How to Batch Resize Images on Windows
Batch resizing should be repeatable and safe. A professional workflow decides the sizing rule once, previews representative results, verifies output names, and preserves the original folder structure.
Pick a sizing rule
Use Long edge when portrait and landscape photos are mixed. Use Width for a website column, Exact size for a fixed canvas, or Percent for a uniform scale reduction.
Fit keeps the whole image inside a box. Fill crops to cover the box. Contain adds a background canvas. Stretch changes the aspect ratio and should only be used when distortion is intentional.
Protect small images
Enable Never enlarge. Upscaling cannot restore missing detail and often makes small source images look soft. Separating unusually small files into a review queue produces a more consistent batch.
Use Lanczos resampling for high-quality reductions. Add a small amount of sharpening only after testing it on edges, faces, and text.
Preserve folders and create clear names
Add the top-level folder recursively, keep folder structure enabled, and choose a template such as {name}-{width}x{height}. The Output Plan shows the exact path for each file before anything is written.
Save the complete setup as a preset for next week’s batch. The preset includes encoder, resize, edit order, naming, and metadata policy rather than only the most visible controls.
Frequently asked questions
Can portrait and landscape photos be resized together?
Yes. Long-edge and short-edge modes apply the rule according to each image’s orientation.
Will the original folder be changed?
No. Choose a separate output folder; originals are never overwritten.
