How to use
1. Pick a spec. A marketplace preset — Xianyu 1200×1200, Taobao 800×800, Pinduoduo 750×750, Xiaohongshu 3:4, Douyin 9:16 — or custom dimensions for any other platform (2000×2000 works for Amazon zoom-ready images).
2. Choose the fill mode. Pad scales the photo proportionally and fills the rest with your background color — the standard way to build white-background main images. Crop fills the frame from the center.
3. Add a watermark (optional). Any of 9 positions, or 30° tiled mode to cover the whole image. Around 20–30% opacity protects without hiding the product.
4. Export. JPG with a quality slider, or lossless PNG. One click generates all four marketplace images — Xianyu, Taobao, Pinduoduo and Xiaohongshu.

Type your text, pick one of 9 positions. For stronger protection use 30° tiled mode.
Catalogs look consistent and the product reads clearly. Pad mode letterboxes your photo onto white automatically.
