How to use Batch image file renamer

What the tool does, how to run it, and what to expect from the result.

How to batch rename image files

The tool takes up to 200 images, builds one dash-separated lowercase name from the fields you fill in, previews every result, and exports a ZIP of the renamed copies. The bytes are copied through, so nothing is recompressed.

It is a product-image renamer, not a general-purpose pattern engine. If you need a counter with an offset or a regex substitution, this is not it.

  • Add up to 200 image files.
  • Choose a preset, which sets both the field order and the duplicate rule.
  • Fill in the product name (required for a generated name), plus brand, attributes, and year.
  • Scan the preview table and override any individual name.
  • Copy the name list or the full mapping, or download the ZIP.

Tip: a batch renamer should keep the review step obvious

Batch renaming is safer when every final filename stays visible before export. That matters when a catalog team wants consistency without accidentally creating unclear or duplicate names.

The preview-first flow helps keep the batch practical instead of opaque.

Tip: use one product naming logic instead of generic rename macros

Generic file renamers can rename anything, but product image workflows usually need a more specific structure: brand, product, useful attributes, and duplicate-safe handling.

  • Rename multiple product images at once
  • Apply one naming pattern without scripting
  • Keep extensions and duplicate handling intact
  • Copy names, copy mapping, or download the whole batch as ZIP
Tips

Getting a better result out of Batch image file renamer

Specific settings and thresholds, not general advice.

  • The batch cap is 200 files. Anything past that is dropped with a warning rather than silently truncated, so if you are working through a 900 image catalog, plan on five runs.
  • This is not a generic pattern renamer. It has no find and replace, no regex, no counter with a custom start. It builds one product-shaped name from brand, product, attributes, year, and suffix fields. For arbitrary rename rules, a desktop bulk renamer is genuinely the better tool.
  • Names are slugified hard: lowercased, accents folded to ASCII, & turned into the word and, apostrophes dropped, and every run of other characters collapsed to a single dash. Underscores become dashes too, so a naming convention built on underscores will not survive.
  • Duplicate handling depends on the preset. Index mode appends 1, 2, 3, while original-suffix mode appends the last segment of the source filename. The second is more useful when your camera exports already carry meaning like -front and -detail.
  • The ZIP is built with JSZip from the original file bytes, so nothing is recompressed and no quality is lost. The trade-off is that a 200 file batch of large photos produces a ZIP as big as the source folder, held in browser memory while it is assembled.
Limits

What Batch image file renamer does not do

The honest boundary, so you do not lose time finding it yourself.

  • No find and replace, no regex, no numbering offsets. The pattern is fixed by the preset.
  • Maximum 200 files, images only. Non-image files are rejected.
  • It cannot rename files in place on disk. It exports renamed copies in a ZIP.
  • It does not compress, resize, or convert anything.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

How many files can I rename at once?

The tool is built for a practical browser-side batch, so you can rename a sizeable image set in one pass without leaving the page.

Is this better than a generic desktop bulk renamer for product files?

For product image batches, yes. The presets and field structure are tuned for SEO file naming rather than generic numbering or pattern replacement.

Can I copy the final filenames without downloading the ZIP?

Yes. You can copy just the final names or the original-to-new mapping text directly from the tool.

How many files can it handle?

200 per batch. The whole batch is held in the browser tab and zipped there, so a very large batch of high-resolution photos will use a lot of memory. Splitting into runs of 100 is more comfortable on a modest machine.

Can I do a find and replace or use a regex?

No. This renamer builds names from product fields (brand, product, attributes, year, suffix) rather than transforming the existing names. If you need arbitrary rules, a desktop bulk renamer will serve you better. If you need product-shaped names, this is faster.

What happens to characters that are not letters or numbers?

They are collapsed. Spaces, underscores, dots, and punctuation all become a single dash, accents are folded to plain ASCII, & becomes the word and, and apostrophes are removed. Leading and trailing dashes are trimmed and the result is capped at 72 characters.

Do I have to download a ZIP?

No. You can copy only the list of final filenames, or copy the full original-to-new mapping as text, which is useful for a QA sheet or an upload checklist without moving any files.

Are the original files changed?

No. The originals on disk are untouched. The ZIP holds copies with new names and identical bytes.
