Useful for breathing room around screenshots, social-media safe areas, or printing margins. Pick the padding thickness in pixels and a background color (white by default — choose transparent to keep the new pixels alpha-zero, which only PNG supports). Output is always PNG so the transparent option works correctly. Conversion runs locally in your browser — files never leave your device.","category":"image","categoryName":"Image","keywords":["image padding","add padding to image","image padding online","image margin tool","add border around image","image whitespace tool","image canvas extender","free image padding","online image padding","add white space to image","image background extender"],"url":"https://toolsly.tools/image-padding","runsOn":"client","multiple":false,"batch":false,"input":{"type":"file","extensions":[".png",".jpg",".jpeg",".webp",".bmp"],"mimeTypes":["image/png","image/jpeg","image/webp","image/bmp"]},"output":{"type":"file","extension":".png","mimeType":"image/png"},"options":[{"type":"number","key":"padding","label":"Padding (px)","defaultValue":40,"min":0,"max":2000,"step":1,"help":"Padding added to all four sides."},{"type":"select","key":"color","label":"Padding color","defaultValue":"white","choices":[{"value":"white","label":"White"},{"value":"black","label":"Black"},{"value":"transparent","label":"Transparent (PNG only)"},{"value":"light-gray","label":"Light gray"}]}],"invocation":{"webUi":"https://toolsly.tools/image-padding","api":null,"notes":"Currently runs client-side in the user's browser.
