BeeConvert uses hardware-accelerated encoding via the WebCodecs API, tapping into your GPU or dedicated media engine. This is the same technology used by native desktop apps — running entirely in your browser with no upload needed.
Yes. Your files never leave your device. BeeConvert processes everything locally in your browser — no server, no cloud upload, no data collection. No one but you can ever see your files.
No. Unlike most online converters that cap uploads at a few hundred MB (or 2 GB even for no-upload tools), BeeConvert has no file size restriction at all. The only limit is the available memory on your device.
Video codecs: H.264, H.265 (HEVC), AV1, VP9. Containers: MP4, MKV, MOV, WebM, AVI, and more. Audio: MP3, AAC, OPUS, WAV, FLAC. Most common formats are supported for both input and output.
Beyond format conversion, BeeConvert supports: Trim (cut by time range), Crop (visual region select with aspect-ratio lock), Rotate (90°/180°/270°) and Flip (horizontal/vertical), Speed change (0.25× to 4×), Volume adjustment, Resolution change, FPS control, and custom quality settings.
Target Size lets you set an exact output file size in MB — for example, compress a video to under 25 MB for WhatsApp, or under 8 MB for Discord. BeeConvert automatically adjusts the bitrate to hit your target. No manual calculation needed.
Yes — in both directions. You can extract audio from a video file (video → audio), or combine an audio file with a video (audio + video → video with sound). Useful for adding background music to a silent video, for example.
Yes. This is a unique feature of BeeConvert. After conversion, your output file keeps all embedded subtitles (SRT, ASS, etc.) and all audio tracks (e.g., multi-language dubs). Most online converters silently strip these out.
Yes. The Merge tool at beeconvert.com/merge.html lets you join multiple video files, audio files, or even a mix of both into a single output file. Just drag and drop your files and click Merge.
Completely free. No subscription, no watermark, no daily usage limit. All features are available without signing up or creating an account.
