EXIF photo dates

Uses DateTimeOriginal from real JPEG camera and phone photos when available.

↩️
Smart fallback

If EXIF is missing, it can use the file’s last modified date so every file stays organized.

🔢
Date-first numbering

Sorts by date before numbering so your renamed files follow a natural timeline.

📁
Monthly folders

In folder mode, organize files into YYYY-MM folders while keeping YYYY-MM-DD filenames.

Build your rename plan

Preview every new filename before saving. Use downloads for safe renamed copies, or folder mode in Chrome/Edge for in-place local organization.

⚠️
Why renamed copies? Browser security prevents a normal webpage from silently renaming files on your computer. This tool safely creates renamed local copies unless you explicitly grant folder access for in-place renaming.

Example filename: 2024-06-15 Vacation 001.jpg. In folder mode, the optional monthly folder would be 2024-06, while the file keeps the full date.

What is EXIF Data & Why Does It Matter?

EXIF (Exchangeable Image File Format) is metadata that digital cameras and smartphones embed directly into JPEG photos. It records the exact date and time a photo was taken (DateTimeOriginal), the camera model, lens settings, focal length, shutter speed, ISO, and sometimes GPS coordinates.

📅
DateTimeOriginal

The moment the shutter was pressed — more accurate than any file date, which changes every time a photo is copied or downloaded.

📷
Camera & Lens

Camera make/model, lens used, focal length — useful for photographers organizing mixed-camera shoots.

📍
GPS Location

Where the photo was taken, if location services were enabled on the device.

⚙️
Shooting Settings

Shutter speed, aperture, ISO, white balance — the technical fingerprint of each shot.

This tool reads the DateTimeOriginal field directly in your browser using low-level file parsing — not a server-side upload. When EXIF isn't available (screenshots, PNGs, downloaded images), it falls back to the file's last modified date so every file gets organized.

Frequently Asked Questions

Answers to common questions about bulk renaming photos, EXIF dates, and browser-based file organization.

Is my data safe? Are my files uploaded when I rename them? ▾

No. All processing happens locally in your browser using the File API. Your photos and files never leave your device. The tool reads EXIF metadata client-side and creates renamed copies locally — whether through browser downloads or the File System Access API for in-place folder renaming.

Can it rename photos by the date they were taken? ▾

Yes. The tool reads EXIF DateTimeOriginal metadata from JPEG photos and uses the real photo-taken date for renaming. Filenames follow a YYYY-MM-DD format like 2024-06-15 Vacation 001.jpg. If EXIF data is missing (common with screenshots, PNGs, and downloads), it automatically falls back to the file's last modified date.

Can I organize photos into monthly folders? ▾

Yes. In folder mode (Chrome and Edge), the tool creates YYYY-MM folder structures and renames files with YYYY-MM-DD patterns simultaneously. For example, a photo taken on June 15, 2024 would be moved into a 2024-06 folder and named 2024-06-15 Vacation 001.jpg.

Does it work on Chromebook, iPad, or tablet? ▾

Yes. Because it runs entirely in the browser, it works on Chromebooks, iPads, Android tablets, and any modern web browser — unlike desktop-only tools like Bulk Rename Utility or Advanced Renamer that require Windows or macOS installation. Download mode works in all browsers; folder mode works best in Chrome and Edge.

What's the difference between download mode and folder mode? ▾

Download mode creates renamed copies you save to your device — originals are never changed. Folder mode (Chrome/Edge only) uses the browser's File System Access API for in-place renaming of files directly on your computer, including creating YYYY-MM subfolder structures. Folder mode is faster for large collections but only works in Chromium-based browsers.

What is EXIF data and why does it matter for photo organization? ▾

EXIF (Exchangeable Image File Format) is metadata embedded in JPEG photos by cameras and phones. It includes the exact date and time a photo was taken (DateTimeOriginal), camera model, lens settings, and GPS location. Using EXIF dates for renaming ensures your files reflect when photos were actually captured, not when they were copied or downloaded — which changes the file system date.

What file types does this bulk file renamer support? ▾

JPEG photos (.jpg, .jpeg) get full EXIF date support with DateTimeOriginal extraction. Other file types — including PNG, HEIC, GIF, WebP, MP4, PDF, and other documents — use the file's last modified date for renaming. All original file extensions are preserved exactly as selected.
