What happens if I upload the wrong file type or it’s too big?
CertNudge may reject a file if it is larger than 5 MB, uses an unsupported format or fails file-type validation. Check the file and create a suitable copy before attempting the upload again.
Upload requirements
PDF, JPEG/JPG, PNG and HEIC
The file must use one of the formats supported by the certificate and evidence-upload workflow.
5 MB per file
Each individual file must be no larger than 5 MB.
Why might a file be rejected?
The file is too large
A file exceeding the 5 MB limit cannot be accepted through the main certificate workflow.
The format is unsupported
Files such as Word documents, spreadsheets, ZIP archives and other unsupported formats will be rejected.
The actual file type does not match
CertNudge validates the file type on the server as well as checking its name and extension. Renaming an unsupported file to end in .pdf or .jpg does not convert it.
The file cannot be processed
A damaged, incomplete or otherwise unreadable file may also fail the upload checks.
How to fix the problem
Check the file size and format
Confirm that the file is PDF, JPEG/JPG, PNG or HEIC and no larger than 5 MB.
Export or scan it again
Use trusted settings on your computer, scanner or mobile device to create a supported, smaller copy.
Check readability and completeness
Make sure every required page remains present and that names, dates, results and other important details are clear.
Try the upload again
Select the revised file and repeat the upload. Successful processing cannot be assumed until CertNudge confirms that the record was saved.
Avoid unfamiliar online compression services
Certificate evidence may contain sensitive property information. Prefer trusted scanning and export tools available on your own device.
Validation does not verify the certificate
Passing the upload checks means only that the file meets the supported technical requirements. CertNudge does not authenticate the document, verify its contents or determine legal compliance.
Still unable to upload?
Email support@certnudge.co.uk with the file type, approximate size and error shown. Do not attach the certificate file, passwords or tenant personal data.
