Video compression best practices
Match resolution to playback
Use 1920×1080 for desktop hero videos, 1080×1920 for vertical reels, and 720p for background loops. Smaller resolutions dramatically shrink file size.
Balance CRF and bitrate
Lower CRF values retain crisp detail but produce larger files. Start at 24–26 for marketing assets and adjust until artifacts disappear.
Keep audio clear
Most voiceovers sound clean at 96–128 kbps. Lower bitrates save space, but test on mobile speakers to avoid muffled sound.
Frequently asked questions
What file types can I compress?
This compressor supports MP4, MOV, AVI, MKV, and WebM. Uploads are transcoded with ffmpeg so the compressed video works across browsers and devices.
Will the video lose quality after compression?
Videos are re-encoded using the H.264 codec with optimized CRF values. Lower CRF means higher quality. Use the High Quality preset or adjust manual settings for crystal clear playback.
Can I resize the video for social media?
Yes. Change the scale field (e.g. 1080:-1 for Instagram Reels, 720:-1 for web embeds) to produce pixel-perfect dimensions for your target platform.
Is there a limit on video length?
Compression happens on demand in your session. For best performance, keep uploads under 500 MB.
