Compress an image to 50 KB
50 KB is the usual allowance for a passport-style photograph on an application form, and a size a face still survives.
Where 50 KB comes from
- Examination and recruitment portals asking for a photograph, commonly 20 KB to 50 KB.
- Identity card and enrolment forms.
- Membership applications that print the photograph on a card.
What actually fits in 50 KB
Worked out from what this tool produces, not from a rule of thumb. Where a row says no, it says what to do instead.
| What you have | Fits in 50 KB? | What it takes |
|---|---|---|
| A passport-style headshot | Comfortably | Around 600px wide at good quality — enough for a printed card |
| A photo of a signed form | Tight | Around 800px; large print readable, small print not |
| An ID card photographed on a desk | Yes | Crop to the card first — the desk is costing you half the budget |
| A group photo or a landscape | It will fit | Detail goes first. Fine for a thumbnail, not for anything looked at closely |
Crop before you compress. A headshot that fills the frame fits in 50 KB at a size that still prints; the same face occupying a third of the frame does not, and no amount of quality searching recovers the difference.
If the form specifies dimensions as well as a size — 200×230 pixels is a common pairing — set the size here and check the dimensions afterwards; a form that rejects on either will reject on both.
Questions
- Will my face still look sharp at 50 KB?
- For a properly cropped headshot, yes. At around 600px wide the search typically settles on a quality in the 70s, which is well above where faces start to look blotchy.
- JPEG or WebP for a form upload?
- JPEG. WebP is genuinely smaller, but a portal that was written years ago may reject the format outright, and a rejected upload is worse than a slightly larger one.
A different limit?
Every one of these opens the same tool with a different number in the box. If the limit you were given is not here, open Compress Image and type it in.
