Frequently Asked Questions
Are my images uploaded to a server?
No. All image processing happens locally in your browser. Your image data never leaves your device.
Which platform preset sizes are supported?
Built-in cover and avatar sizes for Xiaohongshu, Douyin, Weibo, WeChat Official Accounts and more, plus fully custom dimensions.
Will proportional scaling distort the image?
By default it scales proportionally by width. With Lock Ratio enabled, changing one dimension automatically calculates the other without distortion.
Can I upscale an image?
Yes. Note that upscaling clarity is limited by the original resolution, so it is best to work with images close to the target size.
