"Batch Processing Setup
Launch PhotoPad and select Batch Edit (or Batch Photo Editor) from the welcome screen or Home tab—this mode lets you load hundreds of images efficiently. Add your photos via Add Files or drag-and-drop a folder; PhotoPad handles large batches well.
Applying Rotation
Go to the Edit tab, click Rotate to add a Rotate layer, then enter your desired angle (e.g., a few degrees like 2.5°) in the properties panel or drag the curved handle on the preview image. This exact rotation applies identically to all loaded batch images; preview on one and confirm it fits the rest. Enable Crop empty areas if needed to trim rotated edges automatically.
Adding Crop
In the Home or Edit tab, click Crop to add a Crop layer—adjust the crop widget by dragging handles for your fixed size/aspect ratio (e.g., preset like 4x6 or custom width/height). Lock the aspect ratio for consistency across all photos, then apply; it uses the same crop bounds for the batch.
Save Changes
Click Apply or Save at the bottom—output to a new folder to preserve originals, choosing formats like JPEG for speed. Process all 700+ in one go; it runs sequentially but efficiently on modern hardware."
