How to Turn Phone Photos Into One PDF (iPhone and Android)

Lots of forms ask for "a PDF", but what you have is a few photos in your gallery: both sides of an ID, three pages of a letter, a receipt. The fix is to put the photos into one PDF, in the right order, with sensible page settings. You can do it in your phone's browser in a minute.

This guide covers the quickest way, the iPhone photo-format issue, and how to make the result look like a proper document rather than a stack of snapshots.

Photos you already have vs. photos you're about to take

• Already in your gallery? Use JPG to PDF. It takes JPG, PNG and WEBP images and turns them into a single PDF.
• Still on paper? Use Scan to PDF instead. It opens the camera, lets you crop each page by its four corners with perspective correction, and has document filters (black and white, grayscale, more contrast). The result looks like a scan, not a photo of a table.

Both run in your browser. The photos aren't uploaded anywhere. The PDF is built on your phone and downloaded.

The iPhone HEIC question

By default, many iPhones save photos in HEIF/HEIC ("High Efficiency") instead of JPEG. Apple's support page explains the choice under Settings > Camera > Formats:

• High Efficiency saves photos as HEIF, which uses less storage.
• Most Compatible makes all new photos use JPEG.

Not every browser can open HEIC files. In JPG to PDF, HEIC works only if your browser can open it, for example Safari on iPhone. If your HEIC photos won't load, you have two options:

1. Use Safari, which normally opens them.
2. Switch to Most Compatible before taking the photos, so they're saved as JPEG. This only affects new photos, not ones you already took.

Step by step

1. Open JPG to PDF and select your photos. On a phone, the picker lets you choose several from your gallery at once.
2. Put them in order by dragging the thumbnails. For an ID, front then back. For a letter, page 1, 2, 3.
3. Choose a page size:
   • A4 or Letter if the PDF should look like a normal document (Letter is standard in the US and Canada, A4 in most other countries).
   • Same as image if each page should be exactly the photo, with no white border.
4. Orientation: automatic works for most sets. It chooses portrait or landscape for each page based on the photo. You can force portrait or landscape if you prefer.
5. Margin: none, small or large. A small margin looks tidy when printed. Choose none if you want the image to fill the page.
6. Create the PDF and download it.

The tool respects the orientation your camera recorded, so photos you took sideways shouldn't come out sideways. JPG photos that don't need rotating are placed in the PDF as they are, without recompression.

Fixing order or rotation afterwards

If you notice a page in the wrong place or upside down after creating the PDF, you don't have to start over. Organize PDF lets you drag pages into a new order, rotate or delete individual pages, and even insert a blank page.

Keeping the size down

Phone photos are large, often several MB each, and a PDF made from them is roughly as big as the photos combined. If the portal or email has a limit, run the PDF through Compress PDF. It recompresses the photos inside, shows the size before and after, and can target a specific size ("Compress to X KB"). Zoom in on the result to make sure small text is still readable.

Photos or a real scan?

JPG to PDF places each photo on a page as it is. It doesn't crop to the edges of the paper or straighten a tilted page. That's fine for screenshots, pictures of products, or photos you took carefully. For paper documents where you want clean edges and high-contrast text, use Scan to PDF instead: it lets you drag the corners onto the page, corrects the perspective and applies a document filter. You can pick existing photos in Scan to PDF too, if you don't give it camera access, so you can still clean up pictures you already took.

Tips for photos that make good pages

• Shoot straight down, with the document filling most of the frame.
• Even light, no flash on glossy cards or laminated documents.
• Plain, darker background so the edges are clear.
• One document per photo. Two receipts in one picture make a confusing page.
• Check sharpness by zooming into small print before you leave. It's easier to retake the photo now than later.

Common mistakes

• Wrong order, especially front and back of IDs. Check the thumbnails before creating.
• Mixing screenshots and photos at different sizes. Use A4 or Letter pages so they look consistent.
• Using "Same as image" for printing. Pages can end up with odd sizes. Choose A4 or Letter if someone will print them.
• Uploading the photos instead of the PDF. Some portals take only one file per field, so one combined PDF is what they want.

Checklist

• Photos in JPG, PNG or WEBP (or HEIC in a browser that opens it).
• Pages in the right order and upright.
• Page size chosen for how the PDF will be used.
• File size checked against the limit.
