Organizing Travel Documents: Merging Passport Scans, E-Tickets, and Booking Confirmations into One A4 PDF

SENULA COMPANY · 2026-09-23 · 5 min read

Scattered Screenshots Are a Problem at the Gate

International trip planning leaves a trail of digital scraps: a passport ID page photographed on the kitchen table, airline e-tickets forwarded from a booking site, hotel vouchers screenshotted from a confirmation email, rail pass QR codes saved in a messaging thread. By departure day these files sit in five different apps, sorted by the timestamp they were captured rather than the order you need them.

At home with fast Wi-Fi, finding the right file takes a few seconds. At an immigration counter in a foreign airport with no data signal, it takes much longer—and the officer is not waiting. A single PDF with every document arranged in travel order can be opened offline, printed at any hotel business center, and handed over without scrolling through a camera roll of 400 photos.

What to Gather Before You Start

Pull together every file you might need before you begin merging. It is easier to remove an extra page than to realize you forgot your insurance certificate while standing in a taxi queue.

Name each file so that alphabetical sorting already puts them close to the right order—01-passport.jpg, 02-flight-out.png, 03-hotel.png, and so on. The tool sorts files by name when you first add them, so a naming convention saves reordering work.

Worked Example 1: Solo Trip to Osaka

Mina is flying Seoul → Osaka for five nights. She has seven screenshots and scans:

• 01-passport-scan.jpg (1.4 MB, 3024 × 4032 px)
• 02-flight-ICN-KIX.png (820 KB, 1170 × 2532 px)
• 03-flight-KIX-ICN.png (790 KB, 1170 × 2532 px)
• 04-hotel-namba.png (680 KB, 1170 × 2532 px)
• 05-jr-pass.png (540 KB, 1170 × 2532 px)
• 06-travel-insurance.jpg (1.1 MB, 2480 × 3508 px)
• 07-visa-waiver.png (310 KB, 1170 × 2532 px)

Total size: about 5.6 MB across seven files.

She adds all seven images to Images → PDF and confirms the alphabetical order matches her travel sequence. She selects A4 page size with medium margins so the tall phone screenshots sit centered with readable text. JPEG quality at 80 % and max long edge at 2000 px bring the output PDF to roughly 2.8 MB—seven pages, small enough to email to herself as a backup.

She prints one copy at the office, folds it into her passport holder, and saves the PDF to her phone's offline storage.

Worked Example 2: Family of Four to Portugal

Jun is traveling with his spouse and two children. He has collected 15 images:

• 4 passport scans (one per family member, each about 1.5 MB)
• 2 outbound flight confirmations
• 2 return flight confirmations
• 3 hotel vouchers (Lisbon 3 nights, Porto 2 nights, Faro 2 nights)
• 1 rental car confirmation
• 1 travel insurance certificate
• 2 Lisbon attraction pre-booking receipts

After adding all 15 files to Images → PDF, he notices a duplicate Lisbon hotel screenshot and removes it with the delete control, leaving 14 pages. He reorders them into trip sequence: passports → outbound flights → Lisbon hotel → Lisbon attractions → Porto hotel → Faro hotel → return flights → car rental → insurance.

With A4 format, small margins, JPEG quality at 85 %, and max long edge at 2400 px, the PDF is about 6.1 MB and 14 pages. At the hotel business center in Lisbon, he prints a fresh copy when the first gets crumpled in a backpack.

Open the finished PDF and zoom in on any page with a QR code or barcode. If the code looks soft or pixelated, re-scan that document at higher resolution and rebuild the file. A QR code that a scanner cannot read is worse than no QR code at all.

Balancing File Size and Print Clarity

Two settings control the tradeoff:

JPEG quality sets compression strength. At 90–100 %, images stay crisp but the file is large. At 70–80 %, file size drops by roughly half with little visible difference on printed text. For documents containing QR codes, stay at 80 % or above to keep the code scannable.

Max long edge scales oversized images down. A 4032 px phone photo reduced to 2000 px still prints clearly on A4 at about 240 DPI. Reducing to 1500 px makes a lighter file but may soften fine print or small confirmation numbers.

If the PDF is only for viewing on a phone, 1500 px and 70 % quality keeps a typical 7-page file under 2 MB. For printing at a hotel or airport, 2000 px and 85 % is a practical middle ground.

Privacy and Offline Access

Passport scans, booking references, and payment confirmations are sensitive personal data. Files added to Images → PDF stay in the browser. Nothing is sent to a server, stored remotely, or retained after the tab is closed. The tool also works offline once the page has loaded, so you can build or rebuild the PDF during a flight with no internet connection.

FAQ

Can I mix landscape and portrait screenshots in one PDF?

Yes. Each image is placed on its own A4 page. Landscape images and portrait images are both centered within the page margins. EXIF rotation data is applied automatically, so a photo taken sideways on a phone appears upright in the PDF.

What if I need to add one more document after I already created the PDF?

Add all images again—including the new one—reorder them, and generate a fresh PDF. Processing happens instantly in the browser, so rebuilding a 10-page file takes well under a minute.

Is there a page limit?

No fixed limit. The practical ceiling depends on your device's available memory. A modern phone or laptop handles 30–50 images without issues. For a solo trip with 7–10 documents, any recent device is more than sufficient.

One File, One Print, One Less Thing to Worry About

Build the PDF the evening before departure while you still have time to notice a missing voucher or an expired visa screenshot. Save it to your phone's offline storage, print one copy, and tuck it behind your passport. A single organized document is quicker to search than a camera roll—and it still works when the phone does not.
