Opacity Balance
Recommended 30%-70% opacity. Too high provides no protection, too low affects aesthetics. Adjust based on background brightness for optimal effect

❓ Frequently Asked Questions
What image formats are supported?
Our tool supports common image formats: JPEG/JPG, PNG, WebP, GIF, and BMP. Maximum file size is 20MB with image dimensions up to 8192x8192 pixels.

Can watermarks be easily removed? How to enhance protection?
While watermarks can be technically removed, smart design greatly increases difficulty: 1) Use semi-transparent effects that blend with background; 2) Place in complex background areas; 3) Use multiple small watermarks distributed; 4) Combine with legal statements. Professional thieves may try, but it stops 99% of casual users.
Watermarks affect image beauty - how to balance protection and aesthetics?
This is every creator's common pain point. Suggestions: 1) Use 30-50% opacity - visible yet unobtrusive; 2) Choose image edges or solid color areas; 3) Keep fonts clean and professional; 4) Create subtle contrast with background. Remember, subtle watermarks look more professional than obvious ones.
Social platforms show authors already - still need watermarks?
Still valuable! Reasons: 1) Original source info is lost when images are saved; 2) Watermarks are the only identifier during cross-platform sharing; 3) Helps with brand promotion and follower growth; 4) Enables source tracking during secondary distribution. Recommend more refined, subtle watermark styles.
Can I batch process watermarks?
Current version focuses on single-image fine processing, ensuring each image gets optimal results. For batch needs, suggest: 1) Debug optimal parameters with one image first; 2) Record settings and repeatedly apply; 3) Consider browser bookmarks to save common configs. We're developing batch functionality.
What format is the watermarked image?
Watermarked images are saved in PNG format, which supports transparency and ensures optimal watermark quality while maintaining good compatibility.
