What Pixel Size Fits in 20 KB?
A photo's file size depends on how many pixels it has and how much detail they hold. As a rough guide, a detailed photo saved as a JPG takes about 0.2 bytes per pixel at balanced quality. The table shows sizes that usually fit in 20 KB. Flat backgrounds and soft light compress better, so real results vary.
| Shape | Approximate size that fits |
|---|---|
| Passport-style portrait (4:5) | 270 × 340 px |
| Square (1:1) | 310 × 310 px |
| Landscape (4:3) | 350 × 260 px |
Tips for Best Results
- Crop tightly first. Fewer, flatter pixels are the easiest way to reach a tiny size.
- Start from a plain background and even light; noise and texture eat the size budget.
- For a photo of a face, do not go below about 150 px wide or details turn to mush.
Limits and Things to Know
- The result is normally just under 20 KB, not exactly equal to it.
- Very detailed photos need lower quality or fewer pixels to fit small targets.
- Transparent areas turn white when the picture is saved as a JPG.
