FAQ
What does Aspect Ratio Studio do?▼
It helps you change a photo or video to a new aspect ratio (like 9:16, 1:1, or 16:9) so it fits platforms like Shorts, Reels, TikTok, and YouTube.
What’s the difference between crop and fit?▼
Crop fills the frame by cutting off parts of the edges. Fit keeps everything visible but may add padding (letterboxing) to match the target ratio.
Which aspect ratio should I use for Shorts and TikTok?▼
Use 9:16 (vertical). It fits the screen perfectly and performs best for short-form platforms.
Will changing aspect ratio reduce quality?▼
Not necessarily. Quality depends on your export settings. Cropping doesn’t reduce resolution by itself, but heavy scaling can.
Is my media stored?▼
The goal is privacy-first processing. If any server processing is used (for heavy video exports), the page/tool will clearly indicate it.
