Bundle JPG images into a single multi-page PDF

Now that your images are in PDF form, you might want to add page numbers, insert a cover page, or make the text searchable. Adobe Acrobat lets you edit the resulting PDF as if it were a living document rather than a flat image stack. (We may earn a commission, at no cost to you.)
Why use JPG to PDF
- Combines a batch of photos into one paginated PDF anyone can open -- no special viewer needed.
- JPEG data goes into the PDF byte-for-byte. No re-compression, no quality loss.
- Drag-and-drop reordering before conversion. Fix the sequence now instead of rearranging in a PDF editor later.
- Pages scale to each image's aspect ratio, so nothing gets cropped or stretched.
How it works
pdf-lib creates a new PDFDocument and processes each uploaded image in sequence. For JPEGs, embedJpg() reads the binary data, pulls dimensions from the SOF (Start of Frame) marker, and embeds the compressed stream directly as an XObject image -- no decode/re-encode cycle, so quality is preserved byte-for-byte. For PNGs, embedPng() decompresses the IDAT chunks and embeds the pixel data using FlateDecode. A new page is added per image, sized to the image's aspect ratio with A4 as the default, and the XObject is drawn onto the page's content stream at the calculated position and scale. The assembled document is serialized and downloaded as a single file.
About this tool
Got a stack of receipt photos that need to be one file? Or product shots that belong in a catalog? Upload your JPGs, drag them into the right order, and download a single PDF with one image per page. Every step happens locally -- no server ever sees your photos. JPEG data is embedded directly into the PDF stream without re-encoding, so there is zero quality loss. PNG files with transparency work too. Each image gets its own page, scaled to fit the page dimensions while keeping the original aspect ratio intact -- nothing gets cropped or stretched. Drag-and-drop reordering is the key feature here. Phone cameras don't always name files in the order you shot them, and batch scanners can jumble the sequence. Rearranging before conversion saves you from doing it after the fact in a PDF editor. The output is a standards-compliant PDF that opens in Preview, Chrome, Adobe Reader, or any other viewer. A progress indicator tracks each image so you know when a large batch is ready.
How to use JPG to PDF
- Drop your images. Drag JPGs onto the upload area or click to browse. Upload as many as you need.
- Arrange the order. Drag thumbnails into the page sequence you want.
- Click Convert. The PDF builds and downloads automatically.
Use cases
- Packaging 30 headshot JPGs into a single PDF lookbook for a modelling agency submission.
- Combining job-site inspection photos into a PDF report attached to a safety compliance form.
- Scanning a child's hand-drawn artwork as phone photos, then assembling them into a keepsake booklet.
- Converting scanned insurance card images into one PDF for upload to an electronic health records system.
- Bundling product photography into a PDF catalog for wholesale buyer outreach.
- Turning whiteboard photos from a brainstorm session into a single PDF that's easy to share with remote team members.
Frequently Asked Questions
No. JPEG data is embedded byte-for-byte into the PDF stream -- no re-encoding happens. What goes in is exactly what comes out.
JPG/JPEG and PNG. PNGs with transparency are handled correctly using FlateDecode.
Yes. After uploading, drag the thumbnails into whatever sequence you want. The PDF pages follow that exact order.
There's no pixel-dimension cap. The practical limit is your device's available memory. A batch of 50 phone photos (3-5MB each) converts without issues on most laptops.
Each page is sized to match the image's aspect ratio, defaulting to A4 dimensions. The image scales to fit within the margins without cropping.
Yes. The output follows the PDF standard and works in Preview, Chrome's built-in viewer, Adobe Reader, and every other mainstream PDF app.
