Which forms want photo and signature in one image?
It depends entirely on the form. Most large exam portals, including many Indian recruitment exams, ask for the photo and signature as two separate uploads with their own sizes. A combined image is mostly requested by some recruitment, admission, scholarship and registration forms, often in a line such as "upload photograph with signature below it, 20–50 KB".
Before you make one, read the notification or the help text next to the upload box. Check four things: whether a combined image is really wanted, whether the signature goes below or beside the photo, the pixel size or width, and the KB range. If separate uploads are required, use the exam photo resizer and signature resizer instead.
Getting a clean signature
The trim and whitening work best when the signature is clearly darker than the paper. A few habits help:
- Sign with a black or dark blue pen on plain white paper, with no lines or pattern.
- Photograph it in daylight or under a bright, even lamp, and avoid your phone's shadow falling across the page.
- Hold the phone parallel to the paper so the signature is not slanted or stretched.
- Leave some margin around the signature; the tool trims it for you.
If trimming cuts into a faint stroke, turn off "Auto-trim signature whitespace" and crop the scan yourself. If whitening makes thin strokes too pale, switch it off. Most forms want the signature large and legible, so raise the signature height slider if it looks small.
Width, border and KB range
The output width sets the size of the whole image, and the height follows from your photo's shape. 300 px wide suits most "photo with signature" boxes. Choose a custom width if your form gives exact pixels. A thin black border makes the edges clear on a white page; some forms prefer none.
The default range of 20–50 KB matches many forms, but use whatever yours states. The range is checked so that the file passes whether the portal counts 1 KB as 1,000 or 1,024 bytes. If you need a date under the photo, tick "Add name and date line". For a name and date on a single photo, use name and date on photo.
The joiner does not edit the photo itself, so start with one that already meets the form's photo rules: recent, face clearly visible, plain light background and no filters. Crop it to passport shape before adding it, because the photo's proportions decide the height of the combined image.
