'There is a problem with this file error – please try a different PDF creator'.

Although we accept a maximum file size of up to 1GB, if you've received the error message above, this means there is content in your file that'll need to be compressed.

Please either compress your whole file(s) and reupload the amended file(s) to the website. If you do not have design software then we recommend using https://smallpdf.com/compress-pdf.

Or, in some cases you can compress the individual images in your file.

Should this not help, then please split the document into multiple files to upload and combine on site.

Please note, we advise for files which include images/graphics, have their image 'layers' flattened beforehand, along with embedding any text/fonts in the file too.

To ‘flatten’ your image, is to flatten them down into one single layer. Flattening is also referred to as saving as an image, which allows the the file to upload an process smoothly.

'Embedding' a font means to save the font information within the document (you would do this if you've downloaded a a unique font from an Online package etc.). Alternatively, you can 'outline' your text content and convert it to an image within your document.
