Steps
- Sign on clean white paper with a dark pen, a bit larger than usual.
- Photograph it from straight above in daylight.
- Choose the image above and select the size your form asks for.
- Adjust the cleaning slider until the background is white and the strokes are solid.
- Download the JPG and upload it.
Common signature requirements
Job and admission portals in Pakistan usually ask for a wide, short signature image – for example around 300×80 or 140×60 pixels, with a limit of 10–30 KB. Some forms require the signature in black ink only. Always check the portal's instructions and use the custom size option if they differ from the presets.
Why your signature gets rejected
- The file is above the KB limit or the wrong format (most need JPG).
- The background is grey or shadowed instead of white.
- The signature is too small within the frame because of empty margins – automatic cropping fixes this.
- The image is rotated; make sure the photo is upright before choosing it.
Next, resize your photo or compress other documents with the image compressor.
Frequently asked questions
How do I scan my signature with a phone?
Sign on plain white paper with a black or dark blue pen, place it under good light without shadows, and take a photo from directly above. The tool will whiten the paper and cut away the empty margins.
My signature looks faint after cleaning. What can I do?
Move the background-cleaning slider to the right so lighter strokes are kept, or sign again with a thicker pen.
Why does the signature appear grey or with a shadow?
Shadows on the paper can be read as ink. Move the slider to the left until the background is clean, or retake the photo in better light.
Is my signature stored anywhere?
No. Everything is processed in your browser and nothing is uploaded or saved by this website.
