As answered by people managing Convertio and Toolpuffin.
Toolpuffin's answer:
Toolpuffin runs its tools inside your browser. Your files and text are processed on your own device and are not uploaded to a server. There is no account or sign-up, and every tool does one job: compress an image, merge PDFs, format JSON, generate a password.
Toolpuffin's answer:
Many free tool sites ask you to upload your files, create an account or wait in a queue. With Toolpuffin you open the page, use the tool and download the result. Because the work happens on your device, it suits files you would rather not send anywhere, such as contracts, payslips and ID copies. You can check this yourself in your browser's developer tools (Network tab).
Toolpuffin's answer:
Anyone who needs a quick, one-off fix without installing software or creating an account: people sending photos or PDFs by email, students and office workers tidying documents, and developers and writers who need small helpers such as a JSON formatter or a word counter.
Toolpuffin's answer:
Toolpuffin is an independent project run by one person. It started from the idea that simple tools should be simple: open the page, do the job, leave. The name comes from a 2019 observation of puffins using sticks as tools. A small bird with the right tool for the job seemed a good fit.
Toolpuffin's answer:
Next.js (static export), React, TypeScript and Tailwind CSS, hosted on Cloudflare Pages. PDF tools use the open-source pdf.js library. The tools run client-side in the browser.

Convertio has earned its reputation by handling just about any file type, not just images. If you sometimes need to switch an HEIC photo to JPG or even convert documents and audio, it’s a strong pick. - Source: dev.to / about 1 year ago

Thanks for sharing! Just to also share my method, I use https://convertio.co for conversions, and then email the books to my [email@kindle.com](mailto:email@kindle.com) account. But I'm glad to hear there's a different solution, thanks! Source: over 3 years ago
