Free Video Upscaler FAQ
Do I need an account?
No. Open the page and use it.
Is my file uploaded?
No. Files are processed in this browser tab. This tool does not ask for an account or upload your file.
Is there a watermark?
No. PoYo adds nothing to the download.
Why does it pause the first time?
Some tools download an encoder or AI model on the first run. That download contains none of your file, and later runs are usually faster.
