About BFOTKit

BFOTKit is a collection of practical online tools designed to make common digital tasks easier to finish. The toolkit currently includes utilities for batch file naming and raster data conversion.

Useful tools, made straightforward

The toolkit starts with Mass Rename Media Files, a free browser based utility for giving a large batch of files consistent names. Choose a prefix, starting number, and zero padding, then review and reorder the file sequence before downloading renamed copies together in a ZIP.

Keep your files on your device

The renamer processes selected files in your browser instead of uploading them for renaming. It works with common image, video, document, audio, archive, and other file types because it keeps each file’s extension. The original files remain untouched. The ASCII Grid converter reads raster files locally, supports batches and ZIP archives, previews the grid, and can reproject coordinates when you provide the source CRS.

Built around everyday needs

BFOTKit is intended to bring simple utilities together in one place, with clear controls and useful previews. More tools may be added over time. If you have a suggestion or need help, get in touch.
