100% private
Images are processed by Web Workers inside your browser. They are never uploaded, stored or seen by anyone – not even us.
Your photos never leave your device

Everything you need to protect your photos
Text & logo layers
Combine text and logos. Choose from signature, display and classic fonts or upload your own font and brand logo (PNG or SVG).
Tiled patterns
Repeat your watermark across the whole photo at any angle and spacing – the hardest kind of watermark to crop or remove.
Bulk watermarking
Premium watermarks up to 50 photos at once using every core of your CPU, then downloads them as a single ZIP.
Pro-grade controls
Opacity, rotation, blend modes, outline, shadow, background labels, margins, placeholders like {year} and {filename}.
Works everywhere
Phone, tablet or desktop – no app to install. Exports strip GPS and camera metadata so your location stays private too.

Frequently asked questions
Are my images uploaded to your server?
No. Your images are decoded, watermarked and encoded entirely inside your browser using Web Workers. Our server only stores your account (email and an encrypted password), your subscription status and a count of how many images you watermarked – never the images themselves, their names or their content.
Is it free?
Yes. A free account can watermark 5 images per rolling hour, one at a time, with ads. Premium removes ads, lifts the hourly limit and unlocks bulk watermarking of up to 50 images at once.
What does "rolling hour" mean?
Each image you download counts for exactly 60 minutes. If you used all 5, the next slot opens 60 minutes after your oldest download – you never have to wait for a fixed reset time.
Which file formats are supported?
Any image your browser can open: JPG, PNG, WebP, GIF and AVIF (and HEIC on Safari). You can export as the original format, JPEG, PNG or WebP, and optionally resize while exporting.
Does watermarking reduce image quality?
Images are rendered at full resolution. PNG exports are lossless; for JPEG and WebP you control the quality (92% by default, visually lossless).
Is metadata removed?
Yes. Exported images contain no EXIF data, which means GPS location, camera serial numbers and similar details are removed.
