Build a rename pattern from blocks: text prefix + EXIF date (YYYY-MM-DD) + sequence number (3-digit) + original extension. Save patterns as presets (“Trip photos”, “Invoices Q3”, “Client files — ACME”) for re-use.

Features
Built around the work people actually need to finish.
Pattern templates
Build a rename pattern from blocks: text prefix + EXIF date (YYYY-MM-DD) + sequence number (3-digit) + original extension. Save patterns as presets (“Trip photos”, “Invoices Q3”, “Client files — ACME”) for re-use.
Cleanup rules
Strip junk from existing names: remove “IMG_” / “DSC_” / “Screenshot” prefixes, collapse multiple spaces, lowercase everything, swap underscores for dashes, trim trailing parenthetical version numbers like “(1)”.
Preview before apply
Side-by-side table: old name → new name for every selected file. Spot collisions (two files would end up with the same name) before they happen. Hit Apply only when the preview looks right.
EXIF + metadata source
Pull date from photo EXIF (when shot, not when imported), screenshot date from filename, PDF metadata title, audio file ID3 tags. The new names actually describe the content.
Undo last batch
One tap reverts the most recent batch rename. Useful when a pattern produced weird results across 80 files — undo, fix the pattern, re-run.
Files app integration
Pick files from any Files location: iCloud Drive, On My iPhone, Dropbox, Google Drive, OneDrive, USB drive over Files. Renamed files stay where they were — no copying, no exfiltration.

Read privacy policy FAQ
Why is there no built-in batch rename on iPhone? +
Apple never shipped it. macOS Finder has had Finder → Rename Items since 2014, but the iOS Files app only renames one file at a time. The omission is a 10-year-old gap. File Renamer fills it on-device, no account, $19.99 lifetime.
Can it rename 500 photos in Photos.app? +
Indirectly. iOS Photos.app stores photos in a system database; third-party apps can’t rename them in-place. Workflow: export the photos to Files first (Share → Save to Files), batch-rename in File Renamer, re-import to Photos. Most people rename for export anyway (sending to a client, uploading to a portal).
Will it scramble files if the pattern is wrong? +
No — the preview pane shows the old→new mapping for every file before you tap Apply. If a pattern produces weird names, you see it. If you apply and immediately regret it, Undo Last Batch reverts the whole operation.
Does it work with files in Dropbox / Google Drive? +
Yes — anything that appears in iOS Files (via the official Dropbox or Google Drive app) is renameable. The rename hits the file in place; Dropbox / Drive sync the new name to the cloud.
Will my files leave the device? +
No. The app reads file metadata (name, size, EXIF date, ID3 tags) and writes new names. File contents never leave the device. Cloud-stored files (Dropbox, Drive) get their NEW NAME synced — same as if you renamed them on a Mac.
What patterns can I build? +
Examples: “{prefix} - {EXIF date YYYY-MM-DD} - {sequence 001}” → “Trip - 2026-05-15 - 001.jpg”. Or “{client} - Invoice {sequence 0001}” → “ACME - Invoice 0001.pdf”. Or strip-only patterns that take “IMG_3847.HEIC” → “img-3847.heic”. Save up to 20 presets in Pro.
