Bulk Image Renamer

Cameras and phones name photos IMG_4821.JPG or DSC09876.ARW, which says nothing about what or when. Renaming hundreds of files by hand is tedious and error-prone. This tool builds new names from a pattern, fills in dates and camera details from each photo’s own data, and hands back the renamed files in one archive.

Building a name pattern

Type the pattern with placeholders. {n} inserts a counter, and {n:3} pads it to three digits, giving 001, 002 and so on, which keeps files sorted correctly. {date} and {time} insert when the photo was taken, and {year}, {month} and {day} let you build your own date layout. {name} keeps the original name, {camera} adds the camera model, and {size} adds the pixel dimensions. Combine them with your own text, for example wedding-{date}-{n:3} or {year}/{month} folders written as {year}-{month}-{name}.

Where the dates come from

Capture dates and camera models are read from the EXIF data inside each photo, the same data that photo apps use. Files without it, such as screenshots and images from messaging apps, fall back to the file date.

Sort order

The counter follows the order you choose: by date taken, the most useful for event and travel photos; by current name; by file date; by file size; or exactly as added. The start value lets you continue a numbering from an earlier batch, for example starting at 251.

Letter case and web-safe names

“As typed” keeps your spelling. “lowercase” avoids mismatches on case-sensitive servers. “web-safe” turns names into lowercase words joined by hyphens, without spaces, accents or special characters, which is ideal for files uploaded to websites, shops and content systems, and helps image search.

What you download

Browsers are not allowed to rename files on your disk. Instead, the tool packs exact copies of the originals, under their new names, into a .zip file. Nothing is re-encoded, so quality and metadata stay identical. A CSV file inside lists every old and new name, handy for records and for undoing the change later.

Preview before downloading

The list shows the new name beside each original, so you can check the pattern before packing. Long batches show the first 300 rows with a count of the rest.

Typical uses

Event photographers numbering a delivery, online sellers creating product-sku-01 style names, families merging photos from several phones into one timeline, archivists applying a naming convention to scans, and developers preparing images with web-safe names.

RAW and other formats

Any file type can be renamed, including camera RAW files, HEIC and videos from the same card; dates are read from formats that contain EXIF.

Privacy

Files are processed in your browser and never uploaded.

Good naming conventions

Start with the date in year-month-day order, so names sort chronologically everywhere. Avoid spaces and special characters, which cause trouble on servers and in some cloud services. Keep names short but descriptive, and use the counter with padding so that photo 10 does not sort before photo 2.
