Free Bulk File Renamer

No. Bulk Rename runs 100% in your browser — your files are never uploaded to do it. Each file is renamed byte-for-byte (nothing is re-encoded or re-compressed), so it's completely safe for client work, unreleased creative and confidential assets.

Anything you can describe as a pattern. Build names from a token template like {name}_{w}x{h}_v{nn} (image width & height are auto-detected), find & replace text (plain or regex), change case, normalise spaces and symbols, add a prefix or suffix, add a sequential number, and keep or lowercase the extension. Every change shows in a live old → new preview as you type.

It produces the real renamed files. Because a browser can't rename files in place on your disk, you download them back as a single ZIP with the new names applied — renamed byte-for-byte, no quality loss. You can also copy the full old → new rename map as text if you'd rather script it yourself.

Yes. Ad servers are fussy about file names, so there are one-click presets for ad-server-safe names — lowercase, dashes, and stripping unsafe characters — plus automatic {w}x{h} dimension tokens pulled straight from each image. Name a whole banner set to a strict convention in one pass.

Any of them — images, packaged HTML5 ad .zips, PDFs, fonts, documents, anything. Drop a folder of files or a .zip and we'll pull the files out. Need a different edit too? Try Compress Images, Convert Image or Color Picker.

Yes — free to use with no signup, running entirely in your browser. The live rename preview is always free, and a free account downloads the renamed ZIP with no daily limit.

Desktop renamers are one-time purchases, not subscriptions: Batchio Pro is $4.99 (Mac only), A Better Finder Rename 12 is $29.95 single-user (Mac only), and Advanced Renamer is free for personal use but $45 + VAT for commercial use (Windows & Mac) — each licensed per person, per computer. They rename files well, but none of them build campaign names from a convention, and none rewrite the HTML/CSS/JS links inside a renamed HTML5 ad, so a renamed ad package stops working. This runs free in any browser, and a free account downloads the renamed ZIP with no daily limit; PRO ($35/month, under $1 per tool) adds Download all, every size, more share links and saving across all 40+ tools.

Not for the tools themselves. Use and preview every tool with no account. A free account downloads any single result at full size, with no daily limit. PRO adds Download all, every banner size, more share links and saving to your account. A few things keep a small free allowance: QA checks (2 a day with no account, 5 with a free one) and hosted share links (5 a month, 1 a day, live 3 days, each updated up to 2 times). PRO is a flat $35/month ($280/year) for unlimited use of all 40+ tools: no credit packs, no top-ups, no per-use fees. The only pay-per-use extras are optional AI work, paid from the Digi Bot credit wallet with the price shown before you pay: Digi Bot jobs; ✨ Ask AI in the tools and AI drafts in Character Animation, charged for what the AI actually uses (at most 1 credit a request; a new account’s first draft is free); and the AI pictures, voices and video shots of the AI Film Maker (a free account’s free credits make one film; bought credits make as many as they pay for) and of Character Animation (PRO), priced per picture, per line and per second of video. Many comparable tools bill per credit (remove.bg, CloudConvert, AdCreative.ai) — here one flat subscription covers everything. See tools pricing.
