Crop first, then fit the selected image
Select a file in the batch list to edit its settings. Drag the crop rectangle over that image, then choose pixel or percentage dimensions and a fit mode. Contain keeps the full selected area with space around it where needed; cover fills the destination and may crop edges; stretch can distort the proportions. Apply settings to all files only when the same crop and dimensions are suitable for the whole batch.
Using Upscale image
A lightweight, non-AI upscaler. Choose 200% or 400% enlargement and review sharpness. Interpolation increases pixels; it cannot reconstruct missing detail.

Frequently asked questions
What is the difference between fit and fill?
Fit keeps the entire image with margins. Fill crops edges to cover the target rectangle. Stretch changes the proportions.
