Why converting.net is different
Most online converters upload your documents to their servers. converting.net works differently: every conversion runs right in your web browser.
In-browser processing
Powered by WebAssembly: the conversion engines run in your browser, in the memory of your own computer or phone.
Nothing is uploaded
Your files are never sent to our server, so we can't store, read or share them. Only the converter itself is downloaded.
No upload wait
Large files don't have to travel through your internet connection first. The only limit is your device's memory.
Your documents stay with you
Handle contracts, invoices and medical records with peace of mind
Because nothing leaves your device, confidential files stay confidential – no third party ever receives them.

FAQ
Frequently asked questions
How converting.net handles your files.
- Do my files really never leave my device?
- Yes. The conversion engines (ImageMagick, FFmpeg, LibreOffice, Pandoc, pdf.js and others, compiled to WebAssembly) run inside your browser. Your files are read and written locally; our server only delivers the website and the engines.
- Why does the first conversion take longer?
- The engine for a file type is downloaded the first time you need it – for office documents that is LibreOffice, about 77 MB. Your browser keeps it, so later conversions start right away.
- Is there a file size limit?
- There is no upload limit, because nothing is uploaded. How large a file can be depends on your device's memory; very large videos can take a while, since everything runs on your own computer.
- Can I edit password-protected PDFs?
- Yes, after removing the password with "Unlock PDF" – you need to know the password, of course. "Protect PDF" adds a password (AES-256) again.
