Frequently Asked Questions
Is this video resizer free?
Yes! The FreeTools Guru video resizer is completely free to use with no signup required.
Can I resize videos for Instagram or YouTube?
Yes. Use Square 1:1 or Portrait 4:5 for Instagram feeds, Vertical 9:16 for Reels and Stories, and 1080p or 720p for YouTube.
What is the difference between contain and cover?
Contain keeps the entire video and adds black padding to match the target aspect ratio. Cover fills the target size and crops the edges if needed.
What video formats are supported?
You can upload MP4, MOV, MKV, WebM, AVI, and M4V video files. Output is always MP4 for compatibility.
Why is my MP3 file smaller than the MP4?
MP3 stores only the audio stream, while MP4 also contains the video, so the extracted audio is much smaller than the full video.
