Convert JPG to PDF

Turn JPG images into a PDF — one file or a whole batch merged into a single, ordered document — without your files ever leaving this device.

How to convert JPG to PDF

Drop your JPG files onto the panel above, pick a page size, and press Convert. Multiple images merge into one PDF, a page per image, in the order of the strip.

Page size is the only decision. Fit image makes each page exactly the shape of its image, with no borders and no scaling. A4 and Letter centre the image on a standard sheet with half-inch margins and rotate the page automatically for landscape photos, so nothing is squeezed to fit. The preview on the stage is the actual PDF rather than an approximation of it, so what you see there is what downloads.

The document is assembled entirely in your browser. Nothing is uploaded, which matters for precisely the things that end up as PDFs: identity documents, signed contracts, medical records, and bank statements.

Why convert JPG to PDF?

JPG photos become PDFs for one main reason: something demands a document.

Application portals, expense systems, court filings, and university admissions want "a PDF", even when what you actually have is a photo of a receipt, a signed form, or an ID. Converting wraps your photo in the document container those systems validate — and a whole set of photos becomes one multi-page PDF, which is how a photographed contract should arrive.

Image quality inside the PDF

JPG is already the format PDFs carry images in, so your photo goes in essentially as-is — embedded at quality 92, a visually lossless setting.

The PDF is typically about the same size as the JPGs that went in.

Page order is the strip order at the bottom of the tool — drag files in the order you want the pages, or add them one batch in sequence. The first page you see in the preview is exactly what the recipient opens.

Choosing a page size

Pick Fit image when the PDF is a wrapper, and A4 or Letter when it is a document someone will print or file.

The distinction is about what happens to the whitespace. Fit image gives the page the exact dimensions of your image, so there are no borders and nothing is scaled — ideal on screen, and the right answer when a system just wants the file in PDF form. A standard sheet instead places your image on a fixed page with margins, which is what makes a stack of photographed pages look like a document rather than a pile of photos.

Page sizeWhat it doesUse it for
Fit imageThe page is the image — exact dimensions, no borders, no scalingScreenshots, single photos, anything viewed on screen
A4Image centred on a 210 × 297 mm page with half-inch marginsDocuments headed for print or formal submission outside the US
LetterImage centred on an 8.5 × 11 in page with half-inch marginsDocuments for US recipients and US-format filings
On A4 and Letter, landscape photos get landscape pages automatically: the page rotates rather than the photo, so nothing ends up sideways.

Frequently asked questions

How do I merge photos into one PDF?

Drop them all in at once. The whole batch becomes one PDF with a page per photo, in the order of the filmstrip — which is how a multi-page document (a photographed contract, several receipts, a scanned notebook) is expected to arrive. One photo in, one page out; twenty photos in, one twenty-page PDF out.

One PDF or several?

One. The whole batch merges into a single PDF with a page per image, in the order shown in the strip — which is what a multi-page document should be. To get separate PDFs instead, convert the files one at a time.

Does converting JPG to PDF reduce quality?

JPG is already the format PDFs carry images in, so your photo goes in essentially as-is — embedded at quality 92, a visually lossless setting. The PDF is typically about the same size as the JPGs that went in.

Is it safe for sensitive documents?

The conversion runs as code inside your browser tab — the files never leave your device, there is no server copy, and the tool keeps working with your connection switched off. For IDs, contracts, and medical paperwork, that is the property to insist on.
