What is Images to PDF?
This tool turns one or more images — photos of documents, scans, screenshots, artwork — into a single PDF file, one image per page. PDF is the format the world’s bureaucracy speaks: application portals, expense systems, professors, and print shops all want “a PDF”, even when what you actually have is five phone photos of a contract.
What Does This Tool Do?
Drop your images, arrange their order, pick a page size, and download the PDF — assembled entirely in your browser with the pdf-lib library. Your images are never uploaded; the tool even works offline once loaded. JPEG and PNG embed directly; WebP, GIF, and BMP are converted automatically before embedding.
How to Use This Tool
- Drop images onto the box (or click to browse) — select several at once.
- Reorder with ↑ ↓ (the PDF follows the list order); remove any with ✕.
- Choose the page size:
- A4 pages — each image centered on a standard A4 portrait page with a margin. The right choice for documents you’ll print or submit.
- Page = image size — each page exactly matches its image’s dimensions, edge to edge. The right choice for artwork, screenshots, and digital-only PDFs.
- Click Create PDF and download
images.pdf.
Photographing Documents That Convert Well
Most images headed for PDF are phone photos of paper. A few habits make the result dramatically better:
- Fill the frame — crop to the paper’s edges before converting; A4 mode will scale whatever you give it, stray desk background included.
- Flatten the page and shoot from directly above — perspective skew is the difference between “scanned” and “photographed”.
- Prefer even, indirect light — flash creates a hotspot that can make text unreadable when printed.
- Use your camera app’s document mode (or the crop-and-straighten tools) if it has one; it handles deskewing automatically.
- Mind the file size: a 10-photo PDF of 4 MB photos is a 40 MB PDF. Run photos through our Image Compressor first if the PDF must fit an upload limit.
JPEG or PNG Inputs?
For photos of documents, JPEG produces far smaller PDFs at equal readability — the PDF embeds the image bytes as-is, so the input size is the page size. PNG is the right input for screenshots and graphics with sharp text, and it’s what transparency-bearing images should use (transparent areas render over white on the PDF page). Either way the conversion itself is lossless: whatever quality your image has is exactly what lands in the PDF.
Frequently Asked Questions
Are my images uploaded to a server?
No. The PDF is assembled in your browser’s memory — no image ever leaves your device. Load the page, disconnect from the internet, and it still works.
Can I mix different image formats in one PDF?
Yes — JPEG, PNG, WebP, GIF, and BMP can be combined freely. Non-JPEG/PNG formats are converted automatically (GIFs contribute their first frame only).
Why is my PDF so large?
The PDF contains your images at their original size — ten 5 MB photos make a ~50 MB PDF. Compress the images first (our Image Compressor at ~80% quality typically cuts photos by 70–90%) and the PDF shrinks proportionally.
Is the text in my photographed document searchable?
No — the PDF contains pictures of text, not text. Making it searchable requires OCR (optical character recognition), which is a different, heavier process. For submissions and archives, image PDFs are almost always accepted.
Can I put multiple images on one page?
Not in this tool — it’s deliberately one image per page, which covers the document-scan use case. For photo-collage layouts, arrange the images in a slide or document editor and export that as PDF.
What happens to EXIF rotation from phone photos?
Photos are embedded with their stored pixel orientation. If a photo appears sideways in the result, rotate it in your gallery app (which rewrites the pixels) and re-add it — or run it through our Image Resizer, which applies EXIF rotation during processing.
