Convert any file,
completely privately
Images, documents, data files and more — all converted in your browser. Nothing is uploaded. Nothing is stored.
Free private file converter — no upload required

Why File Converter is different
Privacy and security
Most online file converters upload your files to their servers — meaning your contracts, financial records and personal photos pass through a third party. File Converter eliminates this risk. All conversion happens in your browser using WebAssembly and the Canvas API. Your file data never travels over the network.
Frequently asked questions
Is File Converter really free?
Yes — completely free with no file size limits, no watermarks and no account required.
Are my files safe?
Yes. Files never leave your device. We cannot see, access or store them — it is architecturally impossible.
What is the maximum file size?
There is no server limit. The practical limit is your browser memory — typically 500MB to 2GB.
Why might Word to PDF shift slightly?
Browser-only Word conversion extracts text and basic formatting. Complex tables or custom fonts may not replicate perfectly.
Can I convert multiple files?
Yes — drop multiple files or select them in the file browser. All convert in sequence.
Does it work on mobile?
Yes — works on iPhone, iPad and Android in modern browsers. Image conversions are fastest.
Do I need to install anything?
No. No app, no extension, no download. Just open the page.
Which browsers are supported?
Chrome, Firefox, Safari, Edge and any modern browser released after 2020.
