Questions
JPG to PDF — FAQ
Everything you need to know about converting JPG and JPEG images to PDF.
Yes, completely free. No hidden plans, no watermarks, no credit card required. Convert unlimited JPG and JPEG images to PDF at no cost, with no daily limits like Smallpdf or iLovePDF impose.
Yes. Your JPG is embedded in the PDF at full resolution with no additional compression. The image inside the PDF looks exactly as sharp and detailed as your original photo. No quality loss, no recompression artifacts.
Yes, you can drop as many JPG files as you want. Currently, each image gets its own individual PDF file (one JPG becomes one PDF). If you need to merge multiple JPGs into a single PDF, you can combine the output PDFs with any free PDF merger.
100% private. Your images are processed entirely inside your browser using JavaScript. They never upload to any server, never touch the cloud. This makes PDFduck safe for sensitive images like scanned IDs, medical documents, financial receipts, or personal photos.
Each JPG can be up to 50 MB. Since the conversion happens on your device, the real ceiling is your browser's available memory. Modern phones and computers handle 50 MB images easily.
Yes. JPG and JPEG are the same format with different extensions — both are fully supported. Whether your file ends in .jpg or .jpeg, just drop it onto the converter and it works.
Yes. PDFduck works on iPhone, iPad, and Android devices through your mobile browser. No app download needed. Perfect for converting phone photos, screenshots, or scanned receipts directly from your mobile gallery.
Just drop your scanned JPG onto the converter. If you scanned with your phone's camera app or a scanner app that saves as JPG, the image will convert to a clean A4-sized PDF. For multi-page scans, convert each page separately, then merge the PDFs together.
Yes. The PDF is generated at A4 page size with your image scaled to fit perfectly. The original resolution is preserved, so prints stay crisp. Great for printing photos, receipts, tickets, or ID scans.
Smallpdf limits free users to 2 conversions per day and uploads your images to their servers. iLovePDF has similar restrictions. PDFduck has no daily limits, no sign-up, and converts entirely in your browser — your photos never leave your device. This matters a lot if you're converting sensitive images like ID scans or private photos.

The complete JPG to PDF guide
Why convert JPG images to PDF, when it's useful, and how to get the best results from your conversions.
Why convert JPG to PDF?
JPG (or JPEG) is the world's most common image format — your phone photos, screenshots, and scanned documents are usually saved as JPG. But there are situations where PDF is a much better choice for sharing, submitting, or archiving those images:
Professional submission — Universities, employers, and government portals typically require PDF uploads. A JPG of your ID or receipt may get rejected even if the content is clear.
Consistent printing — A PDF prints the same way on every device and printer. JPGs can behave unpredictably depending on your printer settings and image size.
Universal compatibility — Every device and operating system can open a PDF with built-in readers. Not all apps handle JPGs the same way (some auto-rotate, others don't).
Organized archiving — PDFs are the long-term storage standard. JPGs from old phones may lose metadata or quality over time, while PDFs stay stable for decades.
Harder to edit — A PDF is less likely to be edited accidentally, which matters for documents like contracts, agreements, or legal evidence.
Common uses for JPG to PDF conversion
Here are the most frequent scenarios where converting JPG to PDF is exactly what you need:
Scanned IDs and passports — When applying for visas, bank accounts, or online services, upload a clean PDF instead of a raw phone photo.
Receipt submission — Many expense systems (Concur, Expensify, company portals) require PDF receipts. Take a photo, convert, upload.
Photo of a signed document — Signed a paper contract? Snap it, convert JPG to PDF, send it back professionally.
School and university assignments — When your homework is on paper, photograph it and convert to PDF before submitting on Moodle, Canvas, or Blackboard.
Medical records and prescriptions — Convert doctor's notes or prescriptions to PDF for insurance claims or sharing with other clinicians.
Whiteboard and notebook photos — Meeting notes, lecture snapshots, and brainstorm sessions captured on your phone → clean PDFs.
Photo collections for clients — Photographers often deliver proofs as PDFs because they're easier to annotate and review than individual JPG files.
Tickets and boarding passes — Some venues only accept PDF tickets, not phone screenshots.
JPG vs. PDF: what's the difference?
People often ask whether they should use JPG or PDF, and the answer depends on what you're doing with the file. Here's a quick breakdown:
JPG (or JPEG) is a compressed image format designed for photos. It handles colors and gradients efficiently, producing small files with acceptable quality. However, JPG is a lossy format — every time you save or edit, a bit of quality is lost. JPGs also don't support transparency or vector graphics.
PDF (Portable Document Format) is a container format that can hold text, images, vectors, and interactive elements all in one file. A PDF can include one or multiple pages, each page can contain anything from a plain JPG to a complex layout. PDFs are designed to look identical everywhere they're opened.
Rule of thumb: Use JPG when you're editing, posting online, or sending to someone who'll view the image. Use PDF when you're submitting, printing, archiving, or sending to someone who'll open it professionally.
How browser-based JPG conversion works
Traditional online JPG to PDF converters — Smallpdf, iLovePDF, jpg2pdf, Adobe Acrobat online — all follow the same pattern: you upload your image to their server, they generate a PDF in the cloud, and send it back to you. That means your photo sits on a third-party server for at least a short time, logged and potentially analyzed.
PDFduck works differently. When you drop a JPG onto the page, your browser's built-in image decoder reads it directly from your device. The image data is then written into a PDF structure using JavaScript, all locally. The resulting PDF is generated entirely on your computer or phone — no data is sent anywhere.
This approach has three big wins: privacy (nobody sees your image but you), speed (no upload or download time), and no limits (nothing caps your usage since there's no server cost to us per conversion).
Tips for the best JPG to PDF results
Use good lighting when photographing documents — Avoid shadows and glare. Natural light from a window works best. Bad lighting means a bad PDF, no matter how good the converter is.
Shoot perpendicular to the page — Hold your phone flat and parallel to the paper. A tilted photo makes a tilted PDF.
Crop your JPG before converting — Trim away the background, desk, or clutter around your document so the PDF contains only what matters. Phone photo editors and apps like Photos or Snapseed make this easy.
Higher resolution is not always better — A 10 MB photo of a receipt is overkill. 2–5 MB JPGs produce perfectly readable PDFs at much smaller file sizes.
Consider orientation — Rotate your JPG to the correct orientation in your phone's photo app before converting. PDFduck preserves the orientation you give it.
For multi-page scans — If you're scanning a multi-page document, name your files in order (page1.jpg, page2.jpg...) and convert them in sequence. Then use a PDF merger to combine them.
JPG vs. PNG for PDF conversion
You may see both JPG and PNG options on converter sites and wonder which to use. Here's the quick answer:
JPG is better for photos — Real-world photos with lots of color variation compress efficiently in JPG format. Smaller files, good enough quality.
PNG is better for screenshots, logos, and graphics — Anything with sharp edges, text, or flat colors (UI screenshots, diagrams, logos) stays crisp in PNG but gets blurry in JPG.
Both work with PDFduck's converter. If you're not sure which you have, just drop the file — it works with whatever it gets. For dedicated PNG conversion with guidance tailored to that format, see our guides on the main page.
