What to know about YouTube Thumbnail Resizer.
Do presets guarantee a platform will accept the image?
No. Presets provide convenient canvas sizes. Platforms can change upload limits and display crops, so check current requirements for your exact placement.
Are my files uploaded for processing?
No. File contents are processed in your browser. The site, codecs and any required models still need to load over the network; local results depend on your device and browser.
