About this calculator
This tool turns a batch of JPG or PNG photos into a single PDF, with one image per page. It's handy for bundling scanned receipts, whiteboard photos, or a photo album into one file that opens the same way on any device.
How to use it
- 1.Choose the images you want in the document.
- 2.Put them in order with the arrows and pick a page size.
- 3.Select Create PDF and the finished document downloads.
Good to know
Matching each image keeps the picture at its natural size. A4 or Letter fits each image inside a standard sheet with the margin you set, which is better for printing.
Very large photos make large PDFs. Shrinking the images first, or running the result through the compress tool, keeps the file manageable.
How it works in plain English
Everything happens right in your browser using JavaScript and WebAssembly. When you choose your images, the page reads them locally, lets you drag them into the order you want, and builds the PDF on your own device. Nothing is uploaded to a server, nothing is stored anywhere, and the moment you close the tab the files are gone as if they never existed. There's no account to create and no email to hand over.
For each image, you decide how it sits on the page. The simplest option is to make the page the same size as the photo, so nothing is cropped or resized and the PDF pages come out in whatever dimensions the photos happen to be. Alternatively you can fit every image onto a standard A4 or US Letter sheet, which centres the picture and adds a small margin so it looks tidy next to text documents, and keeps every page in the finished PDF the same uniform size.
Once the order and sizing look right, the tool stitches everything together into one PDF and offers it as a direct download. Because the conversion runs locally, very large batches of images can take a few seconds longer on slower devices, but the process doesn't depend on an internet connection once the page has loaded, and there's no limit tied to a subscription or a daily quota.
Worked example
Imagine you photographed eight pages of a paper contract with your phone and need to send them as one document instead of eight separate photos. You open the tool, select all eight JPGs at once, and drag two of them into the right order because they were shot slightly out of sequence.
You choose the 'fit to A4 with margin' option so every page matches the size people expect from a printed document, then generate the file. The result is a single eight-page PDF, ready to attach to an email, with each photo landing on its own page in the order you set.
Typical page sizes used when fitting images to a standard sheet
| Page size | Width x height (points) | Common use |
|---|---|---|
| A4 | 595 x 842 | Most countries outside North America |
| US Letter | 612 x 792 | United States, Canada |
| Match image | Varies per photo | Keeps original resolution, no cropping |
| A4 with margin | 595 x 842, inset image | Neater look for mixed documents |
| US Letter with margin | 612 x 792, inset image | Neater look for mixed documents |

Frequently asked questions
Are my photos uploaded anywhere when I convert them?
No. The whole conversion happens inside your browser using JavaScript and WebAssembly. Your images are read from your device, assembled into a PDF on the spot, and never sent to a server. Once you close the page, everything is cleared automatically, and there's no account or history that keeps a copy anywhere.
Can I mix JPG and PNG files in the same PDF?
Yes. You can select JPGs and PNGs together in one batch, and the tool places each one on its own page regardless of format. There's no need to convert PNGs to JPG first, and transparency in a PNG will simply show against a plain background on the page.
What happens if my photos are different sizes?
If you choose 'match image', each page in the PDF takes on that photo's own dimensions, so pages can vary in size throughout the document. If that looks inconsistent, switching to the A4 or Letter fit option makes every page the same size, scaling and centring each image with a margin.
Is there a limit to how many images I can combine?
There's no fixed limit built into the tool itself, since everything runs on your own device rather than a server with usage quotas. In practice the number of images you can comfortably combine depends on your device's memory and processing power, with very large batches simply taking a bit longer to process.
Can I reorder images after selecting them?
Yes. Once your images appear in the tool, you can drag them into whatever order you want before generating the PDF. This is useful when your file picker doesn't list photos in the sequence you need, letting you fix the order without renaming or re-selecting any files.
