Questions
How does it reach an exact size?
It tries different quality levels until the photo fits under your limit while keeping as much detail as possible. If the limit is very small, it also makes the photo slightly smaller in pixels.
The form says between 20 KB and 50 KB. What should I type?
Type the maximum, 50 KB. The result will be just under it, which is well above the minimum.
Which format should I use for a form?
JPG. Almost every form accepts it, and it gives the smallest files for photos.
Does it change the photo’s width and height?
Only when needed to reach the size. You can turn off “Allow smaller dimensions”, but very small limits may then be impossible to reach.
