Upload limits are usually stated in kilobytes, not quality settings, so a compressor that works toward a KB target is more directly useful than one that only offers a vague quality slider.
A form or portal enforces a strict size cap
Government forms, job applications, and photo ID uploads often reject anything over a set KB limit — compressing to that target gets it accepted.
A photo needs to load faster on a website
Smaller image files mean quicker page loads, which matters for anyone publishing images online.
Storage or attachment limits are tight
Email attachment caps and limited cloud storage both benefit from images that take up less space without extra software.
How it works
Upload
Add the image you want to shrink. Nothing is sent anywhere at this step.
Set a target
Enter the target size in KB you need the final image to be under.
Compress
The image is processed locally in your browser toward that target size.
Download
Save the compressed image. Your original file is untouched.
Key features
Exact KB target
Enter a specific size in KB rather than guessing at a quality percentage.
JPG and PNG support
Compress common image formats without needing to convert them first.
Runs in your browser
Compression happens locally on your device — the image is never uploaded to a server.
No sign-up
Open the tool and start compressing — no account, no email, no waiting.
Free
Compress as many images as you need, with no watermark added to the result.

Frequently asked questions
Can I set an exact target file size?
Yes, enter a target size in KB and the tool compresses toward that target.
What happens if the target size cannot be reached?
The compressor keeps the smallest result it managed to produce and tells you the actual size reached, rather than silently failing.
Is my image uploaded anywhere?
No. The whole compression loop runs on-device — nothing is sent to a server.
