ImmiAccount will not accept your document

The most common cause is not size

If ImmiAccount refuses a document that is comfortably under the limit, the usual reason is that the PDF is encrypted or secured — and you almost certainly did not encrypt it yourself.

The Department's own guidance says it directly:

"The ImmiAccount system does not accept encrypted or secured PDF files. If you are unable to attach document, check that it is not encrypted. This often occurs with documents downloaded directly from the website."

That last sentence is worth reading twice. Forms downloaded from the Home Affairs website are frequently secured, and the Home Affairs system then refuses them.

The Department's suggested fix is to print the document and scan a new copy.

You do not need a printer. Removing the protection from the file does the same job in a few seconds, and gives you a cleaner document than a rescan — no skew, no grey paper, no extra megabytes. That is what the tool at the top of this page is for.

Why you cannot tell by looking

A "secured" PDF is not the same as a password-protected one. It opens normally. Nothing on screen indicates anything is different. The restriction sits in the file's permissions — it may forbid editing, copying or modification — and ImmiAccount reads that and stops.

This is also why the failure is so confusing: the file opens on your machine, it is the right size, it is the right format, and the upload still will not go.

Bank statements are the other common source. Many banks issue statements with permissions set, and Australian visa applications ask for a lot of bank statements.

The real limits

Notice the lower bound on photographs. ImmiAccount requires a photo to be at least 70 KB, which is unusual — almost every other portal specifies only a maximum.

Every guide on the internet tells you to compress a photo as small as it will go. Follow that advice here and your photograph is rejected for being too small, with no obvious explanation. Aim for the middle of the range.

Accepted formats

.bmp · .dcm · .doc · .docx · .dot · .gif · .jpg · .png · .pdf · .ppt · .pptx · .rft · .txt · .xls · .xlsx

Two things to notice.

.jpg is listed; .jpeg is not. They are the same format, and most software treats the extensions interchangeably, but a portal checking the string will not. Re-save as .jpg rather than simply renaming the file.

Compressed archives are not on the list. If you have read that "compressed files are not accepted", that means ZIP archives — not compressed PDFs. Reducing the size of a PDF is fine, expected, and often necessary. Putting several files into a .zip is what will be refused. The two things are easy to confuse and the confusion points people in exactly the wrong direction.

The document cap is a reason to merge

Sixty documents per person sounds generous until you assemble a partner visa application. Relationship evidence, joint accounts, travel history, statutory declarations, photographs — people run out.

The practical answer is to combine before you upload: twelve months of payslips as one PDF rather than twelve, a year of bank statements as one file rather than twelve. It respects the cap, it is easier for a case officer to read in order, and it is the thing most applicants realise too late.

Merging PDFs takes a few seconds. Do it before you start attaching, not after you hit the limit.

In order, when an upload fails

1. Check whether it is encrypted. This is the most common cause and the least

obvious. If it came from a government website or a bank, assume it is.

1. Check the size — under 5 MB for documents, and for photographs between 70 KB

and 3.5 MB.

1. Check the extension — .jpg, not .jpeg.
2. Check it is not a .zip.
3. Only then start suspecting your connection or the site.

One thing worth knowing before you submit

The Department states that you cannot access your supporting documents from ImmiAccount after uploading, and that you cannot remove a document after the application is submitted. An incorrect attachment requires a separate notification form to correct.

So keep your own copies of everything, and check each file before it goes — not afterwards.
