Pick the size
You can change it after adding the photo.
Forms with a 10–20 KB range reject files that are too small as well as too big. FormPic keeps under 20 KB and lifts small files over 10 KB.

How do I get an image between 10 KB and 20 KB?
Add the image; both limits are already set. FormPic picks the highest JPEG quality under 20 KB, and if the file is under 10 KB even at full quality, Enlarge to fit adds pixels until it passes. SSC (CGL, CHSL, MTS, GD) and IBPS and SBI all ask for signatures between 10 KB and 20 KB.

Staying inside 10–20 KB
- Signatures on white often land under 10 KB. That's the usual failure, not being too big.
- Set the form's pixel size first; a bigger pixel size raises the file size.
- If the form fixes the pixels, FormPic raises JPEG quality before adding pixels.
If a form gives both a pixel size and a file size, set the pixels first. FormPic then fits the file size without changing them.
How to resize an image to 10–20 KB
- Add the imageAdd your signature or photo. The 10 KB minimum and 20 KB maximum are already on.
- Crop itDrag the crop close around the signature or face, then type the form's pixel size if it gives one.
- Read the statusFormPic shows the quality it picked. If it says Under the 10 KB minimum, press Enlarge to fit.
- DownloadThe Download button shows a size between 10 and 20 KB.
Frequently asked questions
Why does FormPic count 10 KB as 10,240 bytes?
For a minimum, the stricter reading is 1,024 bytes per KB, so 10 KB becomes 10,240 bytes. For the maximum, the stricter reading is 1,000, so 20 KB means under 20,000 bytes. The file passes either way.
Enlarge to fit changed my pixel size. Is that allowed?
For SSC, which gives the signature in centimetres as an approximate size, yes. IBPS and SBI call 140 × 60 px preferred, not fixed. If a form insists on exact pixels, raise the size of the signature on paper instead.
Is my image uploaded?
No. FormPic compresses it inside your browser.

Need a size that isn't here?
FormPic is made by one developer, Devanshu Verma. If your form asks for a photo size FormPic doesn't have yet, something didn't work, or you have an idea for a feature, send a message through the contact form on his portfolio. Size requests decide which presets come next.
For a new size, it helps to mention the form or country, the size it asks for (in mm or pixels), and any file size limit.
