Frequently Asked Questions

What is the standard signature size for Pakistani applications?

The most common signature size for Pakistani government forms and applications is 50mm x 20mm (approximately 2 x 0.8 inches). This size is used for passport applications, exam forms, and many official documents. At 300 DPI print quality, this translates to approximately 591 x 236 pixels. Our tool automatically converts to this size when you select the "Pakistan Standard" preset.

How do I create a signature image from a physical signature?

Sign on white paper with black ink, then either scan the signature using a scanner at 300 DPI or photograph it with your smartphone. Ensure good lighting and a flat surface. Once you have the digital image, upload it to our tool, which will help you crop and resize to your required dimensions. The result will be a professional signature image ready for applications.

What file format and size should my signature be?

Most applications require JPG (JPEG) format for signature images, though some accept PNG. File size limits vary but typically range from 10 KB to 100 KB. Our tool will automatically optimize your signature to meet common file size requirements while maintaining quality. We output JPG format at optimal quality, which provides the best balance between quality and file size.

Can I use a digital signature instead of a scanned one?

For most government and official applications, you need a scanned image of your actual handwritten signature, not a digital signature created with a stylus or mouse. The signature should match the one on your official documents. However, for some online forms and informal applications, digitally created signatures may be acceptable. Always check specific requirements for your application.
