Why a form says the file is too small
Some forms set a smallest file size as well as a largest, for example at least 20 KB, to stop empty or tiny pictures. A photo that was compressed before, or a small crop, can fall under it.
| How the tool adds KB | What changes |
|---|---|
| Higher quality | More fine detail is kept; the photo looks the same or better |
| More pixels | Only if the quality alone is not enough: the photo is enlarged smoothly |
| Nothing hidden | No padding or hidden data: the file is a normal photo |
Does a larger file mean a better photo?
No. A higher quality cannot bring back detail that was lost before, and enlarging makes a photo softer. It only makes the file meet the minimum.
Both a minimum and a maximum
If the form asks for, say, 20 to 50 KB, set “At least” to 20 KB. If the file comes out over 50 KB, switch to “At most” and type 50 KB: the tool keeps it just under.
When the photo itself is the problem
Compression makes a photo lighter, not better: it cannot fix a blurry, dark or badly framed picture. If the photo is for a CV, a profile or an application and you have no good one, a professional headshot made from a few selfies gives you one.
