Shrink video file size in your browser with quality presets. Free, private, WebM output.
Video Compressor on ezToolFlow shrinks videos in the browser by re-encoding to WebM with quality presets (smallest, balanced, or better quality). Upload a clip, pick a preset, compress, and download a smaller WebM—ideal for quick sharing when full desktop encoders are overkill.
Large phone videos are hard to email or attach to tickets. This compressor draws frames to a canvas and records them with MediaRecorder using WebM (VP9/VP8 when supported). Quality presets scale resolution and target bitrate: low for the smallest file, medium for balance, high for better quality at a larger size. Progress feedback helps you wait through CPU-heavy re-encoding.
Output is WebM, not MP4. That keeps the pipeline workable in modern Chromium browsers without shipping a full FFmpeg build. If a destination requires MP4, convert the WebM elsewhere after download. MediaRecorder support is required—Chrome or Edge is strongly recommended; some browsers may not support the needed WebM codecs.
Re-encoding is CPU-heavy: prefer shorter videos and a single file at a time for a smooth run. Processing stays on your device for this tool path. Use fair-use limits as configured; for archival masters or broadcast deliverables, use professional offline encoders.

Select a clip your browser can play. Shorter sources compress more smoothly than long HD recordings.
Pick smallest file, balanced, or better quality—each trades size versus clarity via scale and bitrate.
Start compression, wait for progress to complete, compare sizes, then download the WebM output.
Reduce file size so a demo or message fits platform limits.
Attach a lighter WebM of the issue without uploading multi-hundred-megabyte originals.
Create a smaller browser-friendly clip before uploading to sites that accept WebM—or convert afterward if needed.
Share work-in-progress footage with teammates without full-resolution masters.
Tip: after you finish, check Related tools at the bottom of this page for the next step in your workflow.
Quick answers about tools, privacy, limits, and pricing.
Yes. Daily limits may apply for guests and free accounts.
Output is WebM (VP8/VP9), which most modern browsers play. Convert to MP4 with another tool if needed.
No. Compression uses Canvas + MediaRecorder on your device.
WebM (VP9/VP8 when the browser supports those MediaRecorder MIME types). Convert to MP4 with another tool if your target platform requires it.
Chrome or Edge on desktop is recommended because of WebM MediaRecorder support. If MediaRecorder is missing or a codec is unsupported, compression may fail with an error.
Re-encoding video is CPU-heavy. Prefer shorter clips, try a lower quality preset, and close other heavy tabs. Large HD files can stress browser memory.
Usually yes when you downscale and lower bitrate, but already-efficient short clips may shrink less. Compare the reported output size before sharing.
This tool is built to re-encode in the browser via canvas and MediaRecorder. You still should not process highly confidential footage on any machine you do not control.
Yes. Video Compressor is free to use on ezToolFlow. Guests and free accounts may have daily limits on some tools; premium tiers can raise or remove those limits. AI tools may also spend credits.
For browser-based tools, processing runs on your device when possible and files are not uploaded for conversion. Optional accounts, usage limits, and AI features are described in our Privacy Policy.
