Frequently Asked Questions

What type of watermarks can I add?
Custom text watermarks with any content — brand names, store names, account handles, copyright notices. Spaces and symbols can form simple patterns for varied protection needs.
How do I add a semi-transparent watermark?
Upload the image, type your text and drag the opacity slider (5%-90%) for a translucent effect that protects without hiding the subject. 30%-50% suits most brand marks.
Can the watermark be placed anywhere?
Yes — presets for center, corners and edges plus free dragging. Consistent placement across images is great for e-commerce galleries and portfolios.
Does adding a watermark damage the original?
No. A new image is generated; your original stays untouched. Download the watermarked copy and keep the clean master for later use.
Is watermarking safe? Will images upload?
Safe. Processing runs locally in your browser; images never reach a server, suitable for unpublished photography, drafts and commercial assets.
Does the watermark support Chinese text?
Yes. Chinese characters render with SimHei/SimSun fonts, with adjustable size, color (black/white/gray/red/blue) and opacity.
Are there limits on free watermarking?
None. Free, no registration, unlimited images and watermarks — built for photographers, designers, sellers and bloggers.
Which images benefit most?
Photography, design drafts, e-commerce main images, course materials and tutorial screenshots needing copyright or brand marks.
