Questions fréquentes
Are my JPG images uploaded?
Tout se passe localement dans le navigateur; aucun envoi n’est nécessaire.
Is 640px reasonable for miniatures?
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.
