Resize and compress your image to exactly the required file size. 100% client-side, zero server uploads.
Black ink on a clean white sheet is standard. It provides the highest contrast for scanner readers.
Crop the image tightly around the signature boundaries before resizing. This removes unnecessary white margins and preserves pixel resolution for the text lines.
Images stay in your browser. Nothing is uploaded to any server.
Official exam portals like SSC and UPSC mandate signature files to be strictly under 20KB (usually between 10KB and 20KB). Our secure tool converts signature images to JPG format and applies high contrast filtering to keep the pen strokes clearly readable.
