Convert JPG and PNG Images to PDF

What is a JPG to PDF converter?

A JPG to PDF converter takes one or more image files — JPGs, PNGs, screenshots, scanned receipts — and combines them into a single PDF, one image per page, in whatever order you choose. This one runs entirely inside your browser tab: the images never leave your device, because there is no server involved in the conversion at all.

That matters for what people actually use it for. You are not exporting a design file; you are turning a phone camera roll into something you can attach to an email, print, or archive. A JPG to PDF conversion is really just packaging — take an image, wrap it in the PDF page format, keep the pixels intact. Do that well and the tool gets out of your way.

How to use it

1. Add your images. Drag a batch of JPGs or PNGs into the drop zone, or click it to choose files — drop several at once and each one becomes its own page.
2. Put them in order. The list shows a thumbnail, filename and pixel size for each image; use the up and down buttons to set the page order, the remove button to drop one, and Add more images if you left one out.
3. Choose a page size and download. Pick Fit to image, A4 or Letter, set the orientation and margin if you chose A4 or Letter, then hit Download once the page count and output size look right.

What happens to image quality

JPEG and PNG files go into the PDF untouched. A PDF page can hold JPEG and PNG data directly, so this tool embeds the original bytes rather than decoding and re-encoding them — the photo inside your PDF is the same data as the photo on your disk, with no generation loss.

The one exception is a rotated photo. Phones typically store the pixels sideways and add an EXIF tag telling viewers to rotate on display; embedding the bytes as-is would carry the pixels but drop that tag, so the page would come out on its side. The tool reads that tag — tested against JPEGs written both little-endian and big-endian, and against files with no tag at all — and only redraws an image when it actually needs turning. That redraw does re-encode the image and costs a little quality, so it is a trade made only when necessary; anything already upright is left alone, and the tool tells you which files it had to redraw.

WebP, HEIC and anything else outside JPEG and PNG has to be redrawn too, because a PDF simply cannot store those formats natively — that step is lossy by nature. If fidelity matters, feed it JPEGs or PNGs and let them pass through untouched.

Page size, margins and the fine print

Page size follows the image when you let it. With A4 selected and orientation set to Auto, a wide photo produces an 841.89 by 595.28 point page — A4 turned on its side — and a tall photo produces 595.28 by 841.89; choosing Portrait or Landscape overrides that per-image guess.

Fit to image is worth understanding before you pick it: the page becomes exactly your image's pixel dimensions read as PDF points, and a point is 1/72 of an inch. A 1200 by 900 image becomes a 1200 by 900 point page — about 16.7 by 12.5 inches — and a 4000-pixel-wide photo makes a page over 55 inches wide. It looks right on screen and prints wrong, so use A4 or Letter for anything headed to a printer.

Images are never stretched to fill the page — a small image keeps its true size instead of being blown up to cover A4, and a 4000 by 3000 photo on portrait A4 with the standard half-inch margin comes out centred at 523.28 by 392.46 points, shape intact; set the margin to None and it reaches the page edge instead. Two limits worth knowing: the output PDF is roughly as large as the images you feed it — ten 4 MB photos make around a 40 MB file, since nothing here compresses them — and because the conversion runs on the page's main thread, a big batch of large photos will pause the tab while it works. HEIC files from an iPhone may not open at all outside Safari.

Why is it free?

It runs entirely in your browser, so there is no server storing your images and no infrastructure cost to recoup from you. No account, no email gate, no paid tier hiding a feature you actually need.

There is no watermark either — PDF tools typically stamp their own name into the file's Producer metadata, but that is switched off here, and the output was checked: the field comes back empty. Free means the file looks like it came from nowhere but you.
