Frequently Asked Questions
Which image formats are supported?
JPG, PNG, and WebP are all supported. Each image becomes one page in the output PDF.
Can I control the page size and orientation?
Yes — you can fit each image to A4 or US Letter, or use the original image dimensions as the page size. Portrait and landscape are automatically set based on the image aspect ratio.
Is there a limit on how many images I can add?
No server-side limit. You can add as many images as your device memory allows — dozens of photos convert smoothly on modern devices.
Will image quality be reduced in the PDF?
The tool embeds images at their original resolution. The PDF quality matches the input image quality. You can optionally adjust DPI settings before export.
Can I reorder images before creating the PDF?
Yes — drag and drop images to set the page order before clicking Create PDF.
Is my photo data uploaded to any server?
No — the entire conversion runs locally in your browser using the pdf-lib library. Your images never leave your device.
Detailed Guide
From a Stack of Images to One Clean PDF
A scanner saves each page as a separate JPEG. A phone camera shoots six photos of a handwritten form. A client needs eight portfolio shots in a single shareable file. In each case, converting images to a PDF solves the problem — one file, professional presentation, no app required.
This tool takes any number of JPG, PNG, or WebP images and combines them into a single PDF document. You control the page order. No watermark is added to your output. Nothing is uploaded anywhere.
Supported Image Formats
| Format | Notes |
|---|---|
| JPEG / JPG | Standard photo and scan format — fully supported |
| PNG | Lossless format — ideal for text-heavy scans, diagrams, and screenshots |
| WebP | Google's modern format — supported in all current browsers |
| HEIC / HEIF | Not directly supported — convert to JPEG in your phone settings first |
| TIFF | Not supported for multi-page TIFFs — extract individual frames first |
How the Conversion Works
Each image becomes a single page in the PDF. The page dimensions are matched to the image's natural aspect ratio — portrait images produce portrait pages, landscape images produce landscape pages. Nothing is cropped, letterboxed, or stretched.
Internally, the tool uses pdf-lib (a JavaScript PDF library) running in your browser:
- Each image file is read using the FileReader API and decoded into binary data
- Images are embedded directly into the PDF using
pdfDoc.embedJpg()orpdfDoc.embedPng() - Each page is sized to the image's pixel dimensions, then the image is drawn to fill it
- All pages are assembled into a single PDF and downloaded immediately
No image quality is lost in this process. What you put in is what the PDF contains.
Step-by-Step
