常见问题
Are my WebP images uploaded?
所有处理都在浏览器本地完成，无需上传文件。
Is 1600px reasonable for Facebook?
Yes. It is a practical starting point for social posts and page uploads, 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.
