Compress PDFs for Visa Applications (2026)
ImmiAccount has a 5 MB per-file limit. Here's how to reduce your PDF file sizes without losing quality using VisaPacks or free tools.
ImmiAccount — the Department of Home Affairs upload portal — has a strict 5 MB limit per file. Scanned documents from smartphones or flatbed scanners can easily exceed this, especially for multi-page documents or high-resolution identity scans. Here's how to reduce file sizes without making your documents unreadable.
Why files get too large
Most modern phones scan at 300 DPI by default, and some scanning apps save uncompressed or lightly compressed files. A 10-page document scanned at 300 DPI in colour can easily reach 15–20 MB. The solution is to resample the images inside the PDF to a lower resolution.
Using VisaPacks to compress
VisaPacks includes a built-in PDF compressor under PDF Tools. Upload your file, choose a quality level (Ebook is recommended for visa documents), and download the compressed version.
- Screen (72 DPI) — smallest file size, may be hard to read for fine print
- Ebook (150 DPI) — recommended for visa documents, clear and well under 5 MB for most scans
- Printer (300 DPI) — near-lossless, use only if lower settings reduce quality too much
After compressing, zoom into your document at 100% and check that text is still clearly legible and that signatures and stamps are readable. If they're not, use the Printer quality setting.
Preventing large files at scan time
The best compression is the one you don't need. When scanning:
- Set your scanner or app to 150 DPI — this is the sweet spot for visa documents
- Use PDF output rather than JPG (PDFs with embedded JPEG are smaller than raw TIFFs)
- Avoid scanning in 'Photo' mode — use 'Document' mode which compresses more aggressively
- On iPhone: the Files app scanner produces well-compressed PDFs by default
- On Android: Adobe Scan or Microsoft Lens both produce good compressed PDFs
What if compression still isn't enough?
If your compressed file is still over 5 MB, consider:
- Splitting the document into two separate PDFs and uploading to two checklist items
- Using Screen quality in the compressor for documents that don't contain fine print
- Re-scanning at a lower resolution (100–150 DPI)
