How It Works

This tool draws your image onto an HTML5 canvas inside your browser, then re-encodes it as a JPEG at the quality level you choose. Reducing quality slightly lowers image detail in a way that's usually invisible to the eye, while significantly shrinking file size — useful for websites, email attachments, or saving storage space.

Frequently Asked Questions

How do I compress an image from MB to KB? Upload your image and move the Quality slider down — most photos in the 2-5 MB range can be compressed to under 200 KB while still looking sharp, which is exactly what most upload forms, job portals, and government websites require.

Can I compress a photo to a specific size like 50KB or 100KB? There's no direct "target size" input, but you can watch the live compressed size shown below the preview and adjust the quality slider until it's under the limit you need — for example, under 100 KB for exam form uploads.

Will compressing reduce image dimensions? No, only file size is affected — width and height stay the same unless you use the Image Resizer tool separately.

What's a good quality setting? 70–85% usually gives a strong balance between size and visual quality for most photos, typically shrinking a multi-MB photo down to a few hundred KB.

Does this support PNG transparency? The compressed output is saved as JPEG, which does not support transparency — use the Image Resizer tool if you need to keep a PNG format.
