Method, example & boundaries
Batch Image Renamer: from input to a reviewable result
Generate sanitized sequential download names for two to sixteen local images while preserving each file extension. The tool previews the exact name sequence before download, making it useful for product shots, event photos, and content batches that need stable ordering without modifying image pixels.
Worked example: rename a two-file campaign batch
- Example input
- One.JPG and Two.webp; prefix “Summer set”; starting number 7; padding 2 digits.
- Example output
summer-set-07.jpg and summer-set-08.webp
How to interpret it
The prefix is converted to a safe filename stem, numbering follows selection order, and the normalized extension still matches each original file type.
Sanitize, number, and preserve extensions
The browser validates a batch of two to sixteen names, normalizes the requested prefix, checks the starting number and one-to-eight-digit padding, and combines that sequence with each source extension. Renaming prepares download filenames only; image bytes are not re-encoded.
Batch naming boundaries
- Selection order determines numbering, so arrange the batch before generating names.
- Browser download settings may ask for confirmation or handle multiple files separately.
- The operation does not change pixels, metadata, dimensions, or the actual image format.
