Morphr vs. online file converters
Most popular file converters work the same way: you upload your file to their servers, they convert it there, and you download the result, trusting them to delete it afterwards. Morphr is built differently. The conversion runs on your own device, in your browser, so there is nothing to upload, store, or delete.

Why “deleted after 24 hours” isn’t the same as private
A deletion policy is a promise about what happens after your file has already left your hands: it travels to a server you don’t control, waits in a queue, gets processed, and is stored until a cleanup job removes it. For many files that’s fine. For contracts, medical records, ID scans or private photos, it’s a risk you don’t need to take. A converter that never receives your file has nothing to delete, leak, or get breached.
Don’t take our word for it
Open your browser’s developer tools, switch to the Network tab, and convert a file with Morphr. You’ll see no upload. No request carries your file anywhere. Server-based converters can’t offer that check: their conversion only works because your file is sent to them.
When a server-based converter makes sense
In fairness: server-side converters can handle a few jobs a browser can’t, like multi-gigabyte videos or exotic formats that need licensed codecs. For everything else (images, documents, spreadsheets, data, common audio and video) your own device is faster, has no limits, and is private by default.
