Frequently Asked Questions
Will my signature look blurry under 20 KB?
No. Our engine optimizes JPEG quantization matrices specifically to preserve high-contrast pen strokes while discarding invisible metadata.
What should I do if my original file is over 2 MB?
The tool automatically scales down pixel dimensions if needed to safely hit the 20 KB ceiling without quality artifacts.
Are my documents or signatures uploaded to a server?
No. All compression happens completely client-side in your web browser. Your signature never leaves your device.
