Perguntas frequentes
Resizear perde quality?
Diminuir é lossless na percepção - o resizer usa bilinear resampling de alta quality. Aumentar sempre perde nitidez; pra isso, um AI upscaler é melhor tool.
O formato de saída bate com o de entrada?
Por padrão sim. Opcionalmente exporta um PNG redimensionado como JPG ou WebP pra file size menor.
Quais os presets sociais?
Instagram quadrado (1080×1080), Instagram story (1080×1920), YouTube thumbnail (1280×720), Twitter/X post (1600×900), LinkedIn banner (1584×396), Facebook capa (820×312).
Minhas images são enviadas?
Não. O resize roda no seu browser via Canvas API.
