About BFOTKit

BFOTKit is a collection of practical browser-based tools for file naming, raster data, screen measurement, sewing-pattern print scale, and PDF and image conversion.

Tools for files and data

The bulk file renamer gives large batches of files consistent names; the ESRI ASCII Grid converter turns raster data into coordinate-based CSV rows. Both process selected files in your browser.

Keep your files on your device

The renamer works with common image, video, document, audio, archive, and other file types while keeping each file’s extension. It does not change your originals. The grid converter reads raster files locally, supports batches and ZIP archives, previews the grid, and can reproject coordinates when you provide the source CRS.

PDF, image, and print tools

BFOTKit also includes PDF to JPG, PDF merging, JPG to PDF, PDF compression, and PDF text conversion to Word. The online ruler helps check screen measurements; the sewing pattern scale checker measures a PDF test square and calculates print scale.

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.
