To convert JPG to PDF, add your images to the converter above, use the up and down buttons to put them in order, then pick a page size: Fit to image, A4 or US Letter, with or without a small margin. Click Convert to download one PDF with each image on its own page. JPG photos are embedded without re-compression.
How to use the JPG to PDF tool
- 1
Add your images
Drop one or more JPG, PNG, WebP, AVIF, GIF or BMP files onto the converter. Each image becomes one page of the PDF.
- 2
Arrange the order
Use the up and down buttons next to each image to set the page order. The first image in the list becomes page 1.
- 3
Choose page size and margin
Keep Fit to image (default) so each page matches its image exactly, or pick A4 or US Letter. Optionally add a small margin of about 0.5 inch (12 mm).
- 4
Create the PDF
Click Convert and download the finished PDF, ready to email, upload to a form or print.
Fit to image, A4 or US Letter: picking a page size
Fit to image, the default, makes every page exactly the size of its image. Nothing is scaled or padded, so it is the best option for sharing photos, screenshots or artwork in a PDF that will mainly be viewed on screen. Pages can end up with different sizes if your images do.
A4 and US Letter create standard paper-sized pages, which is what you want if the PDF will be printed or submitted to an office, school or government portal that expects a normal document. The image is scaled to fit and centred on the page, and the orientation is chosen automatically: wide images get landscape pages, tall images get portrait pages. A4 is the common standard in most of the world; US Letter is used mainly in the United States and Canada.
The small margin option leaves roughly half an inch of white space around each image. That helps when printing, since many printers cannot print right to the edge of the paper, and it gives scanned documents a cleaner, more familiar look.
Why your JPG photos don't lose quality
The PDF format can store JPEG data directly. This tool takes advantage of that: JPG files are placed into the PDF as they are, byte for byte, without being decoded and compressed again. The photo inside the PDF is the same photo you started with, and the PDF is not much bigger than the images combined.
PNG images are embedded losslessly as well. Other formats such as WebP, AVIF, GIF and BMP are first converted to PNG, which is also lossless, so their pixels are kept exactly. For animated GIFs, only a single still frame ends up on the page. The PDF is assembled with pdf-lib, an open-source JavaScript library, entirely inside your browser.
Photo to PDF: turning phone photos of receipts and documents into one file
A common use is collecting phone photos of receipts for an expense report, the pages of a signed form, or both sides of a document someone asked you to send as one PDF. Take the photos, add them here in the right order, choose A4 or US Letter so the result prints like a normal document, and download a single file.
These are often personal papers: ID cards, tax forms, medical bills, rental agreements. Because the PDF is built locally on your phone or computer, those images are never uploaded to Krawly or stored anywhere. When you close the tab, nothing remains except the PDF you saved.
iPhone photos are often saved as HEIC, which this tool does not read directly. Convert them first with HEIC to JPG, then add the JPGs here.
Tips for the best results
- Crop and straighten phone photos before converting; the tool places each image as it is.
- Pick A4 or US Letter for anything that will be printed or uploaded to an official form.
- Use the margin option if your printer cuts off the edges of full-page images.
- Check the order with the up and down buttons before converting; page 1 is the top of the list.
- To add images to an existing PDF, convert them here first, then join both files with Merge PDF.
Frequently asked questions
How do I combine multiple images into one PDF?
Add all the images to the converter at once, arrange them with the up and down buttons, choose a page size and click Convert. You get one PDF with each image on its own page, in the order you set. It is free, needs no account and runs in your browser.
Does converting JPG to PDF reduce image quality?
No. JPG files are embedded in the PDF exactly as they are, without being re-compressed, so there is no additional quality loss. PNG images are embedded losslessly, and other formats are converted to lossless PNG first. Choosing A4 or Letter only changes how large the image is displayed on the page.
Can I convert PNG, WebP or other images to PDF too?
Yes. Besides JPG, the tool accepts PNG, WebP, AVIF, GIF and BMP files, and you can mix formats in one PDF; the separate Image to PDF page uses the same engine. HEIC photos from iPhones need converting to JPG first with the HEIC to JPG tool.
What page size should I use for a scanned document?
Choose A4 if you are outside North America, or US Letter in the US and Canada. The image is scaled to fit and centred, and the page turns landscape or portrait automatically based on the image shape. Add the small margin if you plan to print it.
Are my photos uploaded when I make a PDF?
No. The PDF is built inside your browser with pdf-lib, so your photos never leave your device and are not stored by Krawly. That makes it suitable for receipts, IDs and other personal documents.
Can I put more than one image on a single page?
Not with this tool. Each image becomes its own page. If you need several pictures on one page, combine them into a single image in an editor first, then convert that image to PDF.
Private by design. Every Krawly converter runs inside your browser using JavaScript and WebAssembly. Your files are not uploaded, stored or seen by anyone — when you close the tab, they are gone.
