Renaming hundreds of files one by one is one of the most tedious tasks in digital life. We built BulkRenamer to solve that — fast, free, and with complete privacy.
BulkRenamer is a free, browser-based bulk file renaming tool that runs entirely on your device. You drag in your files, set a naming pattern, see an instant preview, and download the renamed copies — all without a single file leaving your computer.
It works with every file type imaginable: photos from your camera, RAW files from a shoot, PDFs from a scanner, spreadsheets, videos, code files, ZIP archives, and everything in between. There is no file size limit, no account required, and no subscription to manage.
The tool was built and is maintained by TrendingVault — a small independent team of web developers and tool builders focused on making genuinely useful free software for everyday people and professionals.
Many file renaming tools either require downloading and installing software, charge a subscription fee, or — most concerning — upload your files to a server to process them. We think that is the wrong approach, especially for people working with sensitive or private files.
BulkRenamer is built on a privacy-first philosophy:
TrendingVault (trendingvault.uk) is an independent publisher of free web tools, browser-based mini games, and utility sites. Our tools are built with a focus on speed, privacy, and accessibility — no bloat, no paywalls, no data harvesting.
BulkRenamer is one of our flagship tools. We continue to actively develop and improve it based on user feedback. If you have a feature request or found a bug, we would love to hear from you.
It takes less than 30 seconds. No signup. No upload. No cost.
