Renamio Batch File RenamerPreview, then rename safely
Drop in photos, product images, contracts, course files, or project folders, then use 16+ rules to create clear filenames in bulk. Renamio processes files locally and applies changes only after you review the preview.

Try Online
Try rule chains, result previews, and the undo flow in the browser to see whether Renamio fits the way you organize files.
Fix the four hardest parts of batch renaming
Turn scattered files into consistent names that are easier to deliver, archive, and repeat the next time.
Reuse naming rules
Combine, reorder, and reuse 16+ rules so common naming standards do not have to be rebuilt every time.
Recover from mistakes
Preview old and new names before applying. Rename history gives you undo protection when a batch needs to be rolled back.
Keep files local
Renaming runs on your device, with no need to upload file contents. Use it for client files, contracts, assets, and internal projects.
Built for people who deal with too many files
When filenames affect search, delivery, publishing, or archiving, Renamio turns naming into a repeatable rule-based workflow.
Photo and creative assets
Organize large photo and video batches by date, project, camera angle, or sequence before delivery.

Ecommerce product images
Add SKU, color, angle, and size to image names so listing and handoff work is clearer.
Rename Example

SKU2026001_red_front_1200.jpg
Office and contract archives
Standardize documents by date, vendor, category, and sequence so later search is direct.
Rename Example

2026-CTR-001-vendorA.pdf
Developer project files
Clean exported files, asset packs, and test outputs with regex and reusable rule chains.
