Australian visa applications ask for a lot of evidence, and each attachment has to fit under a per-file limit before you can pay and submit. You attach documents one at a time, with a type and a description, so a refused file is easy to notice and easy to fix. This page is about making each file fit.
Why ImmiAccount has this limit
The Department's help page states the rule without giving a reason: the maximum file size for each attachment is 5 MB, and the number of files that can be attached ranges from 30 to 60 depending on the application type. The page spells the unit Mb; FitSize reads it as megabytes and uses the smaller decimal reading.

What FitSize does with your file
FitSize aims for a size safely under the per-attachment limit and treats every document separately, because ImmiAccount does. Since the number of attachments is also capped, combining related pages into one PDF before compressing keeps you under the file count as well as the file size.
Your file never leaves your device. It is read and compressed by your browser, and nothing is uploaded to a server.
Three things to watch on ImmiAccount
- Size and count are separate limits. Each attachment can be up to 5 MB, and the number of files ranges from 30 to 60 depending on the application type, so a long list of small files can hit the count before the size. Source: immi.homeaffairs.gov.au
- You attach before you pay. The Providing supporting evidence page appears after the Review page, and you are prompted to attach documents before paying and submitting. Additional documents can be attached after lodging, using a separate quick reference guide. Source: immi.homeaffairs.gov.au
- The unit is spelled Mb. The page says 5Mb, which literally means megabits. FitSize reads it as megabytes and aims below that number, so a file that fits under either reading is accepted. Our reasoning, from immi.homeaffairs.gov.au
