Privacy-first conversion
Convert files without uploading them
Most online converters ask you to upload a file first, which means handing a copy of it to someone else's server. Morphix takes the opposite approach: the conversion engine is downloaded to your browser and the file is processed locally on your own machine.
Why no upload is needed
WebAssembly does the work
Conversion engines such as FFmpeg, pdf-lib and image codecs are compiled to WebAssembly and run inside your browser tab. The CPU doing the work is yours, not a server's.
No file bytes are sent anywhere
Your file is read with the File API into page memory. Nothing is POSTed to an API, written to a bucket, or queued for processing on our side.
Nothing to delete afterwards
Because no copy is ever stored, there is no retention window, no auto-delete timer to trust and no account needed to keep files private.
Works on regular files you already have
Images, audio, video, documents, subtitles, archives and data formats — over 1,300 conversions handled locally in the browser.
How a local conversion works
- 1Open a converter page — no sign-up, no email required.
- 2Choose a file from your device or drag it onto the drop zone.
- 3The engine loads in your browser and converts the file locally.
- 4Download the result straight from the page.

What this does not cover
A few optional extras do involve the network: the AI image tools call a hosted model, and sending a converted file to another device uses an encrypted peer-to-peer connection between the two browsers. Ordinary file conversion on Morphix never sends your file anywhere.
