Why use the ToolsFlash images to PDF converter?

Most online converters upload your photos to a remote server, which is slow and risky for private images. ToolsFlash is different: the entire conversion happens inside your browser using the open-source pdf-lib library. Nothing is uploaded, nothing is stored, and there is no watermark, file limit trickery or signup wall. It works on desktop and mobile, and even keeps working offline after the page loads.

Choosing A4 or Letter centers each photo on a standard page with a small margin — ideal for printing or submitting documents. Choosing Fit to image makes every page exactly the size of its image, which is perfect for scanned receipts, screenshots and photo albums.
