Add Padding (Letterbox)

Add padding around images to reach specific dimensions without any scaling or cropping. The original image remains at its exact pixel dimensions, surrounded by padding (in your chosen color or transparent) to fill the target size. This letterboxing/pillarboxing approach preserves 100% of the original content while achieving exact output dimensions.

Specify target dimensions larger than your source image, and the tool adds appropriate padding to each side. Control the background color (any RGB value or transparency for PNG output) and the image position within the padded area—centered by default, or anchored to any edge or corner.

Video producers preparing thumbnails at specific aspect ratios preserve full frame content with letterboxing rather than cropping important action. Slideshow creators normalizing mixed-orientation images to consistent dimensions avoid awkward cropping of portrait images to fit landscape templates. Print designers adding borders or margins around images for framing or matting purposes apply precise padding dimensions. Gallery curators creating exhibition-ready images with consistent outer dimensions maintain individual artwork proportions. Social media managers meeting strict dimension requirements without losing image content choose padding over cropping. Anyone needing exact output dimensions while preserving original image content completely will find padding more appropriate than scaling or cropping solutions.
