Bulk Rename Files Batch rename files or images with numbering, find and replace, date patterns, and cleaner filenames when you need a faster way to organize uploads. ZIP Compressor Create a ZIP file from multiple files or folders in your browser with visible file lists, compression levels, progress feedback, and a clean download flow.

Bulk Rename Studio is the browser-side version of a naming rules workbench. Instead of typing a pattern and hoping it works, you can upload a batch of files, build the rename pattern with tokens, and see every new filename update live before you download anything.

The token system is designed for practical batch work. Keep the original filename, preserve the extension, add a zero-padded counter, stamp today's date, or switch the original stem into upper or lower case. This makes it useful for gallery assets, client handoff packs, scanned admin files, product images, and any folder where consistency matters more than fancy automation.

A live preview matters because naming errors are expensive in batches. One bad pattern can produce duplicate filenames or meaningless names across dozens of files. The preview table shows the original name and the generated result for every file so you can catch problems before the ZIP is built.

The original files are never modified. The tool creates renamed copies and packages them into one ZIP download, which keeps the workflow safe and reversible.

What to Expect

Preview token-based filename changes live, catch duplicate outputs early, and download a ZIP of renamed file copies without touching the originals.

Best for

  • Preparing product images, ad assets, or gallery files with cleaner naming rules.
  • Adding date and counter patterns to recurring client or team deliverables.
  • Checking for duplicate output names before a batch rename leaves your device.
  • Creating one ZIP of renamed copies without touching the originals.

Not ideal for

  • Renaming files in place on your disk or changing folder structures directly.
  • Complex conditional rules based on file contents, metadata, or nested directories.
  • Very large archive-management jobs where you need desktop file system automation.

What this tool keeps

  • Your original files exactly as uploaded.
  • Correct file extensions when you include the extension token.
  • A live one-to-one preview between current and new names.

What may need cleanup

  • Overly long filenames that may still be awkward on older systems or shared drives.
  • Manual pattern tweaks when the first token mix creates duplicate names.
  • Spacing or punctuation cleanup if the original filenames were inconsistent.

Common errors

  • Leaving out `{{ext}}` and expecting extensions to be appended automatically inside the visible filename pattern.
  • Using a pattern that resolves multiple files to the same output name.
  • Expecting the tool to overwrite files in place instead of packaging renamed copies in a ZIP.

Example use cases

  • Renaming 80 product images to a date-plus-counter pattern before marketplace upload.
  • Standardizing client handoff filenames across mixed PDFs, JPGs, and docs.
  • Creating lower-case SEO-friendly names before moving assets into a CMS.
  • Batch-numbering scanned forms for easier review and archive sorting.

Sample input

Pattern: product-{{date}}-{{counter}}.{{ext}} with start 1 and step 1, applied to files like IMG_4401.JPG, IMG_4402.JPG, and IMG_4403.JPG.

Sample output

A preview and ZIP download where the files become product-2026-04-19-001.JPG, product-2026-04-19-002.JPG, and product-2026-04-19-003.JPG, with duplicates flagged before download if the pattern collides.

Who this is for

  • Content teams, ecommerce managers, and designers cleaning up filenames before upload.
  • Operations or admin staff standardizing batches of exported files.
  • Anyone who wants predictable rename rules without touching the originals.

Why token-based renaming is useful

Tokens let one pattern adapt across mixed filenames without scripting. A rule like client-{{date}}-{{counter}}.{{ext}} works across JPG, PDF, DOCX, and CSV files while still preserving the correct extension automatically.

What the duplicate warning protects against

Duplicate outputs are the fastest way to break a rename batch, because two different files may try to land on the same final name. The preview flags those collisions immediately so you can adjust the pattern before download.
