Why an online form rejects your photo (and how to fix it)
The usual reasons a job, exam or ID form refuses a photo or signature: file size, pixel size, format, background and blur, with the fix for each.
The file is too big
Forms set a maximum such as 20 KB or 50 KB. Set that number as the maximum here; the file is never over it.
The pixel size is wrong
Some forms check width and height exactly (for example 200 × 230 px). Enter both; the output always has exactly that size.
The file is too small
A few forms also set a minimum (for example 10 KB) to stop blank or tiny images. Set the minimum; if your photo can’t reach it at full quality, use a larger pixel size.
The format is wrong
Most forms want JPG (.jpg or .jpeg). Photos from iPhones are often HEIC, which forms refuse. This tool always saves JPG unless you choose PNG for a signature.
The background or face is unclear
Stand against a plain light wall, face the light, and keep your face in the guide oval. Shadows and busy backgrounds look worse when squeezed into a few KB.
The rule changed
Organisations change their rules between advertisements. Always check the size rule printed in your own advertisement or on the portal.
Questions
Why does the form say my photo is too large when it looks small?
Forms check the file size in KB, not how big the photo looks on screen. A phone photo is usually 2–5 MB, so set the form’s maximum KB in PhotoSize and download the new file, which is never over that limit.
Why is my photo rejected even though it is under the KB limit?
The form is probably also checking the pixel size, the minimum KB or the format. Enter the exact width and height, add the minimum KB if the form has one, and make sure the file ends in .jpg.
Can a form reject a photo for being too small?
Yes, some forms set a minimum such as 10 KB. Enter it as the minimum KB; if the photo can’t reach it, use a larger pixel size so there is more detail to store.
