ZIP of successful images. The ZIP total can exceed one image’s KB limit.

Free and local

No registration is needed. Images stay in your browser and are never uploaded for compression.

Frequently asked questions

Is my image uploaded?

No. The image is decoded and encoded in your browser. This site does not receive it.

Can every image meet any limit?

No. If keeping the dimensions makes the limit impossible, allow resizing or raise the limit. We never offer an oversized result as success.

What if my image is already below the limit?

You can download the original file unchanged. Its metadata, including possible EXIF data, remains in that file.

Which files and batch sizes are supported?

Select up to 12 JPG, PNG or static WebP images, up to 50 MiB total. Each file must be at most 20 MiB, 40 megapixels and 16,384 pixels on either side.

How does the KB limit apply to a batch?

Each successful image meets the same limit. The ZIP contains those files and can be larger than the limit for one image. Here, 1 KB means 1,000 bytes.

Does compression keep EXIF metadata?

Re-encoded results do not keep EXIF; orientation is applied to the pixels. An original file returned unchanged keeps its metadata. Check the result before sharing.

A smaller file, with a real limit

Set a maximum in KB and we check the actual encoded file before offering it. JPEG and WebP try quality first, then dimensions. PNG keeps transparency and uses dimensions when needed.
