Frequently asked questions
Is 30KB enough for a clear signature?
Yes, 30KB is more than enough for a very high-quality signature, provided you crop out the extra white paper around it before compressing.
Is this tool safe for official documents?
Yes. We use HTML5 Canvas to process the image directly inside your web browser. The file is never sent to our servers.
What if the portal says max 20KB?
If the portal specifies 20KB, please use our 20KB signature compressor instead.
