Rename a folder of images at once with a clear pattern — sequential numbers, dates, dimensions, upper/lower/title case — plus find-and-replace, custom start and step values, and drag-to-reorder. Primova bundles the renamed files into a single ZIP, all in your browser.

How to use Bulk Renamer

  1. 1Drop in the images you want to rename (drop or click).
  2. 2Choose a pattern with tokens like {name}, {index}, {date}, {w}x{h}.
  3. 3Tweak numbering, set find-and-replace, and reorder by dragging.
  4. 4Click Build ZIP and download every file renamed in one archive.

Patterns that scale to any batch

Tokens compose like a tiny templating language. Use {name} to keep the original stem, {index} for a zero-padded sequence (automatically sized to the largest number in the batch), {date} for the day, and {w}x{h} to embed dimensions. Need uppercase or Title Case? Add a modifier — {name:upper}, {name:lower}, {name:title} — and {ext:upper} for capitalised extensions.

For exact padding force a width with {index:N} — {index:4} produces 0001, 0002, … even in a small batch. Combine with the Start and Step controls to begin at 100, count by 10, or whatever your workflow demands.

Find & replace, reorder, and check for collisions

Cameras love to add prefixes like IMG_, DSC, or P000. Use Find & Replace to strip them before the pattern runs — flip on regex mode for tricks like collapsing whitespace or matching by suffix. Drag the rows to control which file gets which number, or one-tap Sort A→Z, by size, or by dimensions.

If two files would end up with the same name, Primova flags the duplicates inline and shows a warning banner — adding {index} to your pattern fixes it instantly.

Frequently asked questions

No. Renaming happens entirely in your browser — files are read, repackaged into a ZIP locally with their new names, and never sent to a server.
name, ext, index, date, time, w, h. {name} and {ext} accept :upper/:lower/:title modifiers; {index} accepts an explicit pad width like {index:4}. The live preview reflects every change.
Yes — set Start and Step in the Numbering card. Start at 100 and step by 10 to produce 100, 110, 120, … and the padding auto-fits the largest number.
Yes. Type it into Find and leave Replace empty (or enter a substitute). Toggle regex mode for richer patterns; replacements can use $1 style backrefs.
Drag any row to reorder it on desktop, use the up/down arrows on mobile, or one-tap Sort A→Z, by size, or by dimensions. The pattern’s {index} follows the visible order.
No. The original bytes are packaged into the ZIP under the new filenames — quality and metadata are untouched.
Yes — free with no account, no watermark, and no limit on how many files you rename at once.
