Convert JPG to PDF (Free, No Upload)

Turn one or more JPG photos into a single PDF. Everything runs on your device; files are never uploaded.

Each image becomes one PDF page, in the order below.

Files are processed on your device. Nothing is uploaded.

What this tool is for

JPG is the format of things you photograph: receipts on a desk, a signed form you couldn’t scan properly, whiteboard notes after a meeting, pages of a paper document captured one by one with your phone. Plenty of systems that accept those things want a PDF, and ideally one PDF, not fourteen attachments. Expense systems are the canonical example: a week of travel produces a pocketful of receipts, and finance wants a single file.

So that’s what this does. Add your JPGs, drag them into the right order, and build. Each image becomes one PDF page sized exactly to the image, and the whole thing downloads as images.pdf. The conversion happens in your browser using the open-source pdf-lib library, which means a photo of your signed lease or your medical bill is never uploaded anywhere.

The honest details

Each JPG is embedded as-is, with no recompression. That’s good news for quality, since nothing is degraded, and mixed news for file size, since the PDF weighs about what the source photos weigh. Pages match the image’s pixel dimensions at 96 pixels per inch (the tool multiplies pixels by 0.75 to get PDF points), and there’s no page-size or margin option at launch. For receipts and document photos headed to an expense system or an email thread, that’s exactly right. For a print-ready letter-size layout with margins, it isn’t, and we’d rather say so than surprise you.

Source imagesResulting PDF
8 receipt photos, ~2 MB each8 pages, ~16 MB
Same 8 photos compressed first8 pages, often 3–5 MB
4 phone scans of a contract4 full-quality pages, in your order
Mixed portrait and landscape shotsEach page keeps its own orientation

Two practical tips fall out of that table. First, if the PDF needs to fit an upload limit, run the photos through the image compressor before converting; the PDF builder won’t shrink anything for you. Second, if an upload form demands specific dimensions, the image resizer handles that before the PDF stage too.

JPG or PNG source, and what comes next

Use this tool for photographs and camera scans. If your images are screenshots, diagrams, or anything with crisp text and flat colors, they’re probably PNGs, and the PNG to PDF tool is the matching path; converting a screenshot to JPG first would only smudge the text edges. Got a PNG that’s actually a photo? Turn it into a JPG with PNG to JPG and it’ll usually shrink dramatically before it ever reaches the PDF.

Once you have the PDF, the rest of the toolkit applies: combine it with other paperwork using the PDF merger, or pull out a page with the PDF splitter. One limitation to keep in mind: the output is pictures of text, not text. None of these tools do OCR, so the words in a photographed contract won’t be selectable or searchable in the PDF.

Frequently asked questions

Are my photos uploaded during conversion?

No. The PDF is assembled in your own browser with the open-source pdf-lib library. Your images are read into memory on your device, placed onto pages there, and the finished PDF downloads directly. Nothing is sent over the network, and the tool works offline once loaded.

Does converting reduce the quality of my JPGs?

No. Each JPG is embedded into the PDF exactly as-is, with no recompression. What you photographed is what ends up on the page, byte for byte.

What size will the PDF pages be?

Each page matches its image's dimensions exactly, at 96 pixels per inch. A 1,920 by 1,080 screenshot becomes a 20 by 11.25 inch page; a phone photo becomes a correspondingly large page. There's no page-size or margin option at launch, so if you need letter-size pages with white borders, this isn't the tool yet.

Can I put multiple receipts into one PDF, in a specific order?

Yes, that's the main event. Add as many JPGs as you like, reorder them before building, and each image becomes one page of a single PDF named images.pdf, in the order you set.

Why is the resulting PDF so large?

Because the JPGs go in untouched, the PDF weighs roughly what the images weigh. Ten 4 MB phone photos make a roughly 40 MB PDF. Shrink the photos first with the image compressor, then convert; the tool itself never recompresses.
