A small workspace for orderly names
Put filenames in order.
Keep originals intact.
Combine replacement, dates and numbering. Check collisions and export renamed copies as a ZIP plus a mapping table.
01Import files
Paste filenames only
One name per line. List mode exports CSV only.
02Naming rules
Order: replace stem → prefix/suffix → date → number → extension. The last dot marks the extension. Numbering follows selection order.

ZIP uses no compression. File contents are unchanged. Timestamps, permissions and other metadata are not preserved.
Scope and sources
Files stay in your browser. No uploads, original changes or automatic saving. Files are placed at ZIP root without folders. Checks cover Windows reserved names, forbidden characters and a 255-byte UTF-8 limit. Case-insensitive and NFC-equivalent names are treated as collisions. Full path limits depend on your device.
CSV uses UTF-8 BOM and prefixes formula-like values with an apostrophe. ZIP filenames retain their exact text.
