Compress an image to a target size

How it works

Many forms and job portals reject photos over a size limit. Set the maximum size in KB and this tool lowers the JPEG quality step by step, then scales the image down only if it must, until the file fits. It all happens in your browser, so your photo is never sent anywhere.

Typical size limits

Limits vary by site, so check the instructions first. Photo uploads for forms and ID applications often ask for somewhere between 20 KB and 200 KB, and some also require exact pixel dimensions or a specific format. If dimensions matter, resize first with the image resizer, then compress.

Tips for getting under the limit

• Photos compress far better than screenshots or images with lots of fine text.
• If the result looks too soft, raise the limit a little. A few extra KB can noticeably improve quality.
• PNG images are saved as JPEG, and any transparent areas become white.
• Cropping out empty background before compressing lowers the size without hurting the subject.

Common questions

How do I compress an image to under 100 KB?

Choose the image, enter 100 as the maximum size, and press Compress image. The result shows the new file size.

Does this reduce image quality?

Slightly. The tool keeps the highest quality that still fits your limit. Very small limits may also reduce the dimensions.

Is my image uploaded to a server?

No. The image is processed by your browser and never leaves your device.

Why did the image also get smaller in dimensions?

If lowering quality alone could not reach your limit, the tool scales the image down in steps until it fits. A smaller limit means a smaller picture.
