About this free image to PDF tool
Image to PDF is a free online tool that turns images into a single PDF, directly in your browser. JPG, PNG, and WebP all work in the same drop. There is no signup, no upload, and no watermark. Each image is decoded on your device using the browser's native image APIs, then assembled into a PDF with pdf-lib. The PDF never travels to a server.
One tool for whatever format your images are in
A typical photo dump from a phone is JPG. A typical screenshot is PNG. A typical export from a modern web app is WebP. When you have a mix, you do not want to convert them all to one format first and then make a PDF. You want to drop the whole batch and get one PDF.
That is what this page does. The tool reads each file, identifies the format, picks the right embed path, and places each image on its own page in the order you set. The output is one PDF, regardless of the formats that went in.
What each format brings to the PDF
JPG is the default for phone photos and digital cameras. The format is lossy but optimized for photographic content. EXIF orientation is read so a portrait photo stays portrait in the PDF.
PNG is the format for screenshots, scans, signature exports, and design mockups. PNG is lossless. Transparent PNGs are composited onto white before embedding so the page stays consistent in every PDF reader.
WebP is Google's modern image format. Many websites export WebP by default in 2024 and 2025. WebP files are smaller than the equivalent JPG. We re-encode WebP as JPEG before embedding because PDF readers do not all support WebP natively.
Three page-size options for any output
Fit to image sizes each page exactly to the image, with no margin. Best for digital sharing. Each page is the shape of its image.
A4 (210 by 297 mm) is the page size used outside the United States. The image is centered with a small uniform margin and the page rotates between portrait and landscape based on the image aspect. Pick A4 for school submissions, government forms, banking, or anything going to a European, Asian, or African recipient.
Letter (8.5 by 11 inches) is the page size in the United States and Canada. Same centering and auto-rotation rules as A4. Pick Letter for North American printing.
Image to PDF on every device
The tool runs in any modern browser. On Windows or Mac, drag images from File Explorer or Finder onto the dropzone. On a Chromebook, drag from the Files app. On iPhone, iPad, and Android, tap the dropzone and the system file picker opens. Pick from the Photos app, Files, iCloud Drive, Google Drive, Dropbox, or any other provider installed.
HEIC photos from newer iPhones are not yet supported. The iOS Photos app gives you the option to export as JPEG when you share, so use that as the workaround.
Privacy in plain language
Every byte of work happens on your device. Images are decoded in memory by the browser, drawn into a hidden canvas when needed, and assembled into a PDF using a JavaScript library that ships with the page. No part of any image is sent over the network. You can confirm this in your browser by opening the Network tab before you convert. Closing the tab removes everything.

Frequently asked questions
Is Image to PDF really free?+
Yes. Completely free, forever. No signup, no watermark, no daily limit, no upgrade prompt.
Which image formats are supported?+
JPG, JPEG, PNG, and WebP. You can mix all four extensions in the same conversion. HEIC photos from new iPhones are not yet supported, but the iOS Photos app can export them as JPEG before you share.
Are my images uploaded anywhere?+
No. The conversion runs entirely in your browser using pdf-lib. Your images never leave your device. You can confirm this by checking your browser Network tab.
Can I combine multiple images into a single PDF?+
Yes. Drop as many images as you want (up to 20 per batch, 100 MB combined). Drag the rows to set the page order, pick a page size, then click Convert. The output is one PDF.
What is the maximum file size and image count?+
Up to 20 images per conversion, 100 MB combined. The limits keep conversion fast and keep browser memory under control on phones and older laptops. Convert in two batches if you hit the cap.
Does the order of images in the file list matter?+
Yes. The first row in the file list becomes page 1, the second row page 2, and so on. Drag the rows to reorder before you click Convert.
Will my images lose quality during conversion?+
JPG files are embedded with minimal re-encoding to preserve sharpness. PNG without transparency is also preserved as is. PNG with transparency and WebP are re-encoded as JPEG at quality 0.92, which is visually lossless for nearly all images.
Why is my phone photo rotated correctly here but sideways in other converters?+
Phone cameras save the photo in a fixed orientation and add an EXIF tag describing how to display it. This tool reads that tag and rotates the image correctly. Many older converters ignore the tag and produce sideways pages.
How do I convert multiple images to one PDF on Windows?+
Open this page in Edge, Chrome, or Firefox. Drag the images from File Explorer onto the dropzone, set the order by dragging rows, pick a page size, then click Convert. The PDF lands in your Downloads folder.
How do I convert images to PDF on a Mac?+
Open this page in Safari, Chrome, or Firefox. Drag the images from Finder onto the dropzone, reorder if needed, pick a page size, then click Convert. The PDF saves to your Downloads folder.
