Rename Audio Files Online

"I produce three podcasts and spent way too long manually numbering MP3 episode files. Drop in 50 WAV exports, set the template to PodcastName_S02E{n}_{name}, and they are numbered in seconds. No upload, no privacy issues."

"I was cleaning up my home studio archive of about 400 FLAC and WAV files with inconsistent names from different sessions, and the batch rename with date prefix got them all organized in one go. Handles every audio format."

"As a DJ I manage massive track libraries. The sequential numbering with zero-padding is exactly what I need for playlist ordering. MySet_001.mp3, MySet_002.mp3: clean, sortable, processes 300 MP3s in under a minute."

"I deliver voice-over WAV files to clients and needed a consistent Client_ProjectName_SceneXX naming convention. Used the custom template on 80 files. Client was impressed with how organized the delivery looked."

"Tested it against five other audio file renamers. This is the only one that processes everything locally, confirmed with network monitoring. For a studio handling client recordings that is not a nice-to-have, it is a requirement."

"I record weekly podcast episodes and archive as YYYY-MM-DD_EpisodeTitle.mp3. The date stamp prefix preset does exactly this. Four years of episodes now all consistently named. Would not use anything else."

"Managing a music library of 3,000+ tracks. The find-and-replace regex lets me strip illegal characters, normalize spaces to underscores, and add catalogue numbers. Handles M4A and AAC too, not just MP3."

"Our studio handles sessions for multiple clients. I need ClientName_ProjectCode_Date_TakeXX format on every audio file. The custom template with {n} for take numbers does it perfectly. The zip download keeps file order intact."

"I rename raw interview recordings before editing. Dropped in 30 MP3 files, used the date plus sequence preset, and had them ready to import into Audacity in under a minute. Completely browser-based, no software to install."

"Used it on a huge library of sound effect WAV files, over 600 from different packs with inconsistent names. Regex find-and-replace standardized them all to lowercase_with_underscores in two passes."

"I archive radio broadcasts as FLAC files. The date-prefix preset turned a folder of Broadcast_final_v2_EDITED.flac chaos into 2026-05-12_MorningShow.flac order. Works on batches of any size."

"I produce beats and sell them online. Clean names like Artist_BeatTitle_BPM_Key.mp3 matter for search and my storefront. The custom template covers all of this and the live preview catches mistakes before download."
