Video Tools
Trim, merge, crop, compress and convert videos, create GIFs and add subtitles — all processed locally on your device.
Video files are large, and uploading them to an online converter can take longer than the conversion itself. These tools work with video directly in your browser, using the built-in media engine today and WebCodecs and WebAssembly-based encoders for heavier tasks.
Two tools are ready to use right now. The Frame Extractor saves stills from any clip at full resolution, and Media Info shows duration, resolution, bitrate and aspect ratio. Trimming, compression, conversion and GIF creation are being built on the same local-processing foundation.

Containers vs codecs
A video file has two layers. The container (MP4, WebM, MOV or MKV) is the box that holds the streams and metadata. The codec (H.264, H.265/HEVC, VP9 or AV1) is how the pictures inside are compressed. Two MP4 files can therefore behave very differently: an MP4 with H.264 plays almost everywhere, while one with HEVC may not play in some browsers.
For the widest compatibility, H.264 video with AAC audio in an MP4 container remains the safe default. AV1 and VP9 in WebM give noticeably smaller files at the same quality, and they are well supported in modern browsers.

What determines video file size
File size is essentially bitrate × duration. A 1080p clip at 8 Mbps uses roughly 60 MB per minute, while the same clip at 4 Mbps uses about 30 MB per minute. Resolution, frame rate and motion all affect how much bitrate is needed to look good: fast action and grain need more, while screen recordings and talking heads need far less.
| Resolution | Typical bitrate | Size per minute | Common use |
|---|---|---|---|
| 480p | 1–2.5 Mbps | 8–19 MB | Previews, low bandwidth |
| 720p | 2.5–5 Mbps | 19–38 MB | Social posts, tutorials |
| 1080p | 5–10 Mbps | 38–75 MB | YouTube, presentations |
| 1440p | 10–16 Mbps | 75–120 MB | High-detail gaming footage |
| 4K (2160p) | 20–45 Mbps | 150–340 MB | Archival, large displays |
Frequently asked questions
Common questions about video tools.
Which video formats can I open?
Anything your browser can play. That is typically MP4 (H.264), WebM (VP8, VP9 or AV1), and many MOV files. Support for HEVC/H.265 and some professional codecs varies by browser and operating system.
Is browser-based video processing slower than desktop software?
Inspecting and extracting frames is fast. Full re-encoding in the browser is usually slower than native apps such as HandBrake, especially for long 4K files, but it avoids uploading and downloading gigabytes of data.
Can I extract a still image from a video?
Yes. The Frame Extractor captures the current frame, or one frame every few seconds, as JPG or PNG at the video's native resolution.
How do I check a video's resolution and bitrate?
Open the file in Media Info. It shows the duration, resolution with a label such as 1080p or 4K, the aspect ratio, the orientation and the average bitrate, all without uploading the file.
