Estimated JPG file size for Sarathi driving licence uploads
Estimated from sizes measured with sharp 0.35.5 / libvips 8.18.7 on public-domain sample images (31 October 2026), interpolated to each target size. Your own scan can land 30-50% either side, which is why the tool measures the real file.
| Upload | Pixel size used | Quality 60 | Quality 75 | Quality 85 | Quality 95 | Limit |
|---|---|---|---|---|---|---|
| Photo | 420 × 525 px | 24.4 KB | 31.4 KB | 41.4 KB | 72.5 KB | 10 KB–20 KB |
| Signature | 256 × 64 px | 1.4 KB | 1.8 KB | 2.6 KB | 4.8 KB | 10 KB–20 KB |
Will the Sarathi driving licence photo fit the limit?
A portrait for the Sarathi driving licence photo at 420 × 525 px is about 24.4 KB even at JPG quality 60, over the 20 KB limit. With the size fixed by the preset, the tool keeps lowering JPG quality (down to quality 5) and reports the smallest file it reaches; if that is still too big, clear the width and height in the panel so it can scale the picture down.
An ink-on-white scan for the Sarathi driving licence signature at 256 × 64 px comes to about 2.6 KB at JPG quality 85 and 4.8 KB even at quality 95, under the 10 KB minimum, so raise the pixel size if the form allows it or let the tool pad the file up to 10 KB (tick the padding option under "Fit, background and padding"; it is off by default).
