Resize image to 15 KB, the safe middle.

You can change it after adding the photo.
Aim for 15 KB when a form asks for 10 to 20 KB: it clears the minimum and stays well under the maximum. FormPic finds the best quality that fits.

How do I resize an image to 15 KB?
Add the image, keep Max file size on 15 KB, and download. FormPic picks the highest JPEG quality under 15 KB and shows the final size on the Download button. 15 KB isn't a limit itself in the forms checked here, but it's the middle of the 10–20 KB range SSC, IBPS and SBI use for signatures, so a 15 KB file passes those checks with room either side.

Hitting 15 KB cleanly
- Crop close. A signature strip or head-and-shoulders crop leaves the bytes for detail.
- Type the form's pixel size first, then let FormPic fit the file size.
- If the file lands well under 10 KB, it's too small for a 10–20 KB form: press Enlarge to fit or set a 10 KB minimum.
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.

Frequently asked questions
Why aim for 15 KB instead of 20 KB?
Portals count a KB as either 1,000 or 1,024 bytes, and some re-check the file after upload. Landing in the middle of a 10–20 KB range passes every reading.
My signature is only 6 KB. How do I reach 15 KB?
Type 10 into Min file size, or use the 10–20 KB range page. FormPic raises the quality, and Enlarge to fit adds pixels if needed.
Why does FormPic show 14.6 KB instead of 15 KB?
Some portals count a KB as 1,000 bytes and others as 1,024. FormPic keeps the file under 15,000 bytes so it passes either check, and shows sizes in 1,024-byte units, so a file right at the limit reads 14.6 KB.
Is my photo uploaded to compress it?
No. FormPic compresses the photo inside your browser, so it never leaves your device. That also makes it fast: there's no upload or download wait.

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.
