Privacy, for real

Your files stay yours.

Server-based converters upload your files to their machines and promise to delete them later. FreeConvert never receives them at all — conversion happens inside your browser, on your hardware.

On-device processing

Your browser does the conversion using JavaScript and WebAssembly — the same technology behind browser games and video calls.

Zero storage

There is no storage to delete from. Files are read into memory, converted, and gone when you close the tab.

Nothing to leak

No accounts, no file history, no tracking pixels on your documents. The safest upload is the one that never happens.

Frequently asked questions

Is FreeConvert really free?

Yes — every tool is free and unlimited. Conversion happens on your own hardware, so there are no server bills to pass on to you.

How can files be converted without uploading them?

Modern browsers can read, decode, and re-encode files locally using JavaScript and WebAssembly. Your file is opened in memory, transformed by your own CPU, and handed back as a download. No server is involved at any point.

What formats are supported?

Images (JPG, PNG, WebP, GIF, BMP, AVIF, HEIC), documents (PDF), video (MP4, MOV, WebM, MKV, AVI), audio (MP3, WAV, FLAC, M4A, OGG), and measurement units.

Are there file size limits?

No artificial ones. Because processing is local, the practical limit is your device memory. Phone photos, long PDFs, and multi-hundred-MB videos all work.

Do I need to create an account?

Never. There are no accounts, no email captures, and no watermarks. Open a tool and use it.
