Browser processing
Most FileFiddler tools process selected files directly in your browser. For those tools, FileFiddler does not intentionally upload the original selected file to FileFiddler servers.
Protected reconstruction tools
Some tools use the protected FileFiddler processing service at api.filefiddler.com for reconstruction logic while keeping the original file local.
JPG → Excel: image reading and OCR run in your browser. The protected service receives OCR text boxes and lightweight line geometry needed to reconstruct the spreadsheet. The original image is not sent by this workflow.
PDF → Excel: PDF text extraction runs in your browser. The protected service receives extracted text and page coordinates used to infer rows and columns. The original PDF is not sent by this workflow.
Split PDF by Category: page text is extracted locally and sent to the protected service to detect and assign category labels. The actual PDF splitting and downloadable output are produced locally in your browser.
