How to convert JPG to PDF

To turn one or more JPG photos into a PDF, open Images to PDF, choose the pictures, put them in order and select Create PDF →. Each image becomes one page. The tool is free, needs no account, and builds the PDF in your browser, so the photos are not uploaded. It also accepts PNG and WebP files.

Before you start

File types: JPG, PNG and WebP. HEIC photos, the default on many iPhones, are rejected with the message “Use JPG, PNG or WebP images. HEIC is not supported.” See the fixes further down.
Limits: up to 30 MB per image, 100 MB in total and 25 images at once. A single picture larger than 50 megapixels has to be resized first.
Names: if the images are numbered in the right order before you start, such as “page-1.jpg” and “page-2.jpg”, sorting them later is quicker.

Step by step: convert JPG to PDF

The steps are the same in a browser on Windows, Mac, iPhone and Android. On a phone, tap instead of select.

Open Images to PDF.
Select Choose images, or drag the pictures onto the drop area. You can pick several at once.
To add more images, select Choose images again. New pictures go to the end of the list, and each one shows its file size.
Check the order. The top image becomes page 1. Use ↑ and ↓ next to a file name to move it.
Select × next to any picture you added by mistake.
Under Page size, choose A4, US Letter or Fit image.
Under Page orientation, leave Automatic unless every page must face the same way.
Select Create PDF →. When it finishes, you will see “Your file is ready.” and a line with the size, such as “16.02 MB. 4 images converted.”
Select Download result ↓. The file is named pdfreadygo-images.pdf. Save it before you leave the page.

To begin again with different pictures, select Start over.

Which page size should you pick?

US Letter (8.5 × 11 in) is the usual choice in the United States and Canada, and the safe pick for forms, applications and anything that may be printed there.
A4 (210 × 297 mm) is the standard paper size in most other countries.
Fit image makes each page the same shape as its picture, with no border. It suits screenshots, artwork and photos that will only be viewed on a screen. Pages can come out larger than any paper size, so do not choose it for a document that needs printing.

With A4 or US Letter, each picture is scaled to fit inside a small white margin and centered. Nothing is cropped or stretched, so a photo with a different shape from the page leaves extra white space at the top and bottom or at the sides.

Automatic orientation turns a page sideways when its picture is wider than it is tall. Choose Portrait or Landscape to make every page face the same way; a wide photo on a portrait page is simply shown smaller.

What we found when we tested it

We ran the steps on the live tool on October 31, 2026, in Chrome, with four sample JPGs made for the test: two phone-sized photos of a document (3024 × 4032 and 4032 × 3024 pixels, about 1 MB each), a smaller 1200 × 1600 picture (191.8 KB), and a photo stored sideways with the camera’s “rotate on display” tag.

With A4 and Automatic, the PDF had 4 pages in the order of the list: portrait, landscape, portrait, portrait.
The sideways-stored photo came out upright, following the camera’s tag. Firefox gave the same result.
Moving the first picture down one place with ↓ swapped the first two pages in the PDF.
With Fit image, each page matched its picture’s shape. Very large pictures are scaled so their longest side is 3,000 pixels.

The size surprised us more than anything else. The four JPGs added up to about 3.3 MB, but the PDF was 16.02 MB. A single 191.8 KB picture became a 1.27 MB PDF. The tool stores each picture in a lossless format inside the PDF, which keeps it sharp but makes the file several times bigger than the JPGs.

How to make the PDF smaller

If the PDF is too large to email or upload, run it through Compress PDF with Image-based — for scans and photos. In our test, the 16.02 MB file came down to 312.0 KB with Balanced · about 110 DPI and 675.2 KB with Higher quality · about 150 DPI. Optimize — keep page content did not help with this file: the tool reported “No size reduction was possible with this setting.” and gave back the original. If a portal sets an exact limit, choose Target size — for upload limits instead. How to reduce a PDF’s size for email explains the settings in more detail.

What if it does not work?

“Use JPG, PNG or WebP images. HEIC is not supported.” The picture is in Apple’s HEIC format. On an iPhone, Apple’s Camera setting Settings › Camera › Formats › Most Compatible makes new photos save as JPEG. Photos you already took can be exported as JPEG on a Mac from Photos or Preview with File › Export.
“Each file must be 30 MB or smaller.” Resize the photo or export a smaller copy, then add it again.
“An image is too large. Resize it below 50 megapixels first.” This applies to very high-resolution pictures such as panoramas. Save a smaller copy and try again.
A page is sideways. The picture itself is sideways, or its camera tag is missing. Turn that page in the finished PDF with Organize PDF, or see how to rotate a PDF and save it.
You cannot search or copy the text. Each page is a picture, and the tool does not include text recognition (OCR). That is also why PDF to Word finds no text in these files.

Quick answers

Are my photos uploaded? No. Images to PDF reads the pictures and builds the PDF in your browser, and the files are not sent to our servers. See how privacy works and the FAQ.

Can I add the photos to an existing PDF? Yes, in two steps. Convert the photos here, then combine both PDFs with Merge PDF. On a phone, follow how to combine PDFs on iPhone or Android.

Can I go the other way? Yes. PDF to JPG saves PDF pages as JPG or PNG images.
