Sizes are relative, so the watermark looks the same on every image whatever its resolution.
Your images never leave this device.
Add your hotline and website to product images
When your images are shared in Facebook groups, on Zalo or on marketplaces, they often lose the link back to you. Putting your phone number and website on the image itself ("chèn số điện thoại vào ảnh") means every repost can still bring customers back to your shop.
Type up to two lines, such as a hotline and a website, and turn on the background box so the text stays readable on both light and dark photos. Place it at the bottom center or in a corner so it never covers the product.
Your photos never leave your device
Watermarking usually happens right before publishing, while photos are still unreleased product shots, client work or personal documents. Upload-based tools copy those files to someone else's server. Here every image is decoded, stamped and saved inside your browser's memory, and nothing is uploaded. Output keeps the exact original pixel dimensions, and camera metadata such as GPS location is removed from the exported files.
Frequently asked questions
How do I add two lines of text?
Press Enter in the text box to start a new line, for example "Hotline: 0909 123 456" on the first line and your website on the second.
Why can't I read my text on some photos?
White text disappears on bright backgrounds. Turn on Background box, which places a semi-transparent panel behind the text, or turn on Soft shadow.
Can I write in Vietnamese?
Yes. Vietnamese text with accents is supported in every font option, so you can write "Liên hệ" or "Giao hàng toàn quốc" directly.
