Quick Answer
Plainscan's batch file renamer lets you rename multiple files at once — online, free — by uploading your files, setting renaming rules, and downloading the results. A free account is required; no credit card needed. Files are processed securely and deleted within 24 hours.
What Is Plainscan's Batch File Renamer?
Plainscan's Batch File Renamer is a free, browser-based tool that lets you rename dozens, hundreds, or even thousands of files simultaneously using customizable renaming rules — all without downloading or installing any software.
Whether you need to add a consistent prefix to every file, replace specific text in filenames, number files sequentially, change letter case, or build entirely new naming structures, this tool handles it in seconds. Unlike standalone desktop software like Bulk Rename Utility or Advanced Renamer, Plainscan's batch renamer requires nothing beyond a web browser and a free account. It works equally well on Windows, macOS, Linux, and mobile devices.
And because it is part of Plainscan's complete document productivity platform, you can rename your files and then immediately use Plainscan's other tools — compress a PDF, run OCR on a scanned document, remove an image background — all in one workspace without switching apps.
How It Works
(1) Upload your files (any type up to 50 MB free). (2) Define your renaming rules: prefix, suffix, numbering, or find-replace. (3) Preview the changes and click Rename to download your organized files as a ZIP or individual files.
Why Use Plainscan?
Proper file naming is critical for SEO, project management, and digital archiving. Plainscan eliminates the repetitive work of organizing large media libraries, project assets, or document backups.
