JPG to PDF Converter
Turn JPG photos and other images into one PDF in your browser, in the order you choose, on A4, Letter or pages that fit each picture.
How to convert JPG to PDF
Everything happens in your browser: the images are read, put in order and written into the PDF on your own device.
- Choose or drop up to 20 images. JPG, PNG, WebP, HEIC and AVIF can be mixed.
- Put the pages in order: drag a picture by its thumbnail, or tap the arrows next to it on a phone.
- Pick the page size, orientation and margin, or keep A4 with automatic orientation and a small margin.
- Press Create PDF, check the number of pages and the size, then download the PDF.
Why my photos go into the PDF unchanged
I am a photographer, and every JPG I publish has already been through one careful export. Most JPG to PDF converters I tried decode the photo and compress it again before they put it on the page. That second round costs detail and often makes the file bigger rather than smaller, with nothing gained.
A PDF can hold a JPEG file exactly as it is, so I built this tool to do just that. A JPG keeps its own bytes and only gets a page around it. To check, I put three of my photos into one PDF: Lake Jasna in portrait and two frames from Metelkova in Ljubljana. Together the three files are 1,556,778 bytes. The PDF came out at 1,558,417 bytes, only 1,639 bytes more, and each photo inside it is identical to the file I chose, byte for byte.
Three of my photos as one PDF
| Page setup | Pages | |
|---|---|---|
| A4, automatic orientation, small margin | 595.28 × 841.89 pt, the two Metelkova pages turned to landscape | 1,558,417 bytes |
| Letter, automatic orientation, small margin | 612 × 792 pt, the two Metelkova pages turned to landscape | 1,558,373 bytes |
| Fit to image, no margin | 673.51 × 841.89 pt for the lake, 841.89 × 561.26 pt for the others | 1,558,403 bytes |
The page setup barely moves the size, because the photos themselves make up more than 99.8% of the file. Choose the page size you need for printing or sending, not to save space.
A4, Letter or fit to image
A4 is the paper size in Europe and most of the world, Letter in the United States and Canada. Use the one your printer or the office that asked for the document uses. Each image is scaled to fill the page inside the margin and centred, so nothing is cropped.
Fit to image gives each page the shape of its picture. The longer side of every page is as long as the long side of A4, so a landscape photo becomes a wide page and a portrait photo a tall one, with no white bands. I use it when a PDF is going to be looked at on a screen rather than printed.
Orientation and margins
With Auto, each page is turned to suit its own image: in my test the portrait lake stayed on an upright page and the two wide Metelkova photos got landscape pages. Choose Portrait when every page should be upright, as for a form or a stack of receipts. A wide image is then smaller on the page.
The small margin is 18 points, a quarter of an inch, and normal is half an inch. Most office printers cannot print to the very edge of the paper, so keep at least the small margin for anything you will print.
What happens to each format
PNG, WebP, HEIC and AVIF cannot go into a PDF as they are, so the tool saves each of them once as a JPEG at 85% quality. Transparent areas become white, like the paper. A 2200 × 1400 px screenshot that was a 466.7 KB PNG became a one-page PDF of 155.6 KB, with the text still sharp.
If a phone photo was saved sideways with a note that tells viewers to turn it, the page is turned to match, without touching the JPEG.
Because a JPG is not changed, its camera details travel with it into the PDF: my red bicycle photo still names the Sony A7 III it was taken with. If your photos record where they were taken and the PDF is going to strangers, run them through the Image Converter first, which writes new files without those details.
How sharp will it print?
Nothing is scaled down, so the PDF has every pixel you put in. Whether that is enough for print depends on the photo. My 1200 px wide Metelkova photos cover a landscape A4 page at about 107 pixels per inch, fine for a document and soft for a framed print. A print at 300 pixels per inch across the same page needs a photo about 3,400 px wide.
Tips for better results
- Name the first image well: the PDF takes its file name from it.
- Put the pages in order before you press Create PDF; changing the order or the page setup asks for a new PDF.
- For a document someone will print, keep A4 or Letter with at least the small margin.
- If the PDF has to stay under an upload limit, make the photos smaller with the Image Compressor first.
- Twenty large phone photos take a moment to open on an older phone; each one is opened on its own, one after another.
Privacy
What you add here never leaves your device. The PDF is put together entirely in your browser, so nothing is uploaded or stored, and you do not need an account. HEIC photos are opened with a decoder that comes with this site and also runs in your browser.
Frequently asked questions
Can I convert JPG to PDF without losing quality?
Yes. A JPG goes into the PDF exactly as it is, without being compressed again, so it has the same pixels and the same detail. My three photos came out byte for byte identical inside the PDF.
Can I merge several JPG files into one PDF?
Yes. Choose up to 20 images at once or add more with Add more images. Each one becomes a page, in the order of the list, and you get a single PDF file.
How do I make a PDF without margins?
Set Margin to None. With Fit to image as well, every page has exactly the shape of its picture and there is no white border at all, which suits a PDF that will be viewed on a screen.
How do I convert JPG to PDF on an iPhone?
Open this page in Safari, tap the box and choose the photos from your library. Put them in order with the arrows, tap Create PDF and then Download PDF. The file is saved in the Files app.
Can I make the PDF smaller, for example under 200 KB?
The PDF is about as large as the images in it, so make the images smaller first. The Image Compressor can bring each photo to a target size, and those files then go into the PDF unchanged.
Does the PDF get a watermark?
No. The PDF holds only your images, one per page, with no watermark, logo or added text. There is no account and no limit on how many PDFs you make.
