Frequently asked questions
What does the AI image upscaler output?
+
BatchTool exports upscaled JPEG, WebP, or AVIF files. WebP is selected by default, and the output keeps the source aspect ratio.
Are images uploaded for upscaling?
+
No. Processing happens locally in your browser, and selected images stay on your device.
Which output format should I choose?
+
Use WebP for a balanced web default, JPEG for broad compatibility, and AVIF when smaller modern web assets matter most.
