A single document often lives across several files — a passport photographed page by page, a bank statement in three screenshots, a set of payslips. But ImmiAccount gives you one upload slot per document and accepts up to 60 files per applicant, so combining related images into one clean PDF is something almost every applicant has to do. This guide covers the free ways to merge photos and scans into a single PDF, and — the part people miss — how to keep that merged file under ImmiAccount's 5 MB limit.
Why one PDF per document matters
Uploading page 1, page 2 and page 3 of the same document as three separate images makes your application harder for a case officer to read and eats into your 60-file allowance. A single, correctly ordered PDF per document is what the Department expects — one file for the passport, one for the bank statements, one for the marriage certificate, and so on.
The free ways to merge images into a PDF
- On a Mac: open all the images in Preview, select them in the sidebar, and use File → Print → Save as PDF, or drag them into one PDF in the thumbnail sidebar
- On Windows: select the images, right-click → Print → Microsoft Print to PDF, which combines them in the order selected
- Online tools (iLovePDF, Adobe, and similar): drag your JPG/PNG files in, reorder the thumbnails, and export a single PDF — check the file-size limit and privacy of any site you upload sensitive documents to
- In VisaPacks: the merge tool combines PDFs, JPGs and PNGs into one file, then the compress and auto-naming tools finish the job in the same place
Uploading passport pages, bank statements and other identity documents to a random free website means handing your personal data to a third party. Prefer a tool that processes locally or that you already trust — in VisaPacks, free-tier files are processed and then kept in your own browser rather than uploaded to our servers.
Keeping the merged PDF under 5 MB
This is where most people get stuck: three phone photos merged into one PDF can easily exceed ImmiAccount's 5 MB per-file limit, because photos are far larger than scanned text. Merge first, then compress the finished PDF — don't try to shrink each image separately. Our guide to compressing a PDF for a visa application walks through getting any file under 5 MB without making it illegible.
In a VisaPacks checklist, merge and compress are built into every document item — combine your scans into one PDF, compress it if it's oversize, and export it with a correct file name, all without leaving the page. See our guide to compressing PDFs under 5 MB for the size side.
Common mistakes when merging
- Pages out of order — check the sequence before exporting; ImmiAccount shows the file exactly as you saved it
- A sideways or upside-down page — rotate images before merging, not after
- Forgetting to compress, so the merged file bounces back over 5 MB
- Merging unrelated documents into one file — keep one document per PDF (all passport pages together, but not passport + bank statement in the same file)
- HEIC photos from an iPhone that some tools can't read — convert to JPG first, or use a tool that accepts HEIC
Can I merge JPG and PDF files together into one PDF?
Yes. Most merge tools — including the one built into VisaPacks — accept a mix of PDFs, JPGs and PNGs and combine them into a single PDF in the order you arrange them.
Will merging photos into a PDF reduce their quality?
Merging on its own doesn't reduce quality — it just packages the images into one file. Quality only drops if you then compress the PDF too aggressively. Compress to the lightest setting that still leaves text and photos clearly legible.
What if the merged PDF is over ImmiAccount's 5 MB limit?
Compress the finished PDF rather than the individual images. Photo-heavy documents often need compression after merging. A standard compression setting usually brings a multi-photo PDF well under 5 MB while keeping it readable.
Do I need to install software to merge images into a PDF?
No. Mac Preview and Windows 'Print to PDF' are built in, and browser-based tools (including VisaPacks) do it with no install. For sensitive visa documents, prefer a tool that keeps your files private rather than uploading them to an unknown server.
