Frequently Asked Questions
What is the difference between Drag-to-Crop and Blurred Padding?
Drag-to-crop zooms in to fill the entire 9:16 screen, letting you center the subject. Blurred padding maintains 100% of the horizontal video width while blurring the top and bottom letterbox margins.
Will my exported video have watermarks?
No. All conversions are 100% free and completely watermark-free.
Are large video files uploaded to a remote server?
No. Video rendering and framing execute locally via WebAssembly and Canvas APIs in your browser.
Can I convert vertical 9:16 video back to 16:9 widescreen?
Yes! Select the 16:9 preset and position your vertical video with blurred side padding for YouTube desktop and television display.
