Add Watermark
Add text or logo watermark to images. Single or batch.
Add a text or logo watermark to a photo so your name, brand, or copyright travels with the image when it's shared or scraped. Use a single image or batch a whole folder at once with the same mark, and control opacity, size, and position so the watermark protects the work without burying it.
Watermarking happens entirely in your browser. Your images and your logo never leave your device, which matters when you're marking client proofs, unreleased designs, or paid work you don't want sitting on someone else's server. Nothing is uploaded.

About Add Watermark
Add a text or logo watermark to your photos to protect ownership before sharing online. Control position and opacity. Nothing is uploaded — the watermark is applied in your browser.
How to use the Add Watermark
- 1
Load your images
Drag in one photo or a batch. Batch mode applies the exact same watermark settings across every file, which is the fast way to mark a full set of proofs or product shots consistently.
- 2
Choose text or a logo
Type a text watermark (your name, website, or a copyright line) or upload a logo image, ideally a transparent PNG so only the mark shows and not a box around it.
- 3
Set opacity, size, and placement
Dial in how visible the mark is, where it sits, and whether it tiles across the whole image. Lower opacity is subtle; tiling and a centered mark are harder to crop out.
- 4
Export your watermarked images
Download the marked files, or the whole batch at once. The originals stay untouched on your device, so you always keep clean masters.
Opacity, placement, and tiling: what actually deters theft
A watermark is a trade-off between protection and looking good. A faint mark in one corner keeps the image attractive but is trivial to crop off, since the thief just cuts that corner. A bold, fully opaque mark across the center is nearly impossible to remove but ruins the viewing experience. The usual sweet spot is around 30 to 50 percent opacity so the image reads clearly while the mark is unmistakable.
For real deterrence, place the mark over the important part of the subject, not just a safe corner, so it can't be cropped away without destroying what makes the image valuable. Even stronger: tile the watermark so it repeats across the entire frame. A tiled, semi-transparent mark can't be cropped or easily cloned out, which is why stock-photo previews use it. Match the approach to the stakes, a light corner mark for casual sharing, tiled center marks for paid work you genuinely need to protect.
Text vs logo, and watermarking for batches
Text watermarks are quick, scale cleanly, and are great for a name, URL, or copyright line, which also doubles as free advertising when the image spreads. Logo watermarks carry brand recognition; upload a transparent PNG so the logo's shape shows without a rectangular background. Many people combine both, a logo plus a small URL line.
Batch mode is where this saves real time: set the watermark once and apply it identically to dozens of images, so an entire shoot or product catalog ships with consistent branding. Because it runs locally, large batches are limited only by your device's speed, not an upload connection or a per-image charge.
Quick tips
- ✓Aim for roughly 30 to 50 percent opacity. Visible enough to claim the image, light enough not to ruin it.
- ✓Place the mark over the subject, not in an empty corner. Corners are the first thing a thief crops off.
- ✓For work that really matters, tile the watermark across the whole image so it can't be cropped or cleanly cloned out.
- ✓Use a transparent PNG logo so you get the mark itself, not a white or black box around it.
- ✓Keep your originals. Watermark copies and archive the clean masters; you'll want unmarked versions for printing or licensing later.
Frequently asked questions
What opacity should a watermark be?
30–50% is standard — visible but not distracting. 100% looks heavy-handed and obscures the image.
Where should I place a watermark?
Bottom-right is the convention for photos. Avoid centering it across your main subject.
Does the watermark survive compression?
Yes — it becomes part of the image pixels, so it persists through resizing and compression.
Can I watermark many images at once?
Yes. Batch mode applies the same text or logo, opacity, and placement across every image you load, so a whole set comes out consistently branded in one pass.
What opacity and placement best prevent theft?
Around 30 to 50 percent opacity placed over the main subject, or tiled across the whole image, is hardest to remove. A faint corner mark looks nicer but is easy to crop off.
Are my images or logo uploaded anywhere?
No. Watermarking runs in your browser on your device. Your photos and logo never leave your machine, which is why it's safe for client proofs and unreleased work.
