Images to PDF

The JPEG bytes are copied into the PDF as they are — no second generation of loss.
Why these run locally
Every tool on this page processes its input in the browser tab. For this category that matters because the inputs are frequently sensitive: digests of passwords and keys, authentication tokens, spreadsheet exports containing personal data, photographs of identity documents. None of that is transmitted, and the tools keep working if you disconnect from the network after the page loads.
