Frequently Asked Questions
Is Signature Extractor completely free? +
Yes! Signature Extractor is 100% free — no account required, no watermarks, and no usage limits. You can process as many signatures as you like.
Is my signature safe? Does it get uploaded? +
Your signature is completely safe. All processing happens locally in your browser using the Canvas API. Your images are never sent to any server — not even ours.
What image formats are supported? +
We support JPG and PNG images up to 10MB. For best results, use a high-contrast image with a white or light-colored background.
How does the background removal work? +
The tool analyzes each pixel's brightness. Pixels brighter than the threshold (default: 128) become transparent, while darker pixels (your signature strokes) are preserved. You can adjust the threshold to fine-tune the result.
Can I use the extracted signature in documents or PDFs? +
Absolutely. The downloaded transparent PNG can be inserted into Word documents, PDFs, Google Docs, PowerPoint slides, or any design tool. The transparent background ensures a clean overlay on any background color.
