How Any File Converter works

Our free online converter lets you transform any kind of file — PDF documents, images, videos, or audio — in seconds, right from your browser with no software to install. The entire process is secure, fast, and compatible with all devices.

  1. Upload the files you want to convert
    Drag your files into the central box or click the “Choose files” button. You can upload documents, images, videos, or audio in any format.
  2. Files are automatically added to the queue
    Every uploaded file appears in the list with a selectable output format (for example from PDF to Word DOCX or from MP4 to WEBM). You can adjust quality and conversion type before starting the process.
  3. Start the online conversion
    Click “Convert” to begin: you’ll see a real-time progress bar and, when it’s done, you’ll get a notification with a button to immediately download the converted file. All conversions happen in the browser — no files are sent to our servers — for maximum privacy and security.

Any File Converter supports over 100 different formats and automatically optimizes file quality based on content type. It’s the ideal solution if you need an online file converter that’s fast, free, and secure.

Frequently asked questions about Any File Converter

Unsure how Any File Converter’s free online file converter works? Here are answers to the most common questions about speed, supported formats, security, and privacy.

Do conversions really happen locally?

Yes, all conversions are processed directly in your browser thanks to WebAssembly technology. Files are never uploaded to our servers: they always remain on your device, ensuring maximum confidentiality and compliance with privacy regulations.

For very large files or complex formats, the system may suggest an optional cloud-based fallback to complete the conversion without interruption, but it’s always up to you.

Which file formats can I convert with Any File Converter?

Any File Converter supports hundreds of different extensions across video, audio, images, and documents.

Video: MP4, WEBM, MOV, MKV, AVI, GIF. Audio: MP3, WAV, AAC, OGG, FLAC, M4A. Images: JPG, PNG, WEBP, HEIC, HEIF. Documents: PDF, with the option to convert PDF to Word (DOCX) or create a PDF from images.

The online converter is continually updated to ensure compatibility with the most widely used formats on Windows, macOS, Android, and iOS devices.

How fast is file conversion?

Conversion speed depends on your device performance and the selected quality level.

The “Fast” preset uses optimized settings for minimal processing time, ideal for light files or bulk conversions. The “High quality” preset favors visual and audio fidelity, perfect for professional projects or complex video files.

On average, converting a PDF document or an image takes under 5 seconds, while videos convert in near real time thanks to the FFmpeg engine running in the browser.

How is my privacy protected?

Any File Converter is designed to keep you safe and private:

  • No registration or login required.
  • No mandatory file uploads: everything happens locally.
  • No tracking or storage of processed content.

This approach lets you convert sensitive documents, such as contracts or certificates, with full peace of mind. Our service follows privacy by design principles and does not store or analyze uploaded files.

Is the file converter free?

Yes, Any File Converter is completely free and accessible from any browser. There are no hidden subscriptions, no daily limits, and no watermarks on downloaded files.

You can convert as many files as you want — even simultaneously — directly online. The service is supported by internal optimizations that ensure sustainability and high performance at no cost to you.
