How do I convert a JPG to a PDF?
Add your JPG files, put them in the order you want with the arrows, choose Letter, A4 or the picture's own size, and press Make PDF. Each picture becomes one page, and the PDF is saved straight to your downloads. It is built in your browser, so the photos never leave your device.
Why turn JPG pictures into a PDF
A PDF is the format most offices, schools, landlords and agencies expect for a document, and a single PDF is easier to send and file than a folder of photos. Turning phone photos of receipts, forms, identity documents or a signed page into one PDF is the usual reason.
This tool puts one picture on each page. On Letter or A4 the picture is scaled to fit inside the margins and centred, with a landscape page for wide pictures. Choose 'same size as the picture' if you want the page to match the photo with no extra white space.
It runs in your browser. Your photos are never uploaded, and there is no account to make.
How it works
Your browser reads each picture with the File API, so nothing is uploaded. Each picture is redrawn on a canvas, which applies any rotation the photo carries and fills transparent areas with white, and is then saved as a JPEG at the quality you choose. Each JPEG becomes one page of the PDF. On Letter or A4 the picture is scaled down to fit inside the margin and centred, and a wide picture gets a landscape page; with 'same size as the picture' the page matches the picture. The tool then writes the PDF itself, following the structure in the PDF specification (ISO 32000-1): a catalogue, a page tree, one image object per page and a table of byte positions at the end. The file is saved to your downloads.
How to use it
- Add your JPG photos: drop them on the box, press the box to choose them, or paste.
- Use the arrows to put them in the order you want the pages in.
- Choose the page size (Letter, A4, or the same size as the picture), the margin and the picture quality.
- Press Make PDF and wait a moment: the page count and size are shown when it is done.
- Download the PDF and open it to check the order and the quality before you send it.
What changes and what stays the same
What the tool does to your file, and what it leaves alone.
| Aspect | What happens |
|---|---|
| Page size | Letter, A4, or 'same size as the picture'. On Letter or A4 the picture is scaled to fit inside the margin and centred; a wide picture gets a landscape page |
| Picture quality | Redrawn and saved as a JPEG at the quality you pick (Small file, Good or High); a picture is limited to 4,000 pixels on its longest side |
| Transparency | Filled with white, because a JPEG cannot be see-through |
| Photo rotation | Applied: a photo turned by a camera setting is placed the right way up |
| Camera details and location | Not carried into the PDF |
| Text in the picture | Stays a picture: the PDF has no selectable text. Use an OCR tool if you need text |
When to use it
- Sending several photos of a document as one file
- Submitting receipts or forms that must be a PDF
- Making a printable set of pictures
- Keeping a page-by-page record of a signed document
Problems you may run into
Most problems come from the file itself, not from the tool.
| What you see | Likely cause | What to do |
|---|---|---|
| The picture is rotated the wrong way | A phone photo stores its rotation in a tag that a program may ignore | This tool applies the photo's own rotation when it redraws the picture; if it is still wrong, turn the picture first with the rotate image tool |
| The PDF is very large | High picture quality and large photos make a big file | Choose Small or Good quality, or compress the finished PDF with the compress PDF tool |
| The text in my picture is blurry | Quality is set too low, or the picture was small to start with | Choose High quality and start with a larger picture; pictures are limited to 4,000 pixels on the longest side |
| A picture is missing | The format could not be read by your browser | Open it in a viewer, or convert it to JPG or PNG first |
| The pages come out in the wrong order | The list order is the page order | Use the arrows to move pictures up or down before pressing Make PDF |
Mistakes it helps you avoid
- Sending a PDF with the pages in the wrong order: reorder them before you make it.
- Using full-size phone photos and getting a very large PDF: choose 'Small file' or compress the pictures first.
- Forgetting a margin when the PDF will be printed.
- Photographing a page sideways: the photo's own rotation is respected, but check the preview thumbnails.
How the PDF is made
Each picture becomes a page, all in your browser.
1. Your browser reads each picture. Nothing is uploaded.2. Each picture is redrawn on a canvas (this applies a photo's rotation and fills transparent areas with white) and saved as a JPEG at the quality you choose.3. Each JPEG becomes one page. On Letter or A4 the picture is scaled to fit inside the margins and centred; wide pictures get a landscape page. With 'fit to picture' the page matches the picture.4. The pages are written into a PDF file in your browser and saved to your downloads.
The PDF is written directly in your browser following the file structure in the PDF specification (ISO 32000-1): a catalogue, a page tree, one image object per page, and a table of byte positions at the end. Pictures are limited to 4,000 pixels on the longest side to keep the file a sensible size, and are saved as JPEG inside the PDF, so a PNG's transparent areas become white. A page is 1/72 inch per unit, so Letter is 612 × 792 points.
Example: three photos of a form
You photographed the three pages of a form with your phone and an office wants one PDF.
- Addpage1.jpg, page2.jpg, page3.jpg
- OrderChecked with the arrows
- PageLetter, small margin
- Resultforms.pdf with 3 pages
One 3-page PDF, saved to your downloads
The PDF's size depends on the pictures and the quality you choose; the tool shows it when the file is made.

Common questions
Can I put several JPG files in one PDF?
Yes. Add as many as you like, put them in order with the arrows and each becomes one page.
Is my photo uploaded?
No. The PDF is made in your browser on your own device.
Which page size should I choose?
Letter is the usual paper size in Canada and A4 is common elsewhere. Choose 'same size as the picture' to avoid white borders.
Why is my PDF so large?
Phone photos have many pixels. Choose a smaller picture quality, or shrink the pictures first with the image compressor.
Does it keep the photo's rotation?
Yes. A photo taken sideways is shown the way it appears in a viewer, because the tool applies the camera's rotation before it is placed on the page.
