Frequently Asked Questions

Is DaConvert really free?+

Yes, completely free. There are no hidden fees, no premium tiers, no sign-ups required, and no watermarks added to your files. Every tool is available to everyone.

Are my files uploaded to a server?+

No. All file processing happens entirely in your browser using WebAssembly, Canvas API, and other modern web technologies. Your files never leave your device, ensuring complete privacy and security.

Is there a file size limit?+

There is no server-imposed file size limit since everything runs locally. The practical limit depends on your device's available memory (RAM). Most devices handle files up to several hundred megabytes without issues.

Which browsers are supported?+

DaConvert works in all modern browsers including Chrome, Firefox, Safari, and Edge. For the best experience with audio and video conversion, we recommend Chrome or Edge which have the most complete WebAssembly support.

Can I convert multiple files at once?+

Yes. All converter tools support batch conversion of up to 50 files at once. After conversion, you can download all files individually or as a single ZIP archive.

How does browser-based conversion work?+

DaConvert uses advanced web technologies like WebAssembly (Wasm) to run professional-grade software like FFmpeg directly in your browser. This provides the same conversion quality as desktop applications, without requiring installation or file uploads.

What types of files can I convert?+

DaConvert supports images (PNG, JPG, WebP, GIF, BMP, ICO), videos (MP4, MKV, AVI, MOV, WebM), audio (MP3, WAV, FLAC, OGG, AAC), documents (PDF, DOCX, TXT, HTML), spreadsheets (XLSX, CSV, JSON), presentations (PPTX), fonts (TTF, OTF, WOFF, WOFF2), ebooks (EPUB), vector graphics (SVG), and CAD files (DXF).

Do I need to create an account?+

No. DaConvert requires no registration, no email address, and no personal information. Just open the website and start converting files immediately.
