CBSE Photo Upload Error, How to Fix It
A CBSE upload, the board exam registration, the List of Candidates a school submits, or a private candidate form, is refusing the photograph or signature. CBSE images are very often scanned, and scanner settings produce files that are the wrong size or format, which is exactly what causes most of these errors and is quick to fix in your browser.

What a CBSE upload checks
CBSE uploads a student photograph and a signature, each checked for file size, format, and pixel dimensions. The figures are commonly cited and change between sessions, so read the exact ones in the current circular and on the upload screen, but they are usually a small band for each image as a JPEG at a set pixel size.
Because schools upload many students through the List of Candidates, the same wrong setting can fail a whole batch. Getting one file right shows the correct size and format to use for the rest.
Scanned photos and signatures
Most CBSE images come from a scanner, and scanners default to high resolution and sometimes to PNG or TIFF, which produces a file that is far too large or in a format the form does not accept. That is the usual reason a scanned photo or signature is refused.
Drop the scan into the tool above, save it as a true JPEG, and set the size to the form's limit in the same step, so a heavy scan becomes a light, valid file. Scan or photograph the photo and signature straight on, in even light, and crop close before you upload, so the image is clean as well as correctly sized.
Get the file inside the size window
Set the limit the circular lists in the tool and compress the image to land just inside it, staying above any minimum. If both a photo and a signature are required, do each separately against its own limit and upload each to its matching field.
If a scanned signature is faint or grey, re-scan or re-photograph it in better light rather than pushing a poor image through, since a high-contrast black-on-white signature both converts cleanly and passes review.

Format and dimensions
If the size is right and it still fails, check the format. CBSE expects JPEG, and a scan saved as PNG or TIFF, or a file renamed to .jpg, is read as invalid. Re-save it as a true JPEG and try again.
Then check the dimensions, since CBSE specifies pixel sizes for the photo and signature, and resize to the exact pixels if the size and format are both already right. A scan is often the wrong shape until it is cropped and resized.
Private candidates uploading their own photo
Private and second-chance candidates upload their own photograph and signature rather than going through a school, and they hit these errors most, because the images come from a phone or an old scan. The rules are the same as for a school upload: a JPEG photo and signature at the size and pixel dimensions the form lists.
Take a fresh photo against a plain light wall rather than reusing an old one, save it as a JPEG, and compress it under the form's limit. Capture the signature in dark ink on white paper, crop it close, and save it as a small JPEG. Clean, correctly-sized files avoid almost every private-candidate upload problem.
When the upload will not complete
If both files are correct and the upload still fails, the cause is usually the connection or the portal rather than the file. CBSE upload windows are busy, especially for schools submitting many students at once, so use a stable network and a current desktop browser, and avoid the final hours of the window.
Clearing the cache, turning off extensions, or trying a different browser also resolves uploads that stall for no clear reason. If the portal itself is throwing errors, the only fix is to wait for the load to drop or to contact CBSE, which a file tool cannot do for you.
When it is the photo, not the file
If the upload succeeds but the photo is rejected, the problem is appearance: a tilted or shadowed scan, a busy background, or a face that is unclear. Those need a clean recapture, not a new file. Photograph the student against a plain light wall in even light, or scan a proper passport photo straight on.
Everything here runs inside your browser on your own device. The student's photo and signature are never uploaded to a server to be processed, so they stay private until the file is submitted to CBSE.

Fix by the exact error
Most rejections are mechanical, the file is too big, too small, the wrong pixels, or the wrong type. Pick the message your form showed.
