Preparing Visa Application Documents as PDFs: A Checklist

To prepare visa documents for an online portal, read the portal's file rules first (accepted formats, maximum size per file, and whether each document needs its own upload), then scan each document clearly, convert photos to PDF, combine pages that belong together into one file, keep each file under the size limit, and name files descriptively. Most portals want PDFs for documents and JPG for the applicant photo. Check everything once more before submitting, because changes after submission are often difficult.

This guide covers file preparation only. Requirements for which documents you need differ by country, visa type and your circumstances, and they change. Always follow the official government or embassy website for your application, not third-party summaries, including this one.

Step 1: Read the upload rules

Before scanning anything, find the portal's technical requirements. They usually state:

• Accepted formats: often PDF for documents; JPG or JPEG for photos.
• Maximum file size: commonly a few megabytes per file; some portals allow less than 1 MB.
• One file per document type or several: for example, "upload all bank statements as one PDF".
• Photo specifications: pixel dimensions, file size, background colour and head size.
• Language: whether translations are required and who may certify them.

Write these down. They decide every later step.

Step 2: Scan clearly

Officials need to read every word, stamp and signature.

• Use a flatbed scanner if you have one, at 200–300 DPI; colour for documents with coloured stamps or photos, greyscale for plain text.
• A phone works too. Use a document-scanning mode, which crops and flattens automatically. Our guide to scanning documents with your phone explains lighting and angles.
• Capture the whole page, including edges, stamps and page numbers. Do not crop off the corners.
• Scan every page, including blank-looking back sides if they carry stamps.
• Passport: scan the photo page and any pages with visas or entry stamps if requested.

Step 3: Turn photos into PDFs

If you photographed documents, convert them with Image to PDF. Choose A4 or Letter as the page size so documents print at a normal size if an officer prints them. Add the pages in the right order; the file order becomes the page order.

Step 4: Combine documents that belong together

A six-month bank statement saved as six separate files is harder to review than one PDF. Use Merge PDF to combine:

• all pages of one statement or one certificate;
• several months of payslips, if the portal asks for one upload;
• a document and its certified translation, translation directly after the original, if the instructions allow this.

Do the opposite when needed: if a portal wants only certain pages, extract them with Split PDF.

Step 5: Get under the size limit

Phone-photo PDFs are often too big. Fix it before you reach the portal:

1. Compress the photos with the Image Compressor before making the PDF, or
2. Rescan at 150–200 DPI in greyscale for text-only pages.
3. For PDFs produced by software, try the lossless Compress PDF tool, and see our guide to getting a PDF under an upload limit.

After compressing, open the file and zoom in on the smallest text and the stamps. If they are not readable, compress less.

Step 6: Prepare the photo separately

The applicant photo is usually uploaded as a JPG with strict rules: exact pixel dimensions, a maximum file size, a plain light background, and a specific head size. The Passport Photo Maker helps with physical prints; for digital uploads, resize with the Image Resizer and compress to the KB limit. Our list of passport photo sizes by country gives common sizes, but the official specification for your application always wins.

Step 7: Name files clearly

Portals sometimes keep your file names, and officers see them. Good names help:

• Surname_Passport_Bio-page.pdf
• Surname_Bank-statements_2026-04_to_2026-09.pdf
• Surname_Employment-letter.pdf
• Surname_Birth-certificate_with-translation.pdf

Avoid names like scan0001.pdf or IMG_4521.pdf.

Step 8: Do not protect files with passwords

Visa portals and officers need to open your files. Do not password-protect PDFs you upload to an official portal unless the instructions ask you to. A locked file may be rejected or delay the decision. If a document arrived password-protected (some e-statements do), remove the password with the PDF password tool using the password you were given, before uploading.

Common mistakes that cause delays

Most file problems on visa portals come from a handful of avoidable mistakes:

• Photographing a screen instead of the original document or the official PDF download. Moiré patterns and glare make text hard to read.
• Cropped edges that cut off stamps, signatures, page numbers or the issuing office's details.
• Mixed-up family files. In a family application, upload each person's documents under that person's profile, and put the applicant's name in every file name.
• Out-of-date documents, such as bank statements that end too long before the application date. Check the date window the instructions give.
• Over-compressed scans where stamps and small print turn into blur. A slightly larger file that is readable is always better.

Final check before submitting

1. Each file opens on a computer and a phone.
2. Every page is readable, including stamps and small print.
3. Pages are in the right order and the right way up (fix with Rotate PDF).
4. Every file is under the size limit and in the accepted format.
5. Names and dates match across documents and your application form.
6. Translations are included where required.
7. Nothing is password-protected.

Keep a copy of the whole set in one folder, along with your submission confirmation.
