Choose a folder, add a list with the current and the new file names, and download renamed copies in a ZIP. Every row is checked for conflicts before anything is created. Free, up to 5,000 rows per batch.
Processed in your browser — your files are not uploaded to our servers.
1. Choose the files
Stays in your browser — not uploaded to our servers.
…or drop files or a folder here
2. Add the list (Excel or CSV)
Choose or drop an .xlsx, .xls or .csv file
Column A: current file name. Column B: new file name. Optional column C: subfolder for the copy. Cells are read as text, so 00123 stays 00123.
3. Check and preview
Windows can fail on paths longer than 260 characters. Enter the folder where you will unzip the copies.

Tap a row for its details.
RowCurrentNewStatus
Add both the files and the list to see the preview.
Some rows are blocked. Fix them in your list and add it again. Nothing is created while any row is blocked.
Off by default. You will be asked to confirm again before the copies are created.
4. Create the renamed copies
Your original files are never changed, moved or overwritten. Files that are not in the list are not copied.
Up to 5,000 rows per batch. For more, split the list into several files.
The ZIP is not compressed, so it is about as large as the selected files, and memory use stays low. Very large ZIPs (over 4 GB) use the ZIP64 format.
Inside the ZIP the copies keep their original modified date. Copies written straight into a folder get today's date.
You need free disk space for the copies, about the same size as the originals.
Questions
Are my files uploaded?
No. Reading the list, checking the names and building the ZIP all happen in your browser. Files are not uploaded to our servers. The only network call is the optional feedback form.
Why are my original files not renamed?
For safety, the tool creates renamed copies and never changes, moves or overwrites the originals. After you have checked the copies, you can delete the originals yourself.
What counts as a conflict?
Two rows with the same new name; names that differ only in upper/lower case (Windows and Mac treat them as the same file); a new name that is already in the folder; characters or names that Windows does not allow; and paths that are too long. Any conflict blocks the run until you fix it. For duplicate new names (including names that differ only in upper/lower case) and new names that are already in the folder, you can instead choose to add numbers and confirm.
How do I make the list?
Choose your folder, then click “Download these names as a list template”. Type the new names in column B in Excel and add the file in step 2. Any .xlsx, .xls or .csv file works (for CSV, UTF-8 is recommended).
Is it free?
Yes. Bulk renaming is free, with no sign-up, up to 5,000 rows per batch.
In what order are the files shown?
In natural order, so file2 comes before file10.

Copyright 2024 The Montserrat.Git Project Authors (https://github.com/JulietaUla/Montserrat.git)
This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is copied below, and is also available with a FAQ at:

-----------------------------------------------------------
SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------
PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.
"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).
"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).
"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.
"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.
PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:
1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.
2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or
in the appropriate machine-readable metadata fields within text or
binary files as long as those fields can be easily viewed by the user.
3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.
4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.
5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.
TERMINATION
This license becomes null and void if any of the above conditions are
not met.
DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
