About PDF to Image
PDF to image is a small, free utility for turning PDF pages into ordinary image files. It was built around a single constraint: the document should never leave the visitor's device.
What this site does
The site offers one tool. You give it a PDF, it renders each page, and it gives you back a ZIP archive of PNG, JPG or WEBP images. You can control the output resolution, the encoder quality for lossy formats, and how tightly the archive is packed.
There is no account system, no paid tier and no usage limit. The tool does not store your files because it never receives them in the first place.
How the conversion works
PDF rendering is handled by PDFium, the open source rendering engine that also powers Chrome's built-in PDF viewer. It is compiled to WebAssembly and loaded by your browser alongside the page, which is why there is a short loading indicator the first time you arrive.
When you select a file, the browser reads it into memory and hands the bytes to PDFium. Each page is drawn onto an off-screen canvas at the scale you chose, encoded by the browser's own image encoder, and appended to a ZIP archive built in memory. The finished archive is handed to the browser as a download. Every one of those steps happens on your machine.
The application itself is written in Rust using the Leptos framework, which is what makes it practical to run a real PDF engine client-side while keeping the page small.
Who runs it
PDF to image is an independently operated site based in Japan. It is funded by advertising, which is what keeps the tool free and unlimited for everyone.
