4 Ways to Split Video for Every Need

Pick the best way to split video for your workflow — manual precision, bulk automation, or anything in between.

Manual Split (Timestamps + Preview)

Manual Split (Timestamps + Preview)

Click anywhere on the waveform / thumbnail timeline to split video precisely. Drag markers to reposition, or type exact timecodes for frame-level accuracy. Use the preview player to verify each segment before exporting.

Equal Parts Split

Equal Parts Split

Choose the total number of segments (e.g., 4 equal parts) to split video into uniform chapters. Ideal for breaking lecture recordings or long-form content into equal-length clips.

Split by Duration

Split by Duration

Set a segment length (e.g., 30 seconds) to split video by fixed intervals. The splitter chunks the entire video into clips of that duration — the final clip may be shorter if there's leftover footage.

Split by Size

Split by Size

Split video by file size — specify a target MB per clip. Perfect for upload limits on social platforms or messaging apps.

  • •Fast Mode: Estimates size from bitrate and adjusts timestamps to fit.
  • •Advanced Mode: Re-encodes clips to hit exact target sizes (longer process).

Why Split Video Locally Instead of Cloud

When you split video with cloud tools, you must upload, wait for remote processing, and re-download. Our local-first approach skips all of that.

Security: Your footage never leaves your machine — essential for confidential or personal videos.
Speed: No upload queue means you start splitting the instant the file loads.
No Limits: Process files of any length or resolution without hitting server quotas.

Fast Mode = Stream Copy (No Re-encoding)

Enable Fast Mode to split video instantly by copying the original streams. The only trade-off is that cuts snap to the nearest keyframe (typically within a second), but you save minutes on large files.

Use Fast Mode for quick splits; disable it when you need frame-perfect timing or want to convert formats.

Advanced Options (Format + Quality Control)

When Fast Mode is off, you can choose a different output container (MP4, WebM, MOV, MKV, AVI…) and set quality to High, Medium, or Low. This re-encodes clips, which takes longer but gives you format flexibility and precise cuts.

Zero-Upload Privacy

Zero-Upload Privacy

When you split video here, all processing uses WebAssembly-compiled FFmpeg in your browser tab. No data leaves your device — there's no tracking, no cloud account, and no server logs. Close the tab and everything is gone.

Works on Desktop & Mobile (Best on Chrome/Edge)

We recommend Chromium-based browsers (Chrome, Edge, Brave) for the smoothest experience. Firefox and Safari work for smaller files but may be slower. On mobile, Chrome on Android handles most videos; iOS Safari has limited WASM performance.

Frequently Asked Questions

01Is it safe to split video online?+
Yes! When you split video with our tool, everything processes locally in your browser. Your video files are never uploaded to any server, making it completely private and secure.
02What video formats can I split?+
You can split MP4, WebM, MOV, MKV, AVI, FLV, 3GP, MPG, WMV, and many other video formats. The tool automatically detects the format and processes it accordingly.
03How do I split video into equal parts?+
Select 'Equal Parts' mode, choose the number of segments you want, and click Split Video. The tool will split video into equal-length clips automatically.
04Can I split video files of any size?+
Yes! Since processing happens in your browser, there's no file size limit imposed by servers. You can split video of any size — your computer's memory is the only constraint. For very large files, consider using Fast Mode for quicker processing.
05What's the difference between Fast Mode and normal mode?+
Fast Mode lets you split video instantly using stream copy without re-encoding, but cuts may snap to the nearest keyframe. Normal mode re-encodes for frame-accurate cuts and lets you change the output format and quality.
06Are AV1 encoded videos supported?+
Yes! AV1 videos are supported in Fast Mode, which uses stream copy to split without re-encoding. Note that cuts will snap to the nearest keyframe. Re-encoding AV1 is not supported in browser.
07Why do my clips start a second or two off from where I placed the split?+
In Fast Mode the tool cuts at keyframes (I-frames) rather than arbitrary frames. Keyframes are typically 1–2 seconds apart. Disable Fast Mode and re-encode for frame-exact cuts.
08Can I change the output format of my clips?+
Yes — disable Fast Mode and select your preferred container (MP4, WebM, MOV, MKV, AVI, etc.) plus quality level. The tool will re-encode each clip accordingly.
09How long does it take to split video?+
Fast Mode is nearly instant for any file size. Re-encoding depends on your CPU and video resolution; a 5-minute 1080p clip typically takes 30–90 seconds on a modern laptop.
10Does this work on mobile devices?+
Mostly. Chrome on Android handles moderate-size videos well. iOS Safari is slower due to limited WASM performance. For large 4K files, a desktop browser is recommended.
11Can I split a video without losing quality?+
Yes. Enable Fast Mode and the tool copies the original video and audio streams without re-encoding, so quality is bit-for-bit identical to the source. The only caveat is that cuts snap to the nearest keyframe, which may be up to a second or two from your chosen split point.
12How do I split a video for Instagram, TikTok, or YouTube Shorts?+
Use the 'By Duration' mode and set the segment length to match the platform's limit — 90 seconds for Instagram Reels, 10 minutes for TikTok, or 60 seconds for YouTube Shorts. You can also use Free Split mode to place cut points at exact moments for cleaner transitions between clips.
13What happens to the audio when I split a video?+
Audio is always preserved. Each output clip contains the corresponding audio segment synced to the video. In Fast Mode the original audio codec is copied as-is; in normal mode the audio is re-encoded alongside the video to match your chosen output format.
14Can I split videos that have burned-in or soft subtitles?+
Burned-in (hardcoded) subtitles are part of the video frames, so they carry over automatically to every clip. Soft subtitle tracks (SRT/ASS embedded in MKV or MP4) are preserved in Fast Mode since the streams are copied directly. In re-encode mode, subtitle tracks may be dropped depending on the output container.
15How do I split 4K or high-resolution videos?+
Use Fast Mode for the best experience with 4K files. Because it copies streams instead of re-encoding, even large 4K videos split in seconds regardless of resolution. If you need to re-encode, expect longer processing times — a modern laptop can take several minutes per minute of 4K footage.
16What is a keyframe and why does it matter for splitting?+
A keyframe (or I-frame) is a full image frame that doesn't depend on other frames for decoding. Video codecs like H.264 only insert keyframes every 1–4 seconds. In Fast Mode, cuts must land on keyframes because the tool copies compressed data directly — cutting mid-group would produce a corrupt clip.
17Can I merge or rejoin clips after splitting them?+
This tool is designed for splitting, not merging. However, you can use our Video Converter tool to concatenate clips back together if they share the same codec and resolution. For more complex joins, a desktop editor like Shotcut or DaVinci Resolve is recommended.
18How do I split a screen recording efficiently?+
Screen recordings are typically low-motion with long keyframe intervals. Fast Mode works well and finishes almost instantly. If your recording uses a variable frame rate (common with screen capture software), switching to re-encode mode and exporting as MP4 ensures consistent playback timing in each clip.
19Can I split videos that have multiple audio tracks?+
In Fast Mode, all audio tracks are preserved in each output clip because the streams are copied as-is. In re-encode mode, only the default (first) audio track is included. If you need to keep multiple tracks, stick with Fast Mode and use an MKV or MP4 container.
20Does splitting preserve the original video metadata?+
Fast Mode preserves most metadata — including creation date, rotation flags, and color space info — because the streams are copied without modification. Re-encode mode may strip some metadata depending on the output format. Critical metadata like aspect ratio and frame rate is always maintained in both modes.
