To compress a photo to 100 KB, SafeResize saves it as a JPG of 100,000 bytes or less, which is under 100 KB whether a website counts 1 KB as 1,000 or 1,024 bytes.
| 100 KB in bytes | 100,000 bytes, or 102,400 bytes when 1 KB is counted as 1,024 bytes, as Windows does |
|---|---|
| 100 KB in MB | 0.1 MB, or 0.0977 MB as Windows counts |
| The photo you download | 100,000 bytes or less, so both counts accept it. Windows shows it as 97.7 KB or less. |
| Width and height | Up to 3200 pixels on the long side. They stay the same while the JPG quality can stay at 55% or more. Below that, the photo is made smaller so it does not turn blocky. |
| Official photo rules on SafeResize with 100 KB | As the largest file: Saudi Arabia Tourist e-Visa. |
Form says 50 KB to 100 KB? Open "More options" below and type 50 in "Must be at least".
100 KB is a common photo limit on online forms, and it leaves room for a clear, natural-looking photo.
The tool below opens with "Under 100 KB" chosen. SafeResize keeps the quality as high as it can while staying under the limit.
Some official rules use it: the Saudi Arabia Tourist e-Visa photo can be 5 KB to 100 KB, and the China Visa photo 40 KB to 120 KB. Others use different numbers, so always use the number on your own form.
A worked example: a phone photo of 3 MB is 3,072 KB. To get under 100 KB it has to keep only about 3% of its size (100 divided by 3,072). SafeResize lowers the JPG quality first. If the quality would drop far enough to make the picture blocky, it makes the picture smaller in pixels too, so you get a clean smaller picture and not a blocky big one.
Some websites count 100 KB as 100,000 bytes. A file Windows calls 98 KB can be 100,352 bytes, which is over. SafeResize stays under both counts.
At 100 KB many photos look nearly the same to the eye. The result screen shows the quality it used.
Yes. The new file is made from the picture only, so details like the GPS location are not copied.
