Making a face photo look good at 30KB
At 30KB a full phone photo comes out about 340×450 pixels — plenty for the small preview box on an application form. The tool shrinks the dimensions first, so the face stays clean instead of turning blocky.
A plain white or light-blue background helps a lot: flat colour costs almost nothing to store, leaving more of the 30KB for your face.
We tested it: three phone photos to 30 KB
We ran three real 12-megapixel phone photos through this page in Chrome on an ordinary laptop. Here's exactly what came out:
| Photo | Original | Result | Dimensions | Time |
|---|---|---|---|---|
| Pixel 2 photo | 4.16 MB | 29.3 KB | 339×453 | 0.5 s |
| iPhone 6 Plus photo | 3.51 MB | 29.6 KB | 339×453 | 0.3 s |
| Galaxy S7 Edge photo | 3.97 MB | 28.7 KB | 453×339 | 0.5 s |
At 30 KB, a full phone photo becomes about 340×450 pixels, enough for a sharp face in an application preview box. 25 KB gave 310×413.
Two results were just over 30,000 bytes (but under 30 KB counted as 1,024 bytes per KB). For forms that count 1,000 bytes, type 28 as a custom size.
Signatures at 30KB
Sign in dark ink on plain white paper, photograph it in good light, and crop tightly around the signature before compressing. A tight crop keeps the strokes sharp even at small sizes.
Check the form's other rules
- Minimum size: some forms also require at least 10KB or 20KB — the result shows the exact size.
- Pixel dimensions: if the form asks for something like 200×230 pixels, crop to that shape first.
- Format: forms almost always want JPG, which is what this tool produces.
Frequently asked questions
Can I compress a photo from 5MB to 30KB?
Yes. Large phone photos are resized and recompressed in one step, usually in under a second.
The form says under 30KB but rejects my file — why?
Some sites count 1KB as 1,000 bytes. Choose 25KB or type a custom value like 28 to leave a margin.
Is my photo stored anywhere?
No. It's processed in your browser and never uploaded.
