Preguntas frecuentes
¿Resizear pierde quality?
Achicar es lossless en la percepción - el resizer usa bilinear resampling de alta quality. Agrandar siempre pierde nitidez; para eso, un AI upscaler es mejor tool.
¿El formato de salida matchea el de entrada?
Por default sí. Opcionalmente exportá un PNG resizeado como JPG o WebP para menor file size.
¿Cuáles son los presets sociales?
Instagram cuadrado (1080×1080), Instagram story (1080×1920), YouTube thumbnail (1280×720), Twitter/X post (1600×900), LinkedIn banner (1584×396), Facebook cover (820×312).
¿Se suben mis images?
No. El resizeo corre en tu browser via Canvas API.
