PDFConvertersOnline.comHow to convert JPG to PDF
- Choose your JPG images or drop them into the blue box.
- Drag the thumbnails into order and pick a page size and margin.
- Press Convert to PDF and save the file.
Your JPGs keep their original quality
A JPG is already a compressed file. Many converters decode it and compress it again when they build the PDF, and every extra round of JPG compression adds blur and blocky artifacts around text and edges. This converter avoids that. For normal JPG files it copies the original image data straight into the PDF, byte for byte, so the photo inside the PDF is identical to the one on your disk. That also keeps the PDF small: the finished file is usually only a few kilobytes larger than the images you added.
There is one exception. Phones often save a photo sideways and add a small note (the EXIF orientation tag) telling viewers to turn it when they show it. A PDF has no such note, so for these photos the tool draws the image upright first and saves it again at high quality. The result looks the way you see it in your gallery, not rotated.
Choosing a page size
| Setting | What you get | Good for |
|---|---|---|
| Same as image | Each page is exactly the shape of its photo, with no white borders unless you add a margin | Sharing on screen, portfolios, photo albums |
| A4 | 210 × 297 mm pages with the photo scaled to fit and centered | Printing in most countries, official forms |
| US Letter | 8.5 × 11 inch pages | Printing in the United States and Canada |
With A4 or Letter, Automatic orientation turns each page to match its photo: wide pictures get a landscape page and tall ones a portrait page. Pick Portrait or Landscape if every page must face the same way, for example when you print a booklet.
In Same as image mode the tool treats 96 pixels as one inch, so a 1920-pixel-wide picture becomes a 20-inch-wide page. PDF readers zoom to fit, so this looks normal on screen; if you plan to print, A4 or Letter is the safer choice.
Typical jobs
- Receipts and expense reports: photograph each receipt, add them all and send one PDF to accounting instead of a dozen attachments.
- Homework and handwritten notes: teachers and online classes often accept only a single PDF. Use A4 or Letter with a small margin so nothing is cut off when it is printed.
- Documents for applications: an ID card, a certificate and a signed page can go into one file in the order the form asks for.
- One PDF per photo: untick Put all images into one PDF and you get a separate PDF for every image, packed in a ZIP.
Other image types work too
You don't have to convert anything first. PNG, WebP, HEIC, AVIF, GIF and BMP files can go into the same PDF as your JPGs. Screenshots and graphics are usually PNG files, and PNG to PDF explains how transparency is handled. Photos straight from an iPhone are often HEIC; see HEIC to PDF. When the PDF is ready you can merge it with other PDFs or number its pages.

Frequently asked questions
Will the PDF look blurry?
No. Regular JPG files are placed into the PDF without being compressed again, so they keep exactly the sharpness they had. Only sideways phone photos and non-JPG formats are redrawn, at high quality.
How many photos can I put into one PDF?
There is no set limit. Everything runs on your device, so very large batches depend on its memory. A few hundred phone photos is usually fine on a computer; on a phone, try batches of about 50.
Are my photos uploaded to a server?
No. The PDF is built inside your browser tab and saved directly to your device. Your pictures are never sent anywhere.
Can I change the order of the pages?
Yes. Drag the thumbnails, use the arrow buttons on each image, or press Sort A–Z to order them by file name. The first thumbnail becomes page 1.
Why is one of my photos turned the wrong way?
Some cameras store the rotation in a way browsers can't read. Turn the photo with Rotate Image first, or rotate the finished page with Rotate PDF.
