1, use a scanner. Put the paper document where the seal is located in the scanner for scanning, and use scanning software (such as WPSOffice and hi format matting master) to open the scanned document for editing and saving.

2. Use mobile apps. Use the photo scanning function on the mobile phone, such as "mobile phone scanning king" or "memo", take photos of the seal, then upload it to the computer, use photo processing tools (such as Photoshop) to remove the background, or use special matting software (such as Hi format matting master) to operate.

3. use Word documents. Insert a shape (such as a circle) in a Word document, and then use the WordArt function to input text, adjust the style and position of the text and shape, and make an electronic seal.

4. Use a third-party platform. Use a professional electronic signature platform (such as micro-signature) to upload documents and affix electronic seals. This method is suitable for situations where legal electronic seals are needed.
