About Image2PDF

Our Mission

Image2PDF was created with a simple goal: to provide a fast, free, and completely private way to convert images into PDF documents. We believe that basic document tools should be accessible to everyone without requiring expensive software subscriptions, account sign-ups, or trusting third-party servers with your personal files.

Too many online PDF tools require you to upload your files to remote servers, where they may be stored, analyzed, or even shared with third parties. We took a fundamentally different approach. With Image2PDF, your files never leave your device. Every conversion happens right in your browser, using the power of modern web technology.

Whether you are a student scanning homework assignments, a professional compiling reports, or anyone who needs to turn images into a clean PDF document, Image2PDF is designed to make the process effortless.

How Our Technology Works

Image2PDF is built entirely with client-side web technologies. When you select images for conversion, they are read and processed using JavaScript APIs that run directly in your browser. The heavy lifting is done by pdf-lib, an open-source JavaScript library for creating and modifying PDF documents.

Here is what happens behind the scenes when you convert images to PDF:

1. File reading: Your browser reads the selected image files using the FileReader API. The images are loaded into memory on your device only.
2. Image processing: Each image is drawn onto an HTML Canvas element, which allows the tool to read pixel data and prepare the image for embedding into a PDF page.
3. PDF creation: The pdf-lib library creates a new PDF document, embeds each processed image into its own page, and applies your chosen settings (page size, orientation, scaling mode).
4. Download: The finished PDF is assembled as a binary blob in your browser memory and offered as a download. At no point does any data leave your device.

This architecture means that Image2PDF works even without an active internet connection after the page has loaded. It also means that conversion speeds depend on your device rather than network conditions, which is why conversions typically complete in seconds rather than minutes.

Privacy-First Approach

Privacy is not an afterthought at Image2PDF. It is the foundation of how the tool is built. Because all processing happens in your browser, we have designed the tool so that it is technically impossible for us to access your files. There is no server to intercept uploads because there are no uploads.

This makes Image2PDF especially suitable for sensitive documents: medical records, financial statements, legal paperwork, identification documents, and anything else you would not want to send to an unknown server. You can verify this yourself by opening your browser's developer tools and checking the Network tab during a conversion. You will see zero file upload requests.

Supported Formats

Image2PDF supports the most commonly used image formats:

• JPEG / JPG: The most widely used photograph format. Uses lossy compression to keep file sizes small while maintaining good visual quality. Ideal for photos and complex images with many colors.
• PNG: A lossless format that preserves every pixel perfectly. Best for screenshots, diagrams, text-heavy images, and graphics with transparency.
• WEBP: A modern format developed by Google that offers superior compression compared to JPEG and PNG. Supports both lossy and lossless compression, as well as transparency.
• BMP: An uncompressed bitmap format. Files tend to be very large, but they preserve exact pixel data without any compression artifacts.
• JFIF: A variation of the JPEG format commonly encountered in older systems and certain camera software. Image2PDF handles JFIF files the same way as standard JPEG files.
