Merge JPG images into one PDF at their original quality, right in your browser.
Scanned pages, phone photos of documents, certificates, receipts: forms and email recipients usually want them as one PDF. This converter places each JPG on its own page and merges them into a single file, or makes one PDF per image if you prefer. JPG files are put into the PDF exactly as they are, byte for byte, so nothing is re-compressed and the PDF is ready in moments. PNG, HEIC, WEBP and AVIF images can be mixed in too. Everything runs in your browser; the images are not uploaded anywhere.
How to convert JPG to PDF
- Add the JPG images; drag the thumbnails into the order the pages should have and rotate any that came out sideways.
- Choose the page size: “Fit” (each page exactly the size of its image), A4 or Letter for printing and forms, and a margin of 0, 10 or 20 mm.
- Leave “One PDF” selected to merge everything, or pick “One PDF per image”, then convert and download.
What happens to quality, size and metadata
A PDF can store a JPG unchanged, and that is what we do: the compressed picture data goes into the PDF as it is, so the pages look exactly like your files and the PDF is only a few kilobytes larger than all the JPGs together. Rotation from the camera (the EXIF orientation flag) is applied by the page’s drawing instructions, not by re-encoding, so an upright phone photo stays upright without losing quality. If a photo carries a GPS location, the metadata segments are removed losslessly before it goes in. PNGs are stored losslessly; HEIC, WEBP and AVIF are converted to JPG at quality 92 first. Need a small file for an upload limit instead? Use a size page such as JPG to PDF under 300 KB.

JPG JPG is the lossy photo format standardised in 1992 as ITU-T T.81. It throws away detail the eye barely notices, and the quality setting decides how much. It has no transparency and no animation, but every phone, computer, browser, printer and upload form opens it.
PDF PDF is a page-based document format created in 1993 and an open ISO standard (ISO 32000) since 2008. Each page keeps its exact layout, fonts and images, so it looks the same on every device. A PDF can hold scanned photos, text, vector drawings and forms.

Without this site
Windows 10 and 11: select the images in File Explorer, right-click › Print (Show more options on Windows 11), choose the “Microsoft Print to PDF” printer and untick “Fit picture to frame” if you don’t want cropping. Mac: select the images in Finder, Control-click › Quick Actions › Create PDF. iPhone: select the images in the Files app and tap More (…) › Create PDF. Android: in Google Photos open an image, tap ⋮ › Print and pick “Save as PDF” as the printer; that does one image at a time.
Troubleshooting
- Pages are in the wrong order. Files are added in the order your device lists them. Drag the thumbnails, or name the files 01, 02, 03… before adding them.
- A page is sideways. Some scanners and older cameras don’t store rotation. Use the rotate button on that thumbnail; the picture itself is not re-encoded.
- The PDF is too large to upload. This page keeps original quality. For a portal limit, use JPG to PDF under 100 KB, 200, 300 or 500 KB, which compresses the images to fit.
- White borders around photos. That is A4 or Letter with a photo of a different shape. Choose “Fit” for pages that match each image exactly.
Questions and answers
How do I merge multiple JPG files into one PDF?
Add all the JPGs at once (or drop a whole folder on a computer), arrange the thumbnails in the right order and keep “One PDF” selected. Press Convert and you get a single PDF with one page per image. There is no limit on the number of images other than your device’s memory; dozens of phone photos are fine.
Does converting JPG to PDF lose quality?
Not here. The JPG data is copied into the PDF without decoding or re-compressing it, so every pixel is the same as in your file. Quality is only lost if you choose a size target (the “under N KB” pages), where the images are deliberately compressed to fit the limit you need.
How do I convert JPG to PDF on Windows without software?
Windows includes a PDF printer. Select the images in File Explorer, right-click and choose Print, pick “Microsoft Print to PDF”, set the layout and press Print, then name the file. It works, but you have fewer layout choices, and it may crop photos to fit the frame. This page does the same in the browser with page order, rotation and margins.
Is it safe to convert documents like ID cards to PDF online?
It depends on where the files go. This converter runs inside your browser: the images are never sent to a server, so a copy of your ID or certificate does not end up on anyone else’s computer. You can check it by turning on airplane mode after the page loads; converting still works.
