Increase image size in KB, to pass the minimum.
Your photo stays on this device. Nothing is uploaded.
Pick the size
You can change it after adding the photo.
Some forms reject files that are too small. Set the minimum, and FormPic raises the JPEG quality, then adds pixels, until the file is big enough.

How do I increase an image's size in KB?
Add the image and type the form's minimum into Min file size; it starts at 20 KB. FormPic first raises the JPEG quality, up to 100%. If the file is still too small, press Enlarge to fit and it adds pixels in proportion, without stretching, until the file passes. Forms with minimums include UPSC (20 KB), RRB signatures (30 KB), the UK passport digital photo (50 KB) and Australian visas (70 KB).

Why files come out too small
- Signatures and documents on white paper have little detail, so JPEG stores them in very few bytes.
- Small pixel sizes, like 140 × 60 or 200 × 230, cap how big the file can get.
- Heavily compressed originals, such as photos forwarded on chat apps, have lost detail.
Adding pixels doesn't add real detail; it lets the file meet the form's minimum. Starting from the original camera photo or a fresh scan always looks better.

Frequently asked questions
Does increasing KB make the photo look better?
No. It makes the file bigger so it passes the form's check. Higher JPEG quality keeps a little more detail; extra pixels don't add any.
Can I increase the size without changing pixels?
Yes, up to a point: FormPic raises the JPEG quality to 100% first. Past that, only more pixels make the file bigger.
Why not just add a border or noise?
Forms check that the photo shows you clearly; borders and noise can get it rejected. FormPic only raises quality and resizes.
Will PNG make the file bigger?
Usually much bigger, but most forms that set a minimum also require JPEG. Stay on JPEG unless the form accepts PNG.
Is my image uploaded?
No. FormPic works 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.
