Frequently asked questions
How do I increase a photo from 10 KB to 50 KB?
Drop the photo here, choose 50 KB and download. ShrinkTo re-saves it at top quality and, if it is still too small, adds harmless padding data inside the JPEG so it reaches exactly the size you picked.
Does increasing the KB change how the photo looks?
No. The pixels are the same; the extra bytes are a comment block inside the JPEG file that every viewer and upload form ignores.
Why would a form reject a small photo?
Many exam, job and government portals set a size range such as 20-50 KB to make sure photos aren't overly compressed. This tool gets you inside the range in one step.
Are my files uploaded to a server?
No. Everything runs locally in your browser - your files never leave your device. You can confirm this by opening your browser's Network tab while you use the tool.
Is it free? Do I need to sign up?
It's completely free with no signup, no email, and no limits. Because the work happens on your own device, there's no server cost and nothing to charge for.
