Resize Signature for Online Forms
Resize a signature to exact pixels and KB — for example 140×60px under 20KB — for exam and government forms. Free and private in your browser.
Upload your signature photo or scan
JPG or PNG — sign on white paper for best results
Choose ImageForms that reject “wrong size” signatures
Exam and government portals often demand a signature at a precise size such as 140×60 pixels and under 20KB as JPG. A phone photo of your signature fails both rules at once. This resizer applies the pixel box and the KB cap in one pass.
Use built-in presets for common Indian exam forms, or enter the width, height and max KB printed on your own instructions.
JPG on white vs transparent PNG
Most portals want a white-background JPG. Choose that when the form says JPEG only. Transparent PNG is better when you place a signature onto a document yourself.
Processing is local. Your signature image is never uploaded.
