Resize photos to exact pixel dimensions, a percentage, or one-click social media presets — Instagram post 1080×1080, story/Reel 1080×1920, YouTube thumbnail 1280×720, X/Twitter post 1600×900, Facebook cover 820×312, LinkedIn banner 1584×396, WhatsApp DP, Amazon product images and more. Batch-resize up to 30 images with the aspect ratio locked or free, choose crop-to-fill, fit-inside or stretch when the shape doesn't match, and download everything as a ZIP. A 'never enlarge' option avoids blurry upscaled results. Everything runs locally in your browser — no upload, no watermark, no signup — so private and client photos stay on your device. Free.
