To compress a photo to 500 KB, SafeResize saves it as a JPG of 500,000 bytes or less, which is under 500 KB whether a website counts 1 KB as 1,000 or 1,024 bytes.
| 500 KB in bytes | 500,000 bytes, or 512,000 bytes when 1 KB is counted as 1,024 bytes, as Windows does |
|---|---|
| 500 KB in MB | 0.5 MB, or 0.488 MB as Windows counts |
| The photo you download | 500,000 bytes or less, so both counts accept it. Windows shows it as 488.3 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 500 KB | As the largest file: Rwanda Visa, South Korea Passport, South Korea Visa / e-Visa and Tanzania e-Visa. |
500 KB is a generous limit: enough for a sharp photo with fine detail. Photos straight from a phone are often 2 to 5 MB, so reaching 500 KB means dropping about 75% to 90% of the size, which is a gentle cut compared with going down to 50 KB.
The tool below opens with "Under 500 KB" chosen. SafeResize keeps the quality as high as it can while staying under the limit, and only makes the picture smaller in pixels if it has to.
About, yes. Half a megabyte is 500 KB by the metric count and 512 KB on Windows. SafeResize keeps the file under 500,000 bytes, so it passes both.
Not unless they have to. If your photo already fits, the width and height stay the same and only the JPG quality goes down. Very large photos are first reduced to 3200 pixels on the longest side.
The tool keeps the file under the limit, not exactly on it. If a form also says "at least" some size, open "More options" and fill in "Must be at least".
