Privacidade e limites do navegador
O PicCraft processa PNG resizing no navegador. Os arquivos não são enviados para um servidor, mas imagens muito grandes ainda dependem da memória do dispositivo e dos limites de canvas.
Perguntas frequentes
Are my PNG images uploaded?
Tudo acontece localmente no navegador; nenhum upload é necessário.
Is 640px reasonable for miniaturas?
Yes. It is a practical starting point for small previews and listings, and you can change it before export.
Does resizing keep the aspect ratio?
Yes. The preset starts with an automatic height so the original proportions stay intact.
Can resizing reduce file size?
Usually yes. Fewer pixels often means a smaller export, especially for photos.
Why can very large images fail?
Browsers limit memory and canvas size. Reduce target dimensions or process fewer files if needed.
Do I need to install any software?
No. PicCraft is a web-based tool that runs entirely in your browser without any installation.
