Managing dozens or even hundreds of files manually can be a real headache — especially when each one needs a consistent name. Whether you’re organizing photos, videos, or work documents, doing it one by one wastes both time and patience.
That’s why this online file renamer was built — a simple tool that helps you rename multiple files at once, directly from your smartphone or desktop browser. No need to install anything — everything runs safely inside your browser.
⚡ Rename Hundreds of Files Instantly
Just choose a folder or a group of files, and the tool will automatically detect and list them. You can select which types of files you want to rename — for example:
- 🖼️ Images (JPG, PNG, WebP, etc.)
- 🎬 Videos (MP4, MKV, MOV, and more)
- 🎧 Audio (MP3, WAV, FLAC, etc.)
- 📄 Documents (PDF, DOCX, XLSX)
- 📁 Archives (ZIP, RAR, 7z)
Once selected, you can instantly preview the new names before downloading the renamed files as a ZIP archive.
🧩 Two Rename Modes: Full or Custom
You have complete control over how your files are renamed:
1. Rename All Files
Give your files a single base name (like holiday_photo), and the tool will automatically add numbering — for example:
holiday_photo_001.JPG holiday_photo_002.PNG holiday_photo_003.WebP holiday_photo_004.PNG
2. Find & Replace Mode
If you only want to change part of the filenames, use the Find and Replace feature. For instance, turn every “_old” into “_new”, or remove unnecessary words entirely. You can also add optional numbering for better organization.
🧠 Smart Auto-Numbering and Safe Filtering
The system automatically prevents invalid names and duplicates. It also checks each file extension, making sure only the selected types (like images or documents) are processed. Every filename is sanitized, keeping it compatible across operating systems.
When you hit Preview, you’ll see exactly how each file name will look — including folder structure, file size, and final name. Once confirmed, click Download ZIP, and you’ll get all renamed files neatly packed in a single archive.
🔒 100% Safe and Private
All renaming happens locally in your browser. No files are uploaded to any server, and nothing is stored online. That means your data stays private — perfect for personal photos, confidential work files, or project archives.
📱 Works Everywhere — No App Needed
Whether you’re on a smartphone, tablet, or desktop, this tool works right from your browser. It supports Chrome, Edge, Safari, and Opera — no installation required.
So next time you need to tidy up hundreds of messy filenames, you can do it all in one go — safely, quickly, and without any software.
