What Is an Image to PDF Converter?
An image to PDF converter combines one or more images — photos, scans, screenshots, or graphics — into a single, portable PDF document. Each image becomes one page in the resulting file, which can then be viewed, printed, signed, or shared as a standard PDF rather than a folder of separate image files.
Browser-based converters like this one process everything locally using the Canvas API to render and compress images, and the pdf-lib JavaScript library to assemble the final PDF — meaning your photos are never uploaded to a remote server. This makes it ideal for converting scanned IDs, personal photos, receipts, or confidential documents into a single shareable file.
How to Convert Images to PDF
Upload your images
Drag and drop multiple JPG, PNG, WebP, GIF, or BMP files into the drop zone, or click to browse. Add more images at any time.
Arrange your pages
Drag any thumbnail to reorder it, or use the arrow buttons. The order shown matches the final page order in your PDF.
Rotate if needed
Click the rotate icon on any image to fix sideways or upside-down photos before converting.
Choose page settings
Pick 'Fit to Image' to match each page to its photo's dimensions, or select A4, Letter, or A3 for a standard document size with custom margins.
Convert and download
Name your file, set your preferred quality level, and click Convert to PDF. The file is generated instantly and downloads automatically.
Choosing the Right Page Size & Quality
Page Size Guide
- Fit to Image — best for photo albums and image galleries; no white borders
- A4 — best for documents, scans, and international printing
- US Letter — best for documents printed in the United States and Canada
- A3 — best for posters, diagrams, and large-format prints
Quality Guide
- Original — no compression; best for archival or print-quality output
- High — minimal visible quality loss; good default for most uses
- Medium — noticeable file size reduction; good for sharing via email
- Low — smallest file size; best for many images or web-only sharing

Frequently Asked Questions
Technical note: Images are rendered through an HTML canvas (applying any rotation) and re-encoded as JPEG before being embedded into the PDF using pdf-lib. PNG transparency is flattened onto a white background since standard PDF pages do not support alpha transparency. For pixel-perfect archival quality, select "Original" quality, which applies minimal JPEG compression.
