Deep dive
What is Image to PDF?
Image to PDF bundles JPG, PNG, and WEBP images into a single PDF, one image per page. It's the universal way to share a set of images as a single downloadable file that opens the same on every device.
FormatSwitch builds the PDF locally in your browser. The images and the finished PDF never touch a server, which matters for scanned IDs, medical images, or private photos.
When to use it
- Combine mixed JPG/PNG scans into one PDF.
- Attach a set of screenshots as a single PDF in email.
- Assemble a lightweight photo portfolio.
How to use it safely without uploading
Drop your images, arrange them in the right order, and press Convert. The PDF is generated in your browser and downloads immediately.
Browser-based vs server-based conversion
Most online converters upload your files to their servers, process them there, and then let you download the result. That means your file exists on someone else's computer, often in logs and backups, sometimes indefinitely. FormatSwitch is different: every conversion runs on your device using WebAssembly and the browser's built-in Canvas and PDF engines. Your file never leaves your computer, so there is nothing to leak, nothing to subpoena, and nothing to trust us on — the code that does the work is running right in your tab.
FAQ
Image to PDF — questions people ask
- Are the images uploaded?
- No. Files are processed entirely in your browser using WebAssembly and the Canvas API. Nothing is uploaded to a server, and no copy is kept once you close or refresh the tab.
- Which formats are supported?
- JPG, PNG, and WEBP. Every image becomes its own PDF page.
- Any watermark added?
- Never. FormatSwitch adds no watermark, logo, or quality cap to your output — the file you download is only what your browser produced.
- Does it work on mobile?
- Yes. Every tool runs on modern iOS Safari and Android Chrome. Very large files may be slower on mobile because of tighter memory limits.
- Are my images stored anywhere?
- No. Files live only in your browser's memory (JavaScript heap). They disappear when you clear the queue, refresh, or close the tab. There is no server, no database, no log.
- Can I use it offline?
- Yes, after the first visit. FormatSwitch is a Progressive Web App — the tool scripts are cached by your browser, so you can open the same tool later and use it without an internet connection.
