Bulk File Rename

Bulk file rename is the fastest way to clean up hundreds or thousands of badly named files at once — camera dumps like IMG_9042.CR2, client exports like final_FINAL (2).pdf, or code files scattered across cases and separators. This bulk file rename tool works right in your browser: drop files into the workbench above, type one name, check the live preview, and download everything as a ZIP. No account is required — files are processed locally in your browser. File contents are not uploaded to our servers. What bulk file rename does A bulk file rename answers one question at scale: what should these files be called? You have a folder of photos, invoices, or assets with inconsistent names, and you need clean, uniform, searchable filenames. Doing it by hand is possible, but one typo can wreck hundreds of files with no undo. This one does it mechanically. You give it files; it applies your pattern — numbering, dates, case fixes — and shows every result side by side before anything is downloaded. That makes it a practical bulk file rename utility for photographers, video editors, accountants, and anyone stuck with messy folders. Rename photos, documents, and everyday files — without doing them one by one A camera card full of IMG_9042.CR2, a downloads folder of final_FINAL (2).pdf, hundreds of screenshots or receipts — renaming them one by one takes hours and invites typos. Type one name like Photo 001 and numbering continues automatically — 002, 003, and so on. Check every result in the live preview, then download everything as a ZIP. No install, no account. Files are processed locally in your browser. Rename photos, PDFs, and documents on any computer Phone exports named Screenshot 2026-09-12 at 18.22.40.png, client files named final_FINAL (2).pdf — the same one-name workflow cleans them up on Windows, macOS, Linux, and Android phones, even on Chromebooks and school PCs where you can't install anything. Try a date-stamped name such as 2026-09-14_001 in the tool above, then tweak the pattern live. It works just as well for client work and personal photo libraries. Add numbers, dates, and clean up messy names Messy names usually need three things: sequential numbers that sort correctly (001, 002, 003), the same words added to many files at once, and small cleanups like removing (1) or copy from dozens of names. Do all three in one pass: type a pattern, use find & replace for the messy bits, and check the live original → new preview until every row looks right. Duplicate names are flagged before you download, so nothing gets overwritten. See the features for the full list. How to get a cleaner rename Pad your numbers. Photo 001 sorts correctly past 100; Photo 1 does not. One pattern per batch. A heading and body text in the same run pull the results in two directions. Make names consistent first. Lowercase before numbering keeps everything uniform. Keep original extensions. Leave File format on Keep Original Format unless you mean to convert. Clear collisions before download. Add numbering or a {date} token until the warning clears. What to check before you rename a batch Judge any renaming method on five things: live preview before commit, warnings before duplicate names, zero-padded numbering, consistent letter case, and privacy (file contents are not uploaded to our servers). This free tool checks all five and works in any modern browser on Windows, macOS, and Linux
