Image to PDF means turning one or more picture files, such as JPG or PNG photos and scans, into a single PDF document. The converter below does this entirely inside your browser: you pick your images, choose a page size, and it writes a PDF on your device that you can download. Nothing is uploaded to a server.
What Converting Images to PDF Does
Converting an image to PDF wraps the picture in a PDF page so it opens the same way on any device and prints at a fixed size. A PDF holds the image in a layout that does not depend on the viewer’s photo app, which is why PDF is the format people ask for when they want a scan, a receipt, or a set of photos kept together as one document. Each image you add becomes one page in the file, and the pages keep the order you selected them in.
How to Use It
- Press the file selector and choose one or more JPG or PNG images. Select them in the order you want them to appear.
- Pick a page size: Fit to image keeps each picture at its own dimensions, while A4 or Letter places each image on a standard page with a margin.
- Press Create PDF. The file is built on your device.
- Click the download link to save images.pdf, then open or print it like any other PDF.
Fit to Image vs A4 or Letter
JPG vs PNG in PDFs
| Aspect | JPG | PNG |
|---|---|---|
| Best for | Photos and scans | Screenshots, logos, line art |
| Compression | Lossy, smaller files | Lossless, larger files |
| Transparency | No | Yes (flattened in the PDF) |
| Effect on PDF size | Usually smaller | Usually larger |
Both formats work in the converter. JPG images keep their compression and tend to produce a smaller PDF, which suits photographs. PNG images stay lossless, which keeps text and sharp edges crisp in screenshots and diagrams, at the cost of a larger file.
Multiple Images Make a Multi-Page PDF
When you select more than one image, each one is added as its own page in a single PDF, in the order you chose them. This is how you turn a folder of scanned pages or a batch of photos into one document you can send or archive. The page count and the file size are shown after the PDF is built so you can confirm every image was included before you download.
Everything Stays in Your Browser
The conversion runs with code that loads in your browser, and your images are read from your own device. No image is sent to a server, logged, or stored anywhere. You can confirm this by disconnecting from the internet after the page loads and watching the converter still build the PDF. This makes it safe to convert private scans, identity documents, or receipts on any network.
When to Use It
Use an image to PDF converter when you need to submit photos as a document, combine scanned pages into one file, send a receipt or form that was captured as a photo, or archive a set of screenshots in a fixed order. PDF is the format most forms, portals, and email recipients expect, so converting first avoids the back and forth of someone asking for a single document instead of loose image files.
Last Thoughts on Converting Images to PDF

Key Takeaways:
- Image to PDF turns JPG or PNG files into a single PDF document, one page per image.
- Fit to image keeps each picture at its own size; A4 and Letter place images on standard printable pages with a margin.
- JPG suits photos and gives smaller files; PNG suits screenshots and line art and stays lossless.
- Selecting several images builds a multi-page PDF in the order you chose them.
- The conversion runs in your browser, so no image is uploaded; the page count and file size confirm the result before download.
Frequently Asked Questions (FAQs)
Are my images uploaded when I convert them?
No. The converter reads your images directly from your device and builds the PDF in your browser. Nothing is sent to a server, logged, or stored. You can disconnect from the internet after the page loads and the tool still works, which confirms the files never leave your computer.
Can I combine several images into one PDF?
Yes. Select multiple JPG or PNG files and each one becomes a separate page in a single PDF, in the order you chose them. This is the standard way to turn a batch of scanned pages or photos into one document.
What is the difference between Fit to image and A4 or Letter?
Fit to image makes each PDF page the exact size of the picture, so there are no borders. A4 and Letter place each image, scaled to fit, on a standard printable page with a margin. Choose Fit to image for photos and screenshots, and A4 or Letter when the PDF will be printed or sent as a formal document.
Which formats can I convert?
The tool accepts JPG and PNG images. JPG keeps its compression and usually makes a smaller PDF, which suits photos. PNG stays lossless, which keeps screenshots and line art sharp at the cost of a larger file.
How do I control the order of the pages?
The pages follow the order in which you select the images in the file picker. Choose your images in the sequence you want them to appear, and the PDF keeps that order from first page to last.
Is there a limit on the number of images?
There is no fixed limit, but very large batches or very high-resolution images use more memory in your browser and take longer to process. For most jobs, such as a set of scans or a handful of photos, the PDF builds in a few seconds.
