Workflow Notes

Best for

Product, catalog, and marketplace image sets that need a strict shared naming scheme across all items and variants.
Photo collections prepared for batch delivery where team members need a predictable list of filenames before final upload.
Video thumbnails, gallery batches, or social grids that must stay sorted by shot sequence or editorial order while preserving the original extension.
Workflows that require a CSV handoff to project management or DAM systems for final QC checks before publication.

Check before using it

Confirm required final naming rules with the destination system first, including case, separator, and index position expectations.
Choose file names or a sheet format you need to match, then set start index and padding so numbers line up with your destination convention.
Check that every selected item is the image type you intend and that the browser list order matches your expected shot order before previewing.
Keep an untouched copy of source files outside the renaming output so you can rerun with corrected settings quickly.

Review the output

After preview, verify that generated names use the intended sequence and that no gaps, duplicates, or skipped numbers exist from start index through last row.
Open the CSV copy and confirm delimiter usage, exact spelling of base names, and that every original filename has one and only one mapped renamed value.
Spot check at least two adjacent files against your target structure, for example item1 with item2, to catch off-by-one errors in index and ordering.
Validate file extensions: the tool keeps each source extension while renaming only the stem, so output must remain readable by your downstream tools or upload script.

Limits to keep in mind

The tool does not inspect or preserve advanced file metadata, checksums, or duplicate detection rules. It only generates names, preview rows, and downloadable renamed blobs.
Ordering is based on the browser file selection order, so visual order and selection order can differ if files are dragged from complex folders.
There is no batch zip export, path control, or nested folder output; each renamed result is downloaded individually with a single-click link.
No account, cloud sync, or hidden AI service is used, so all processing is limited to what is currently loaded in this page and this browser tab.

Handoff

Pass the CSV and renamed outputs to EXIF Metadata Remover when you need privacy-safe files before sharing publicly.
Use Image Compressor after renaming if publishing size budgets or page performance targets require smaller file weights.
Follow with Image Resizer when exact pixel standards are required for ecommerce cards, marketplaces, or social platforms.
If names must match catalog data, import the copied CSV into your CMS or asset tracker before final delivery.

How to Use

Select all source images at once from your device. The tool reads only client-side inputs and does not create or upload anything to a server.
Set the base name, starting index, number padding, and case style. Use kebab-case for URL friendly folders, snake_case for scripts and spreadsheets, or plain when no separators
Click Preview Names. The page immediately generates a table with original name, proposed new name, file size, and a per-file download action.
Review the mapping table and order. If any item is wrong, adjust the fields and click Preview Names again. This updates rows instantly without reloading the page.
Copy the CSV map for handoff or click each Download link to save renamed files locally with the visible target names.

FAQ

Is Batch Image Renamer free?

Yes. It runs in the browser and does not require an account.

What does it do?

Rename image files locally in the browser with custom naming patterns, sequence settings, local preview, CSV mapping, and direct renamed downloads.

What should I use next?

Usually EXIF Metadata Remover is the next step when you want to create a local, privacy-clean copy of selected images before sharing or upload by removing embedded metadata while keeping the visual content intact.

Does this tool require an account or login?

No. It is a free browser tool and runs in your current session without an account.

Are my images uploaded to your servers?

No. Files are handled only in your browser session, and only the preview table and renamed links are produced locally.

Can I undo renamed files after download?

Downloads are created with the target names, so keep originals in a separate folder and use that folder to retry if you need a different pattern.

What should I check if uploaded files fail because of names?

Use Preview Names first, verify start index and padding, then copy the CSV and compare required ordering and numbering against your destination requirements.
