How to convert JPG to PDF

The short answer

To convert JPG to PDF, add your images to a converter, put them in the order you want, pick a page size and download the PDF. With Toolbyte's JPG to PDF tool this takes a few clicks, works with one image or many, and runs in your browser so the pictures are not uploaded.

Convert one JPG to PDF

A single image becomes a one-page PDF. The steps are:

1. Open JPG to PDF.
2. Add the image. On a phone, choose it from the gallery, or take a new picture if your browser offers the camera.
3. Choose the page size, orientation and margin (explained below).
4. Click Convert to PDF.
5. Download the file and open it to check it.

Convert several images into one PDF

Several images become one PDF with one image on each page, in the order shown in the list. This is the common case for scanned documents, receipts, certificates or photos of a handwritten page. After you add the files:

• Drag them into the order you want before converting. Page one is the top of the list.
• Remove any image you added by mistake.
• Check that every picture is the right way up. Phone photos that carry a rotation tag keep the correct orientation.

If your files have names like IMG_2041 and IMG_2042, the list might not match the order you shot them. Look at the thumbnails, not the names.

Choose the right page size

The page size decides how your image sits on the page, so pick it based on what you will do with the PDF. Toolbyte offers three choices:

• A4: the standard paper size in most of the world. Good for documents you will print or email.
• US Letter: the standard size in the United States and Canada.
• Fit to image: each page is exactly as large as its picture, with nothing added around it. Good for screenshots, long receipts and scans where you do not want white borders.

For A4 and Letter you can also pick portrait, landscape or automatic orientation. Automatic turns a wide photo sideways so it fills the page better. You can add a margin of none, small or large. Use a small margin for documents that you will print, because many printers cannot print right to the edge.

Keep the file size under control

The PDF will be about as big as your images together, because the images are embedded as they are. Phone photos are often 2 to 6 MB each, so ten of them can make a 30 MB PDF. That can be too large for an email attachment or an upload form. If you have a size limit, shrink the images before you convert:

1. Run each picture through compress image, or one of the fixed-size pages such as 200 KB.
2. Then convert them with JPG to PDF.

Doing it in this order works better than trying to shrink the finished PDF, because the images are what make it large. For more on this, read our guide to reducing PDF size.

When the pictures are not JPG

You do not have to convert the images first. PNG images work directly, including transparent ones, and WebP images are converted to JPG before they are added to the PDF. If you only have HEIC photos from an iPhone, change the camera format to "Most Compatible" in Settings or export them as JPG before adding them.

Tips for scanned documents

A few habits make a phone-scanned PDF look professional:

• Photograph the page flat, from directly above, in even light. Avoid shadows from your hand or phone.
• Crop each image to the edges of the page with crop image so there is no table or floor around it.
• Use Fit to image if you do not want white borders, and A4 if the receiving office expects standard pages.
• Keep a consistent order: first page first. Check the final PDF before you send it.
• Name the result clearly, such as rent-agreement-2026.pdf, so the recipient knows what it is.

After you have the PDF

If you later need to add more documents, merge the new PDF with others using Merge PDF. If you need to turn it back into pictures, PDF to JPG exports every page as an image in a ZIP. To add page numbers, use Add page numbers to PDF.

Is it private?

Yes, your images are turned into a PDF inside your browser and are not uploaded, so IDs, certificates and bills stay on your device. This is useful when you are making a PDF of documents you would not want on a stranger's server.
