A watermark's job is to mark ownership without wrecking the picture. Get the balance right — visible enough to deter casual theft, subtle enough that people still enjoy the image — and you protect your work while keeping it presentable. Get it wrong and you either slap an ugly logo across a nice photo or add a mark so faint anyone can crop it off in seconds.
Here's how to do it properly, plus how to watermark a whole folder in one go.
Text or logo — which to use?
Both work; they signal slightly different things.
- Text watermark — your name, your handle, a URL, or a copyright line. Best when you want people to know who made the image and where to find you. It's searchable when someone reads it, and it doubles as free promotion.
- Logo / image watermark — your brand mark as a semi-transparent overlay. Best for a consistent visual identity across a portfolio or shop. It reads instantly and looks more polished on professional work.
If you're a photographer or creator building a name, text with your handle or site is often the most useful. If you have a brand, use the logo. Nothing stops you from combining a small logo with a URL line.
Corner or tiled — the protection trade-off
Where you place the mark decides how hard it is to remove.
Corner placement looks clean and professional. One discreet mark in a bottom corner, low opacity, out of the way of the subject. The downside: it's the easiest thing in the world to crop out. For low-stakes sharing where you mostly want attribution, a corner mark is fine.
Tiling repeats the watermark across the entire image in a grid. It's more intrusive, but it's genuinely protective — you can't crop away a mark that covers the whole frame, and removing it cleanly is real work. Use tiling for images you actually need to protect: preview shots of paid work, proofs sent to clients before payment, stock you don't want lifted.
A practical rule: corner for showcase, tile for protection. If someone downloading the image and reusing it would cost you money, tile it.
Getting the settings right
Three controls decide whether a watermark protects or annoys:
- Opacity — the single most important setting. Too solid and it dominates the photo; too faint and it's useless. Somewhere around 30–50% usually reads clearly while letting the image breathe. Tiled marks can go lower because there are many of them.
- Size — big enough to read, small enough not to fight the subject. For a corner mark, keep it modest. For tiling, medium marks spaced out work better than a few huge ones.
- Rotation — a slight angle (say 30–45°) on a tiled watermark makes it noticeably harder to clone out or crop around than a straight horizontal one.
The Watermark tool gives you all of these — text or image, corner or tile, plus size, opacity, and rotation — so you can dial in exactly the balance you want and see it before you export.
Watermark a whole folder at once
Marking one image is easy. The real time-saver is doing fifty. The tool supports batch processing: load a set of photos, apply your watermark settings once, and it stamps every image the same way. You get them back as a ZIP, ready to upload.
This is the difference between watermarking being a chore and being an afterthought. Photographers delivering a proofing gallery, shops preparing a catalog, anyone posting a series — set it once, run the batch, download the ZIP.
Because it all runs in your browser, your photos are never uploaded to a server. That matters for watermarking specifically: the whole point is protecting your images, so it would be odd to hand the unmarked originals to a stranger's server first. Here, they stay on your machine, and after your first visit the tool works offline too.
Quick checklist
- Pick text or logo — text to be found, logo for brand identity.
- Choose placement — corner to showcase, tile to protect.
- Set opacity around 30–50% — visible but not overpowering.
- Angle a tiled mark — harder to remove.
- Batch the rest — apply once, download the ZIP.
A good watermark is one people barely notice until they think about stealing the image. Set it thoughtfully once, then let the batch handle the volume.
