JPG is the format of photos, from phone cameras to receipts saved by an office copier. A folder of JPGs is awkward to send, print in order or attach to a form that expects one document. JPG to PDF places each photo on its own page in the order you arrange, and it keeps the original image data, so the PDF looks exactly like the photos you started with.
How to use JPG to PDF
- Add one or more JPG images. You can add more later and they join the list.
- Drag the files into the order you want the pages to appear.
- Select Convert to PDF.
- Download the PDF, which is named after the first image.
Why the photos aren't recompressed
- Each re-save loses detail: Each time a JPEG is decoded and saved again it loses a little more detail, like a photocopy of a photocopy.
- The original data is placed as it is: When an ordinary JPG needs no changes, VelloDoc places the original compressed image data straight into the PDF instead of re-encoding it. The photo inside the PDF is therefore identical to the file you uploaded, and the PDF is roughly the combined size of the photos.
- If you need it smaller, Compress PDF can reduce resolution deliberately afterwards.
Orientation and page size
- Sideways photos are turned upright: Phones often store a photo sideways and record how it should be turned in a hidden orientation tag. VelloDoc reads that tag and turns the image upright before building the page, so portrait shots don't arrive on their side.
- Those are re-encoded once: Those photos are re-encoded once at high quality.
- Page size from pixel dimensions: Each page is sized from the image's pixel dimensions at 150 pixels per inch, so a large camera photo makes a large page. Viewers fit it to the screen, and printers scale it to the paper.
Photos of documents
- Pictures of text, not text: If the JPGs are photos of paper pages, the PDF contains pictures of text instead of text.
- Add a searchable layer with OCR PDF, straightening crooked shots with Deskew PDF first.
- To capture pages directly with a phone camera, Scan to PDF opens the camera for you.
- Where to read more: The guide to choosing formats explains when to keep photos as JPG and when a PDF serves the reader better.
When people use JPG to PDF
Receipts and invoices as one file
Combine photographed receipts into a single PDF that an expenses system or accountant can review in order.
Photo evidence for a claim
Send an insurer or landlord one document of dated photos instead of a stream of separate attachments.
Portfolio samples
Present artwork or project photos as one file that opens on any device, in the sequence you choose.
Limitations to know
JPG to PDF places one image per page, sized to the photo or to a paper size you choose, with an optional margin. It doesn't crop, enhance or read text in photos, and images larger than 6,000 pixels on a side are scaled down.
JPG to PDF: common questions
Will my photos lose quality?
Standard JPGs are embedded without recompression, so they keep exactly the quality they had. Photos that need turning upright, CMYK JPGs and images over 6,000 pixels on a side are re-encoded once at high quality.
Can I mix JPG and PNG images in one PDF?
Yes, this tool accepts other image types too. Any Image to PDF is for mixed formats, and both use the same conversion.
How many photos can I add?
As many as fit within the upload limit, which is 80 MB per job on a default VelloDoc server. Very large sets are easier to convert in batches and join afterwards with Merge PDF.
Why is the page so large when I print?
With Same as image, a page follows the photo's pixel dimensions at 150 pixels per inch, so camera photos make big pages. Choose A4 or Letter as the page size to fit every photo on a standard sheet.
