Converting images into a PDF is one of the most common tasks for anyone managing physical documents in a digital workflow. Photos taken with a smartphone of a signed contract, insurance documents, or handwritten notes become a professional shareable PDF in seconds. Photographers can package a set of portfolio images into a single PDF for gallery submissions or client review. Teachers can compile a set of scanned worksheet images into one PDF for distribution. Architects and engineers can bundle a set of diagram photos or hand-drawn sketches into a single document for archiving. LazyPDF's Image to PDF tool handles all of these cases with a simple drag-and-drop interface that supports JPG, JPEG, and PNG files. Add as many images as you need and arrange them in the desired order before converting. Each image is placed on its own page, sized to match the image's original aspect ratio, so nothing is cropped or distorted. The conversion runs entirely in your browser using pdf-lib — your images are never uploaded to any server, which matters for personal photos, medical imaging files, identity documents, or any other images with privacy sensitivity. The output PDF is a clean, standards-compliant document that can be opened on any device, emailed, printed, or archived without compatibility concerns. For anyone who regularly receives image-based documents that need to be compiled and submitted as PDFs, this tool eliminates the need for desktop software entirely.

How It Works

Image to PDF takes one or more image files and embeds each as its own page in a new PDF document constructed by pdf-lib running in your browser. The tool reads each image file, determines its pixel dimensions, creates a PDF page sized to match those dimensions exactly — preserving the original aspect ratio — and embeds the image data into the page. JPG images are embedded using JPEG compression natively; PNG images are embedded with their full color and transparency data. You can reorder the images by dragging them before conversion to control the final page sequence. The complete PDF is assembled in memory in your browser and offered for download without any server involvement.

Key Features

Multiple Images Per PDF

Add as many images as you want — each is placed on its own page in the resulting PDF document in the order you specify.

Drag to Reorder

Rearrange images before conversion by dragging them into the sequence you want in the final PDF.

Auto Page Sizing

Each PDF page is automatically sized to match the exact pixel dimensions of its image, preserving the original aspect ratio with no cropping.

Complete Privacy

Conversion happens entirely in your browser using pdf-lib. No images or data are sent to any external server at any stage.

Frequently Asked Questions

What image formats are supported?

The tool accepts JPG, JPEG, and PNG images. These cover the vast majority of image formats encountered in professional and personal workflows. For images in TIFF, BMP, or HEIC format, convert to JPG or PNG first using any image editor or the Photos app on your device.

Does converting images to PDF reduce quality?

No. Images are embedded into the PDF at their original resolution and quality using efficient PDF image embedding. The PDF acts as a container for your images without recompressing them. The resulting file size is approximately equal to the combined size of the input images.

Can I create a single page with multiple images?

Currently each image is placed on its own full page. For a collage or multiple images on one page, arrange them in an image editor and save as a single composite image first, then convert that single image to PDF.

Is there a limit on how many images I can convert?

There is no imposed limit. Since all processing happens in your browser, the practical limit is your device's available memory. Most devices handle dozens of high-resolution images in a single conversion. A set of 50 high-resolution photos should convert without issues on a modern device.

Will the resulting PDF be text-searchable?

No. Image-based PDFs do not contain searchable text — the images are pixel data. If you need the text content to be searchable, first convert your images to PDF with this tool, then run the output through the OCR tool to extract the text as a separate file.

Can I add images from my phone's camera roll?

Yes. Mobile browsers on iOS (Safari) and Android (Chrome) let you select images from your camera roll or photo library. The images are loaded into the browser and converted entirely on your device without uploading to any server.

What is the output PDF file size compared to the input images?

The PDF file size closely matches the total size of your input images. For a collection of 10 images totaling 15 MB, expect a PDF of approximately 15–16 MB. PDF image embedding adds minimal structural overhead without significantly recompressing the image data.

Can I add images from documents or screenshots?

Yes. Any image file — screenshot, photograph, scanned document, diagram export, or graphic — can be converted to PDF using this tool. This is useful for compiling screenshots, product photos, or exported charts into a single shareable PDF document.

Will transparent PNG images have a white background in the PDF?

PDF pages have a default white background. Transparent areas in PNG images will appear against the white page background in the resulting PDF. The transparency data is technically preserved in the PDF's image stream, but the white page shows through transparent pixels visually.
