How to Convert JPG and PNG to PDF: Several Photos in One File

How to convert JPG and PNG into a single PDF

To combine images into a PDF, upload your JPG or PNG files in the Convert image to PDF tool, adjust the order if needed and click "Convert and download". You get a single PDF with one image per page, in the order of the list. Everything happens in your browser, with no sign-up and without sending your photos to any server.

Instead of sending five or ten loose photos, you deliver one document that the other person opens with a click and reads in the order you planned. It works for phone photos, screenshots and images exported from other programs.

Step by step to combine images into a PDF

1. Open the "Convert image to PDF" tool.
2. Upload your JPG or PNG images; with several files, the list shows them in upload order.
3. Adjust the order, if needed, with the ↑ and ↓ arrows that appear next to each file when there is more than one; "Remove" takes an image off the list.
4. Click "Convert and download" (with several images the button reads "Convert N images"). The PDF downloads right away: with one image it keeps that image's name; with several, it is called atlasdocs-imagens.pdf.

Each image gets its own page, so nothing is cropped or squeezed next to another photo. Pages take the size of the smallest image you uploaded; larger ones are scaled down to fit, centered and uncropped. To keep your photos' resolution, upload images of similar size, for example all taken with the same camera.

What the tool does not do: there is no option for margins, orientation or paper size (A4, letter). The page takes the size of the image; when the images have different proportions, a white strip is left at the sides or above and below the scaled-down photo. There is no extra compression either: each photo goes into the PDF as is, with no quality loss, so the PDF ends up roughly the size of all the photos added together. If you need a smaller file, shrink the photos before uploading. For that, see how to reduce image file size.

The image order becomes the page order

Since each image becomes a page, the order of the list is the order of the PDF: the front and back of a document, the pages of a contract in the right sequence, the photos of a portfolio in the order that tells the story best. If you uploaded them out of order, there is no need to start over: use the arrows next to each file to move an image up or down before converting.

Which formats are accepted (and what to do with HEIC and WebP)

• Accepted for conversion: JPG (or JPEG) and PNG.
• Refused at conversion: WebP and GIF. They do enter the list, but when you click, you see "Unsupported image format (use JPG or PNG)." No PDF is generated.
• HEIC (the default format of iPhone photos) does show up in the list of uploaded files, but this converter does not count it: it is left out of the PDF with no warning at all.
• Output: a single PDF file, one page per image, at the same resolution as the original photos when they share the same size.

If the photo came as HEIC, convert it to JPG first with the HEIC to JPG tool. If it is WebP or GIF, run it through the Change image format tool and save it as JPG or PNG. Both also run in your browser, and then you just come back here and build the PDF. The guides are how to convert iPhone HEIC photos to JPG and how to convert image formats.

When an image PDF comes in handy

• Sending photographed documents: ID cards, proof of address or payment, receipts or signed contracts you captured with your phone.
• Building a portfolio: gathering photos of work, projects or products into one presentation file.
• Merging screenshots: turning a sequence of captures into an easy-to-read walkthrough.
• Archiving: keeping several related images as a single organized document.

Common mistakes when combining images into a PDF

The most frequent one is mixing a huge photo with a small screenshot: the page takes the screenshot's size and the large photo is scaled down to fit. If resolution matters, resize the screenshot first or build two PDFs. Another one is uploading an iPhone photo without converting it: HEIC stays in the list but does not go into the PDF, and no warning appears. Finally, check the order before you click, because this tool has no page editor for the finished PDF.

Everything happens in your browser: your images are never sent to any server. Close the tab and nothing is kept.

Real limit: only JPG and PNG go into the PDF. A WebP or GIF image stops the conversion with a warning, and a HEIC one is skipped without warning, so change the format first.
