Your file goes into your browser. And that’s where it stays.
Other sites upload your documents to a server and promise to delete them later. Here, the work happens on your own device — so there is nothing to delete.

Questions
Good to know
What is Happy Converter?+
Happy Converter (HappyConverter.com) is a free online file converter with 100 tools for PDFs, images, documents, data and code. You can convert, compress and edit files right in your browser — no sign-up, no installation and no uploads.
Are my files really not uploaded?+
Yes. The tools run as code inside your browser tab, so your PDFs, photos and documents are processed on your own device. There is no server copy and nothing to delete afterwards.
Is everything free?+
All 100 tools are free with no account, no daily limits and no watermarks. A few unobtrusive ads keep the project running.
Does it work on my phone?+
Yes. Every tool works in modern mobile browsers on Android and iPhone, and most keep working offline once the page has loaded.
Is there a file size limit?+
There is no upload limit because nothing is uploaded. Very large files are only limited by your device’s memory.
