Frequently Asked Questions
Everything you need to know about FileFIXR - the most complete online bulk file renaming tool.
How do I rename multiple files at once?
FileFIXR makes it easy to rename multiple files at once. Simply drag and drop your files into the browser, add a prefix (or use the default numbering), and click rename. All processing happens in your browser - no uploads required. You can rename up to 50 files for free, or upgrade to Pro (500 files) or Enterprise (2,000 files) for larger batches.
Is FileFIXR free to use?
Yes! FileFIXR offers a free tier that allows you to rename up to 50 files per batch with a 100MB file size limit. This is perfect for most users. If you need to rename more files or larger files, we offer Pro ($9 one-time) for 500 files and Enterprise ($39 one-time) for 2,000 files. All plans are one-time payments with no recurring fees.
Are my files uploaded to your servers?
No, absolutely not. FileFIXR processes all files entirely in your browser. Your files never leave your device - they are never uploaded, stored, or transmitted to our servers. This ensures complete privacy and security. Everything happens locally on your computer.
What file types does FileFIXR support?
FileFIXR supports all file types - documents, images, videos, audio files, archives, code files, and more. Since we rename files without modifying their content, any file type can be renamed. This includes .pdf, .jpg, .mp4, .zip, .txt, .docx, and any other file format you have.
How many files can I rename at once?
The number of files you can rename depends on your plan. The free tier allows up to 50 files per batch. Pro users can rename up to 500 files, and Enterprise users can rename up to 2,000 files per batch. For batches with 51 or more files, FileFIXR automatically creates a ZIP file for easy download.
Can I rename files without installing software?
Yes! FileFIXR is a web-based tool that works entirely in your browser. There's no software to download or install. Simply visit filefixr.com in any modern web browser (Chrome, Firefox, Safari, Edge) and start renaming files immediately. It works on Windows, Mac, Linux, and even mobile devices.
Is FileFIXR safe and private?
Yes, FileFIXR is completely safe and private. All file processing happens in your browser - files never leave your device. We don't collect, store, or have access to your files. We use industry-standard security practices, and our code is open to inspection. Your privacy is our top priority.
How does bulk file renaming work?
Bulk file renaming with FileFIXR is simple: 1) Select or drag and drop your files into the browser, 2) Choose a prefix or use automatic numbering, 3) Preview the new names, 4) Click rename and download. All processing happens instantly in your browser - no server uploads required. The renamed files are downloaded to your computer.
What's the difference between free and pro plans?
The free plan allows 50 files per batch with 100MB per file. Pro ($9 one-time) increases this to 500 files per batch with 250MB per file. Enterprise ($39 one-time) supports 2,000 files per batch with 1GB per file. All plans offer the same core features - the difference is in the limits. All plans are one-time payments with no subscriptions.
Can I rename files on mobile devices?
Yes, FileFIXR works on mobile devices through your mobile browser. However, file selection on mobile may vary by device and browser. For the best experience, we recommend using a desktop or laptop computer. Mobile browsers have limitations on file handling that may affect the user experience.
Does FileFIXR work offline?
FileFIXR requires an internet connection to load the application initially. However, once loaded, most of the file processing can work offline since it happens in your browser. For the best experience and to ensure you have the latest version, we recommend using FileFIXR with an internet connection.
How do I rename files with a prefix?
To rename files with a prefix in FileFIXR, simply enter your desired prefix in the prefix field (e.g., 'vacation_' or 'project_'). FileFIXR will automatically add the prefix to each filename, followed by a number. For example, 'vacation_1.jpg', 'vacation_2.jpg', etc. You can preview the new names before renaming.
Can I rename files in bulk on Mac/Windows/Linux?
Yes! FileFIXR works on all operating systems - Mac, Windows, and Linux. Since it's a web-based tool, it works in any modern browser regardless of your operating system. There's no need for OS-specific software. Just visit filefixr.com in your browser and start renaming files.
What happens if I rename too many files?
If you try to rename more files than your plan allows, FileFIXR will notify you and prevent the operation. You'll see a message indicating your tier limit and an option to upgrade. For example, free users will be prompted if they try to rename more than 50 files. This ensures fair usage and helps us maintain service quality.
Is there a limit to file size?
Yes, file size limits depend on your plan. Free tier: 100MB per file. Pro: 250MB per file. Enterprise: 1GB per file. These limits ensure the tool works smoothly in your browser. If you need to rename larger files, consider upgrading your plan. The total batch size is also limited by your browser's available memory.
Do I need to create an account to use FileFIXR?
No account is required for the free tier. You can start renaming files immediately without signing up. However, if you want to upgrade to Pro or Enterprise, you'll need to create an account (we use passwordless magic link authentication - no passwords required). Accounts help us manage your tier and provide a better experience.
How fast is FileFIXR?
FileFIXR is extremely fast because all processing happens in your browser. There's no upload time since files never leave your device. Renaming happens instantly - typically in milliseconds for most batches. The only time you'll wait is for the download to complete, which depends on your internet speed and file sizes.
Can I undo file renames?
FileFIXR doesn't modify your original files - it creates renamed copies. Your original files remain untouched. However, if you've already renamed and downloaded files, you'll need to manually rename them back or use FileFIXR again with the original names. We recommend keeping backups of important files before bulk renaming.
What browsers are supported?
FileFIXR works in all modern browsers including Google Chrome, Mozilla Firefox, Safari, Microsoft Edge, and Opera. We recommend using the latest version of your browser for the best experience. Older browsers may not support all features.
