How to Prepare Documents for Visa and Government Applications

Application portals are unforgiving. Two megabytes maximum, PDF only, one file per document, and no explanation when it fails. A rejected upload at 11pm the night before a deadline is a particular kind of misery.

Here is how to prepare a pack that goes through first time.

Read the requirements before you scan anything

Every portal publishes its rules and they vary more than you would expect. Write down four things before you start:

• File format. Usually PDF. Some accept JPG for photographs specifically.
• Maximum file size. Commonly 2 MB, sometimes 5 MB, occasionally 500 KB.
• One file or many. Some want each document separate; others want a single combined pack.
• Naming convention. Many portals specify one, and ignoring it causes rejections that look like technical errors.

Five minutes here saves an evening.

Step 1 — Capture the documents

A phone camera is fine if you are careful. What matters:

• Flat, even light — near a window on a cloudy day is ideal
• No shadow falling across the page, which means standing to the side rather than over it
• Camera parallel to the document, not angled
• All four corners visible, with a little margin
• Every word legible when you zoom in

Colour matters for anything with a stamp, seal or signature. Greyscale is fine for plain text and produces smaller files.

Step 2 — Make each document a PDF

Use Image to PDF. Add the photos for one document, put them in page order, choose A4 and a small margin, then create the PDF.

A4 matters here. Officials print these. A document sized to a phone photo’s proportions prints oddly and looks careless.

Do this once per document — one PDF for the passport, one for the bank statement, one for the degree certificate. Do not combine yet.

Step 3 — Get under the size limit

This is where most people get stuck. Three photos at 5 MB each make a 15 MB PDF, and the portal wants 2 MB.

Run it through Compress PDF and start with Balanced. A scanned document typically drops 70 to 85 per cent and stays perfectly readable. If you are still over, step up to Strong.

Then open the compressed file and read it properly at 100 per cent. Every number, every date, every name. If anything is ambiguous, go back to Balanced and reduce the size a different way — usually by compressing the photos first with Compress Image at 1600 px wide before building the PDF.

An illegible document is worse than a large one. Rejections cost weeks.

Step 4 — Combine or separate as instructed

If the portal wants one pack, use Merge PDF and put the documents in the order listed in the checklist. Officials work down that checklist; matching it makes their job easier and yours faster.

If it wants separate files, leave them separate. If you have combined something by mistake, Split PDF will pull it apart again.

Step 5 — Name the files properly

Follow the portal’s convention exactly if it gives one. If not, be boringly descriptive: Passport_AhmedKhan.pdf, BankStatement_Jan2026.pdf.

Avoid spaces, accented characters and symbols — older government systems still choke on them. Underscores are safe everywhere.

Before you press submit

• Open every file one last time and check it is the document you think it is
• Confirm every page is present and the right way up
• Check each file is under the size limit
• Confirm the format matches what was asked for
• Keep the originals and the finished files somewhere you can find them again

That last point matters more than it sounds. Applications get queried months later, and being able to resend the exact file you submitted saves an enormous amount of trouble.

Why this matters more than usual here

An application pack is the most sensitive collection of documents most people ever assemble — passport, national ID, bank statements, employment letters, educational certificates. Everything an identity thief would want, in one folder.

Uploading that to a free tool whose retention policy you have not read is a genuine risk, not a theoretical one.

Every tool on this site works inside your browser. Your documents are read from your device, processed in your device’s memory, and saved back to your downloads folder. Nothing is uploaded, so there is no server copy to leak and no deletion policy to trust.

It is also free for life, with no sign-up and no daily limit — which matters when you are compressing the same document six times to get under a stubborn 2 MB cap at midnight, and the last thing you need is a tool telling you to upgrade.
