Creating PDFs from Images: Layout, Page Sizing, and Print Preparation
PDF (Portable Document Format) is the universal standard for documents that must look identical on every device and printer. Creating a PDF from images is useful for combining multiple scanned pages into a single document, creating portfolios and lookbooks, preparing photo books for printing, archiving receipts and invoices, and sharing multi-image documents via email where uploading separate images would be inconvenient.
Page sizing is important for professional results. The most common page sizes are A4 (210×297 mm, standard in most countries), US Letter (8.5×11 inches, standard in the US and Canada), and A3 (297×420 mm, for larger prints). Our tool automatically fits images to the selected page size, maintaining aspect ratio so images are not stretched or distorted. You can choose between "Fit to page" (image fills the page with margins) and "Fill page" (image covers the entire page, cropping edges if necessary).
Image ordering and rotation are key to creating useful documents. When scanning multi-page documents with a phone camera, photos are often taken in different orientations. Our tool automatically detects portrait vs. landscape orientation and rotates images accordingly. You can also manually reorder pages by dragging them into the correct sequence before generating the PDF.
For print-quality PDFs, the source images should be at least 300 DPI at the target print size. A full-page image on A4 paper needs to be at least 2480×3508 pixels. If your images are lower resolution, they will still create a valid PDF but may appear pixelated when printed at full page size. Our tool preserves the original image quality in the PDF — no recompression or resolution reduction is applied.
How to Combine Images into a PDF Document
1
Add your images
Upload JPG, PNG, WebP, or BMP images. Drop multiple files at once — they appear as thumbnails in a sortable list. Add more images at any time.
2
Arrange page order
Drag and drop thumbnails to reorder pages. Rotate individual images if needed. Remove any images that should not be included.
3
Set page layout
Choose page size (A4, Letter, A3, or custom), orientation (auto, portrait, or landscape), and image fitting mode (fit within page or fill entire page).
4
Generate and download PDF
Click "Create PDF" to generate the document entirely in your browser. The resulting PDF is ready for printing, emailing, or archival.

Multiple Page Sizes
Support for A4, A3, US Letter, Legal, and custom dimensions. Different pages in the same PDF can use different sizes.
Lossless Quality
Images are embedded in the PDF at their original resolution and quality — no recompression is applied. What you put in is what you get out.
Automatic Orientation
Smart detection of portrait vs. landscape images with automatic rotation to match the page orientation.
Frequently Asked Questions
What is the maximum number of images I can combine?
This depends on your device's available memory. Each image is held in browser memory during PDF generation. Modern devices typically handle 50–100 high-resolution images without issues. For very large documents (200+ pages), consider processing in batches.
Will the PDF file size be smaller than the combined images?
No — the PDF file size is approximately equal to the sum of all image file sizes plus minimal overhead for PDF structure. PDF is a container format, not a compression tool. If you need a smaller PDF, compress your images first using our Image Compressor, then combine them into a PDF.
Can I add text overlay or annotations to the PDF?
This tool focuses on creating clean image-to-PDF conversions. For adding text, annotations, or form fields to a PDF, you would need a dedicated PDF editor. However, you can add text to your images using an image editor before combining them into the PDF.
Are the PDFs compatible with all PDF viewers?
Yes. The generated PDFs conform to the PDF 1.4 standard and are compatible with Adobe Acrobat Reader, Chrome's built-in PDF viewer, Apple Preview, Microsoft Edge, and all other standard PDF readers.
