Questions
Are my videos uploaded?
No. Your files are processed on your device. We never upload them.
What does 720p mean for a tall phone video?
The resolution names the shorter side. A tall 1080 × 1920 phone video at 720p becomes 720 × 1280, keeping its shape.
Can I make a video larger?
Not by resolution. Enlarging adds no detail, only file size, so a video already at or below the chosen resolution keeps its size. A platform size does scale a video to that frame.
What's the difference between Fill and Fit?
Fill covers the whole frame and crops what sticks out, the way Reels and TikTok show a video. Fit shows the whole picture and adds black bars where the shapes differ.
Does resizing make the file smaller?
Usually, because fewer pixels need fewer bits. For a size in MB, use Compress video, which also lowers the bitrate.
How long does it take?
The video is re-encoded with your device's encoder. On a computer, the page shows an estimate under each video. Phone timings are still to be measured; a computer is faster for long or 4K videos.
