ImmiAccount Attachments: 5 MB Limit and File Rules

From the Home Affairs ImmiAccount help page Attach documents (checked on 10 October 2026).

• Visa applications: files up to 5 MB each, with the extensions bmp, dcm, doc, docx, dot, gif, jpg, pdf, png, ppt, pptx, rtf, txt, xls or xlsx.
• Compressed files (such as zip) and encrypted PDF files cannot be accepted.
• For documents with more than one page, provide the pages in a single PDF.
• Scan each document separately, include both sides, and scan in colour if the original is in colour.
• Citizenship applications: images are preferred as jpg, with the file size limited to 500 KB.
• There is a limit to the number of files per applicant, and attached files cannot be deleted.

1. 1

   Unlock encrypted statements

   Bank and super statements often arrive as password protected PDFs, which ImmiAccount rejects. If you know the password, save an unprotected copy with Unlock PDF.

2. 2

   One PDF per document

   Combine the pages of each document, both sides included, into one PDF with JPG to PDF, or join existing PDFs with Merge PDF. Keep different documents in separate files.

3. 3

   Stay under 5 MB

   If a combined PDF is too big, shrink the page images first with Compress Image in Target size mode, about 400 KB per page, then combine them again.

4. 4

   Citizenship images under 500 KB

   For citizenship applications, open Compress Image, choose Target size and click the 500 KB preset. The tool keeps the best quality that fits and outputs a jpg, as the Department prefers.

The same help page says every document that is not in English must come with an English translation, provided together with the original. Scan or photograph both, and where possible scan the original document rather than a photocopy. Combining the original and its translation into one PDF with Merge PDF, translation straight after the pages it covers, keeps them together and saves one of your limited attachment slots.

Check every file before you select Attach: open the PDF, scroll through all pages, and make sure nothing is cut off or upside down. Use a clear file name. Since you cannot remove a wrong file and there is a limit on the number of files, a quick check saves a lot of trouble.

Visa applications involve passports, finances and family details. Unlock PDF, Merge PDF, JPG to PDF and Compress Image run in your browser, so none of those files are uploaded anywhere except to ImmiAccount itself.
