How do I compress a photo to 50 KB?

To compress a photo to 50 KB, SafeResize saves it as a JPG of 50,000 bytes or less, which is under 50 KB whether a website counts 1 KB as 1,000 or 1,024 bytes.

50 KB in bytes50,000 bytes, or 51,200 bytes when 1 KB is counted as 1,024 bytes, as Windows does
50 KB in MB0.05 MB, or 0.0488 MB as Windows counts
The photo you download50,000 bytes or less, so both counts accept it. Windows shows it as 48.8 KB or less.
Width and heightUp 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 50 KBAs the smallest file: UK Passport, UK ETA and UK Visa.

Before you start

Form says at least 50 KB? Increase photo size in KB. This page makes files under 50 KB.

50 KB is a common limit for applicant photos. A phone photo is usually 2 to 5 MB, so it has to lose about 98% of its size.

The tool below opens with "Under 50 KB" chosen. Add your photo and download the smaller copy. Your original stays as it is.

Tips

Careful: 50 KB is sometimes a minimum

Not every 50 KB is a limit on how big the file can be. On SafeResize, the UK ETA, UK Passport and UK Visa photo rules say the file must be at least 50 KB, so a photo made smaller than that would be refused.

Read the form. "Up to 50 KB", "under 50 KB" and "maximum 50 KB" mean the file must not be bigger. "At least 50 KB" or "minimum 50 KB" means it must not be smaller. For a minimum, use the page for increasing a photo size in KB.

Questions and answers

Is 50 KB enough for a passport photo?

For most forms, yes. But some official rules set a minimum. The US visa photo, for example, needs about 53 KB or more at 600 × 600 pixels, so use the US visa page for it.

Why does my computer show 49 KB and my phone 50 KB?

Windows counts 1 KB as 1,024 bytes and phones count 1,000. SafeResize keeps the file under the limit both ways.

Can I make several photos smaller at once?

Not yet. Do them one at a time; each takes a few seconds.
