Are my files safe? Do they get uploaded to a server?

No — all conversion happens entirely in your browser using WebAssembly. Your files never leave your device and are never sent to any server. ConverterTo is 100% private by design.

What file formats does ConverterTo support?

We support 40+ formats across five categories: images (JPG, PNG, WebP, HEIC, SVG, AVIF, BMP, GIF, TIFF, ICO), PDFs (merge, split, compress), audio (MP3, WAV, FLAC, OGG, AAC), video (MP4, MOV, AVI, MKV), and utility tools like QR code generators.

Is ConverterTo completely free to use?

Yes. All 42 conversion tools are free to use with no account required. Simply open the tool, drop in your file, and download the result — no signup, no watermarks, no limits.

Why is browser-based conversion better than other tools?

Traditional online converters upload your file to a remote server, exposing your data and requiring a working internet connection. ConverterTo converts files locally in your browser, so it's instant, private, and works even without a stable upload connection.

Is there a file size limit?

There is no server-side file size limit since we never upload your files. In practice, very large files (500 MB+) may be slow depending on your device's memory and CPU. For most everyday files, conversion is near-instant.
