Give a folder of photos clean names in the order they were taken
Processed in your browser. Nothing is uploaded. Updated on 25 Oct 2026.Turn IMG_4821.JPG and IMG_20260915_101233.jpg into Goa_01.jpg, Goa_02.jpg in the order the photos were taken. The date is read from the file name where there is one and from the file itself where there is not, so photos from two phones interleave correctly. Add a prefix, pick the numbering width, preview every new name, then rename in place or download them together.
Choose the folder of photos, or press Choose files and pick them.
Order is already Date and Add a number to every file is on; type a Prefix such as Goa_.
Set Start at and Digits, then check names like Goa_01.jpg, Goa_02.jpg in the After column.
Press Rename files on my disk, or Download renamed (zip) to get renamed copies.
The Bulk File Renamer gives a folder of files clean names in one step. It was built for AI video clips - Google Flow names every download with the prompt, a clip number and a timestamp - and it works just as well on phone photos, WhatsApp media, screen recordings and anything else a device names for you.
Files made together are kept together. A batch is every file saved within a few minutes of the one before - ten minutes by default, adjustable - because an AI tool saves one batch across several seconds, not in one instant. Batches follow each other in time, and inside a batch the clip number decides the order, not the second each file happened to be written. So a story made over two days, C01 to C05 on the first and C01 to C07 on the second, comes out numbered C01 to C12.
Only names change. The files themselves are never opened for their content, re-encoded or uploaded, so a 4K or 8K video renames as quickly as a photo. In Chrome and Edge you can pick the folder and the files are renamed where they are; in other browsers the renamed files come back as one zip, stored without compression.
The rest of the article, and all 6 questions about Bulk File Renamer, are on the Bulk File Renamer page.
Drop the files on the page, or pick the folder in Chrome or Edge. Every new name is shown beside the old one: timestamps removed, clips numbered in order, and any prefix, suffix or find-and-replace you add. Press Rename and they change in place, or download them as a zip in other browsers.
Leave "Remove timestamps" on. It finds the stamp in every common form - 14 digits, date and time with separators, WhatsApp dates, epochs - removes it, and tidies the underscores or dashes around it. If two files end up with the same name, the second gets " (2)" so nothing is overwritten.
Each generation in Google Flow starts its clip numbers at C01. Drop all the batches together: they are told apart by the time gap between them, kept in the order they were made, and the clips are numbered straight through, so C01 to C05 and C01 to C07 become C01 to C12.
Every new name is shown before anything changes, and the page keeps a list of old and new names you can download. To undo a folder rename, drop the renamed files back in and use find and replace, or keep the downloaded list to rename them back.
