When you need to increase a photo's size

Most people compress photos to get under a limit — but many Indian exam and job portals also set a minimumfile size. A common rule is a photo of "20 KB to 50 KB", so an image that is only 8 KB is rejected for being too small. This tool does the opposite of a compressor: it increases your image to at least the KB you need.

It keeps your picture at full quality and simply tops the file up to the target, so the photo looks exactly the same and uploads as a normal JPG. If you need to go the other way, use our Image Compressor or resize an image in KB to a maximum instead.

Frequently asked questions

Why would I need to increase an image's size in KB?
Some exam and job portals set a MINIMUM file size as well as a maximum — for example, a photo must be between 20 KB and 50 KB. If your image is below the minimum, the form rejects it, so you need to increase its size to fit the range.
How do I increase an image to a minimum KB?
Set the minimum KB you need above, then upload your photo. The tool re-saves it at top quality (enlarging it if necessary) and tops up the file to your target, then lets you download it — all in your browser.
Does increasing the file size reduce quality?
No. The tool keeps your image at the highest quality and only adds harmless padding to reach the size — the picture looks identical, it just weighs more on disk so it passes the minimum-size check.
Is the image still a normal JPG I can upload?
Yes. The result is a standard JPG that opens and uploads everywhere; the extra bytes are ignored by image viewers and form checkers, which only read the file size.
Is it free and private?
Completely free with no sign-up, and the image is processed entirely on your device — it is never uploaded to a server.
