Isolate a dark handwritten signature from a light background. This guide explains the workflow in practical terms so you can get a clean result without unnecessary trial and error.
Before you start
Use a sharp, well-lit source with the page as flat and straight as possible. High contrast between text and background gives OCR and scan workflows a better starting point. For Signature Extractor, the goal is simple: isolate a dark handwritten signature from a light background.
How to use Signature Extractor step by step
1. Open the Signature Extractor
Go to the GoodFetch Signature Extractor. The tool page is dedicated to this one workflow, so you can start without navigating a multi-purpose editor.
2. Add the correct input
Select the supported image, PDF, audio file, document, or code image requested by the tool. A clean original usually produces a more reliable result than a heavily compressed copy.
3. Review the available options
Choose settings that match the result you actually need rather than changing every option by default.
4. Run the tool
Select Extract signature and allow the workflow to finish. Avoid closing or refreshing the page while a file is being prepared.
5. Review the result carefully
Proofread names, numbers, dates, punctuation, tables, and small text. Automated extraction can be useful, but it should not replace verification for important information.
6. Save the finished result
Download or copy the result only after the final check. Keep the original file separately when the content matters for work, records, publishing, or future edits.

How to get a better result
Clean capture quality is the biggest factor in document and OCR accuracy. Start with a clean source, use only the settings you need, and compare the final output with the original before publishing or sending it.
File safety and privacy
Use files you are allowed to process and avoid uploading material you do not have permission to use. GoodFetch is designed for task-specific processing rather than permanent file storage. For details, review the Privacy Policy.
