How to watermark an image
1
Upload your image from your device, or pull it from Google Drive, Dropbox, or OneDrive. JPG, PNG, WEBP, HEIC, BMP and TIFF are all supported - add one image, or up to three with a free account.
2
Type your watermark text - your name, brand, or a label like COPYRIGHT - or switch to image mode and upload your own logo. Pick a font size and colour to match the look you want.
3
Place the watermark: drag it anywhere on the image or snap it to a preset, then adjust opacity and rotation, and turn on mosaic mode to tile it across the whole image as an anti-copy pattern.
4
Preview the result in the editor. The watermark sits on a live overlay so you can fine-tune every setting before saving.
5
Click Add Watermark to apply. Download your image kept in its original format (or the whole batch as a ZIP), or save it back to the cloud.
Why use our Watermark Image tool
Custom text watermark
Type any text - your name, brand, or COPYRIGHT - to use as your mark. Style it with the font size, colour, and rotation that suit your photo.
Image & logo watermark
Prefer a logo? Upload your own image as the watermark, with one-click background removal so it sits cleanly over any photo.
Drag to position
Drag the watermark to any spot on the image, or snap it to one of nine presets - corner, centre, or edge. Tap a preset again to reset it.
Opacity slider
Take the watermark from fully solid to nearly invisible. Subtle marks read as a faint signature; solid marks stand out.
Rotation control
Tilt the watermark to any angle. Keep it upright, slant it slightly, or rotate fully diagonal for the classic stamp look.
Mosaic mode
Tile the watermark in a repeating grid across the whole image - the classic anti-copy pattern that is hard to crop out without losing part of the photo.
Pick any colour
Use brand red, signature black, or any colour you choose. The colour picker lets you match your photo or stand out boldly against it.
Many image formats
JPG, JPEG, PNG, WEBP, BMP, TIFF and HEIC all work. Output keeps the same format as the input - HEIC is saved as JPG, since browsers can't write HEIC.
Batch watermarking
Watermark up to three photos at once with a free account using the same settings, then download them together as a ZIP.
Live preview
See the watermark on a real preview of your image as you adjust position, opacity, and rotation - no guessing.
Original quality kept
Resolution and dimensions are preserved. The watermark is applied as a fresh overlay without re-compressing the rest of the image.
Private by design
Watermarking runs entirely in your browser - your photo is never uploaded unless you choose cloud import or sharing.

在手机浏览器（Safari、Chrome 等）中打开本页，从相册添加照片，设置水印后下载，无需安装 App，也支持 iPhone 的 HEIC 照片。
怎么用 Logo 做图片水印？
选择图片水印并上传 Logo，透明背景的 PNG 效果最好。调整大小和透明度后拖到合适位置。
水印怎么铺满整张图片？
开启平铺模式，水印会在整张照片上重复排列，更难被裁掉。也可以选择预设位置或直接拖动水印。
身份证照片怎么加水印更安全？
发送身份证、护照或驾照照片前，可在上面斜着写上“仅供办理某某业务使用”和日期，注明用途，降低被冒用的风险。
