Resumen

Instagram wants a square. LinkedIn wants 16:9. TikTok wants 9:16. Your photo was shot at whatever ratio your camera felt like. Cropping removes parts of the frame you might care about. Padding does not: it just adds a coloured background around the image until it hits the aspect ratio you need.

This tool extends one image per request to a target aspect ratio without touching the original pixels. The padded area is filled with a colour of your choice: a solid background, a brand accent, or full transparency for PNG, WebP, or AVIF outputs. You pick the ratio (1:1, 16:9, 9:16, or a custom ratio like 4:5), the colour, and the alignment (centre, top, left, and so on).

Padding runs entirely in your browser. Your browser decodes, composites, and re-encodes the image on your own device, then hands you a download. Nothing is uploaded, nothing is saved, nothing is indexed or trained on, because we never see the pixels.
