Turning photos into a PDF is one of those small tasks that comes up constantly — a receipt to file, a stack of scanned pages, a set of ID photos, screenshots for a report. You want them as one tidy document, in the right order, that opens the same on any screen. The good news: every device you own can already do this, and a browser tool does it identically everywhere. Here’s how to convert JPG, PNG (and even iPhone HEIC) images to PDF on any device — how to combine several into one file, and how to get a clean result.
The quickest way: convert in your browser
You don’t need to install an app or pick the right one for your phone. Ream’s Images to PDF works the same on every device, right in the browser:
- Open Images to PDF and add your pictures — JPG, PNG, and more. Select several at once.
- Put them in order. Use the arrows to arrange the images; each one becomes its own page, top to bottom.
- Download your PDF — a single document with one image per page, at full quality.
Because it runs on your device, it behaves identically whether you’re on an iPhone, an Android tablet, a Mac or a Windows PC — and your photos never get uploaded anywhere.
Combining several photos into one PDF
The most common reason to do this is bundling — several receipts into one expense file, a multi-page contract you photographed, a batch of scans. Two things matter when you combine images: order and orientation. Add all the images, then use the reorder controls so page 1 is really page 1; mixing portrait and landscape shots is fine, each page simply fits its own image. If a photo comes in sideways, rotate the source first, or fix it afterwards with Rotate PDF. Added one by mistake? Delete Pages handles it.
On iPhone and iPad
iOS has this built in, and there are two easy routes:
- From Files: put your images in the Files app, tap Select, choose the pictures in order, tap the ••• menu, and pick Create PDF. A PDF appears right there.
- From Photos: select your photos, tap Share, choose Print, then pinch outward on the preview — that turns it into a PDF — and Share again to Save to Files.
Modern iPhones save photos as HEIC, not JPG. Both built-in methods handle it, and so does Images to PDF in Safari, so you don’t need to convert the format first.
On Android
Android’s universal trick is the print dialog. Open your image in Google Photos or the Files app, tap the menu and choose Print, then set the printer to Save as PDF and tap save. To combine several images, selecting multiple before printing works on many devices; if yours only prints one at a time, use Images to PDF in Chrome to merge them in one step.
On Mac
- In Finder: select your images, right-click, choose Quick Actions → Create PDF. A combined PDF appears instantly in the same folder.
- In Preview: open the images, drag them into the order you want and export, or choose File → Print → Save as PDF.
On Windows
Windows includes a virtual PDF printer. Select your image files, right-click and choose Print, then set the printer to Microsoft Print to PDF. In the print panel you can select multiple photos, then save one combined PDF. For finer control over page order, the browser tool is the simpler path.
| Device | Built-in route | Combine several? |
|---|---|---|
| Any (browser) | Images to PDF | Yes — with reordering |
| iPhone / iPad | Files → Create PDF | Yes |
| Android | Print → Save as PDF | Sometimes — varies by phone |
| Mac | Finder → Create PDF | Yes |
| Windows | Print → Microsoft Print to PDF | Yes |
A few tips for a clean result
- Keep the file size sensible. Photos are large, so a PDF of ten can be hefty. To email it, run the result through Compress PDF — our guide on shrinking a PDF for email covers how much you can save.
- Converting a scanned document? An image-based PDF isn’t searchable. Run it through OCR afterwards to add a real text layer — see making a scanned PDF searchable.
- Scanning with a camera? Scan to PDF captures pages directly and can enhance them for a cleaner document look.
- Watch orientation. Photos taken sideways sometimes carry rotation data that doesn’t survive — check the pages and fix any with Rotate PDF.
Is it private, and is it free?
Yes. Images to PDF builds the document in your browser, so your photos — often personal — never leave your device and nothing is stored on a server. It’s free, with no sign-up and no watermark stamped across your pages. If you’re weighing up any online tool, our note on whether online PDF tools are safe explains what to check.
Frequently asked questions
How do I combine multiple images into one PDF? Add them all to Images to PDF, arrange the order, and download — each image becomes one page of a single document.
Which image formats are supported? JPG/JPEG, PNG, WebP and iPhone HEIC. Each becomes its own page.
Can I convert an iPhone HEIC photo to PDF? Yes. The built-in Files and Photos methods handle HEIC, and so does Images to PDF in Safari — no need to convert to JPG first.
Can I reorder the images before converting? Yes — use the up and down arrows to set the sequence; the page order matches exactly.
Will the image quality drop? No — each picture is placed at full resolution. If the file is too big to email, compress it as a separate step rather than lowering quality up front.
My PDF of images isn’t searchable — why? Because it’s made of pictures, which have no text layer. Run it through OCR to make the text selectable.
Does it work offline / is it private? It runs in your browser, so once the page has loaded it keeps working, and your images are never uploaded.
Is it free? Yes — free, no account, and no watermark.
Whether you tap through your phone’s built-in tools or use a browser converter that works the same everywhere, turning images into a clean, ordered PDF is a two-minute job. Add your pictures, set the order, and download — and if the file needs slimming or the text needs to be searchable, compressing and OCR are one click away.
