Twenty photos of receipts attached to an email is a mess: they arrive out of order, some upside down, and whoever receives them has to open each one. The same photos as a single PDF are one attachment, in the order you set, and print perfectly onto standard paper. Here's how to make that PDF from any device, plus how to pick the right page size.
Why a PDF Beats Sending Loose Photos
- Order is preserved: page 1 is page 1. Email clients and chat apps routinely shuffle or re-compress multiple image attachments; a PDF locks the sequence.
- One attachment: a single file is easier to forward, archive, and name ("March-receipts.pdf" instead of IMG_4021 through IMG_4040).
- Print-ready: photos are sized to a real paper format with margins, so they print without cropping or awkward scaling.
- Universally accepted: expense systems, university portals, and government forms that reject image files almost always accept a PDF.

Open the JPG to PDF Converter →Photos to PDF in 3 Steps
Step 1: Add Your Images
Open the JPG to PDF converter and select your photos - from the camera roll on a phone, or by dragging files in on a computer. JPG, PNG, and WebP can all be mixed in one document.
Step 2: Set Order, Page Size, Margins
Drag thumbnails to reorder them - each image becomes one page. Then pick a page size (A4, US Letter, or fit-to-image; see the comparison below) and a margin. A small margin looks cleaner for printed documents; zero margin suits full-page images.
Step 3: Convert and Download
Click convert and save the PDF. The conversion runs on your device, so 20 photos take a couple of seconds - and your pictures are never uploaded anywhere, which matters when they show ID documents, medical papers, or your home.
A4 vs US Letter vs Fit-to-Image: Which Page Size?
Page size only matters if someone might print the PDF. If it will only ever be viewed on screen, fit-to-image is the simplest choice.
| Page size | Dimensions | Best for |
|---|---|---|
| A4 | 210 × 297 mm | Printing everywhere outside North America; official forms in Europe, India, and most of the world |
| US Letter | 8.5 × 11 in | Printing in the US and Canada; US expense and HR systems |
| Fit-to-image | Matches each photo | Screen-only viewing; photos with unusual shapes (tall receipts, panoramas) that would waste space on a fixed page |
Tip: On A4 or Letter, portrait photos fill the page nicely while landscape photos are scaled down to fit the width. If most of your photos are landscape and printing doesn't matter, fit-to-image avoids the large empty bands above and below.
Where This Comes in Handy
- Expense reports: photograph a week's receipts, convert to one PDF in date order, attach it to the claim. Finance teams strongly prefer this to a zip of photos.
- Homework and assignments: handwritten pages photographed and submitted as a single A4 PDF - the format most university portals expect.
- ID document copies: passport photo page plus visa plus address proof as one file for landlords, banks, or applications.
- Scanned recipes and notes: turn a stack of photographed recipe cards or whiteboard shots into a browsable, printable booklet.

Frequently Asked Questions
Which image formats can I convert to PDF?▼
JPG, PNG, and WebP all work, and you can mix them in a single PDF. iPhone HEIC photos need converting to JPG first - share them via an app that converts automatically, or change the camera setting to Most Compatible.
Do I need to install an app on my phone?▼
No. The converter runs in the browser you already have - Safari on iPhone, Chrome on Android. Open the page, pick photos from your gallery, and download the PDF like any other file.
Will my photos lose quality in the PDF?▼
The images are embedded at their original resolution, so nothing is visibly degraded. If the resulting PDF is too large to email, compress the photos first with an image compressor and then convert - a 500 KB photo looks identical to a 5 MB one on screen and in print.
Can I control which photo appears on which page?▼
Yes. After adding images you can drag them into any order before converting. Each image becomes one page, in exactly the order shown.
Is there a limit on how many photos I can combine?▼
No fixed limit. Dozens of photos convert comfortably on any modern device; if you are combining hundreds of large photos on an older phone, do it in batches and merge the resulting PDFs afterwards.
