Expand JPG size: more KB or more pixels
Make a JPG bigger in KB or in pixels when a form says your file is too small.
A JPG that a form rejected as too small is exactly what this is for.

A bigger file (more KB) or a bigger picture (more pixels)? Open a JPG and choose: more KB raises quality until the file is inside your form's band, with the method stated and never a junk byte added.
Opens on “More KB” with a 20–50 KB band and your pixels unchanged. Pick a form's band from the chips, or type your own.
What this does to your file
On “More KB”, nothing about the picture changes: no canvas is added, no pixel is moved. The file is encoded again at a higher JPEG quality, found by a short search, until it lands inside the band. A JPEG at higher quality keeps more of the original detail, so the extra bytes are real image rather than filler.
If even quality 100 falls short, the page stops and says how far short, and offers a larger pixel size only as a choice you make. This product checks size, pixels and KB; the authority that set the rule checks everything else.

The awkward questions
Can you make a JPG bigger in KB without changing it?
Without changing the pixels, yes, within limits: the JPG is re-encoded at a higher quality, which keeps detail an earlier, harsher encode threw away, and the file grows. The width and height stay exactly as they are. The receipt after saving states the quality used and the size reached.
Why won't it reach 20 KB at 140 × 60?
Because a picture that small cannot hold that many bytes of real image, even at quality 100. When that happens the page says so with the numbers — the largest the file can be at that size — and offers the next pixel size that would reach the band, for notices where the pixel size is a preference rather than a rule.
Do you add fake data to pad the file?
No. No comment-segment padding, no trailing bytes. If quality cannot reach the minimum, the page stops and tells you, rather than producing a file that only looks right to an upload form.
What if my file is too big instead?
The same band works downwards: quality is lowered first, and only if that is not enough are the pixels reduced — and the receipt says so, because some notices fix the pixel size.
I meant a bigger picture, not a bigger file.
Choose “More pixels” at the top of the panel. That adds canvas around the photo — ten per cent a side to start — and every shape, size and fill on this site is available from there.
