# Batch Image Standardization and Compression

Prepare a consistent image set by correcting orientation, removing unwanted margins, applying one size policy, compressing files, and checking representative outputs before delivery.

## Frequently asked questions

### Will every image end up with identical pixel dimensions?

Only if the chosen resize policy fills a fixed box, which may require cropping. A fit or scale policy preserves more of each image but can leave different dimensions or padding, so choose based on the receiving layout.

### How do I choose between whitespace and tolerance trimming?

Use whitespace trimming when the empty margin is clearly blank. Use tolerance trimming when the border is nearly the background color but contains slight variation. Test both on a representative sample before applying the decision to every file.

### Can compression guarantee a target file size?

No. File size depends on pixel dimensions, image detail, format, and quality settings. Set a practical threshold, compare outputs, and record exceptions rather than assuming one setting will hit the same size for all images.

### Why inspect representative samples after the batch finishes?

A batch rule can fail selectively on transparent graphics, tight crops, unusual EXIF metadata, or highly detailed images. Sample acceptance catches those cases before the whole set is published or uploaded.
