FAST ANSWERS
Before you drop a file.
Is FastTool free?
The public tools featured here are free to try and do not require an account. A page states any file, size or browser limit before export.
Are my files uploaded?
Featured local workflows use browser file APIs and do not include a file-upload path. Ordinary page assets and consent-controlled analytics may still make network requests; every tool states its exact boundary.
Can I compress an image to 100 KB?
Yes. Open the 100 KB image compressor, choose an image and check the result. It searches for a file below your limit and shows the actual size. Very small limits can require lower quality or fewer pixels.
Does PDF to Excel work on scanned documents?
No. The PDF table extractor reads selectable text, not photographs of pages. You can review detected rows before downloading XLSX or CSV.
