How to watermark your photos
1
Enter your markType your name, @handle or brand — the text that will protect the photo.
2
Tune size & opacityPick how large it should be and how see-through. 40–60% reads clearly without hiding the image.
3
Set position & colourBottom-right is the convention; choose a colour that contrasts with your photos.
4
Batch-stamp & downloadAdd as many photos as you want — every one gets the same clean mark.

Watermark

Size is a percentage of each image's width, so 5% looks the same on a 600 px thumbnail and a 6000 px original.

What a watermark actually does (and what it doesn't)

A watermark protects your name, not your pixelsTreat it as a deterrent plus a credit line. If you only need proof of ownership and care about a clean look, a small semi-transparent mark in one corner is the professional sweet spot.

A watermark is a deterrent, not a lock. It will not stop a determined thief with editing software, but it removes the easiest kind of theft — someone saving your photo and reposting it without attribution. It also means that wherever the image travels, your name travels with it.

That distinction matters legally. In most jurisdictions, adding a watermark does not create or transfer copyright; you already own the copyright to photos you took. What the watermark does is make ownership visible and make a claim of "I didn't know it was someone else's" much harder to sustain.

Making it effective

  • Keep it legible but not dominant. Around 40–60% opacity on a contrasting area reads clearly without wrecking the photo.
  • Use a subtle drop shadow. A white mark disappears on snow and a black one vanishes into shadow. SnapTools adds a soft shadow automatically so the text survives both.
  • Position it where cropping hurts. Bottom-right is the convention and the easiest corner to crop away. If theft is a real concern, consider placing it across a key part of the subject.
  • Use one consistent mark. Recognition comes from repetition — the same text in the same place builds association over time.

Text vs logo watermark

This tool adds text, which is fast, scales cleanly and never looks blurry. Logo watermarks look more branded but need a transparent PNG and careful scaling for each image size. For most creators, plain text in a consistent font is the better everyday choice.

Be careful with client work. Never watermark images you do not own or have not been licensed to publish. Adding your mark to someone else's photograph can create its own legal problem.

Frequently asked questions

Is watermarking free?
Yes. There is no charge, no account and no limit on how many images you stamp. The tool never adds branding or a watermark of its own to your output.
Are my photos uploaded to a server?
No. Each image is watermarked in your browser and never leaves your device. That matters most when the photos are unreleased client work or a personal gallery.
Can I watermark many photos at once?
Yes. Select or drag in a batch and the same text, size, colour, opacity and position is applied to every image in a single pass.
Can I use a logo image instead of text?
Not yet — this tool stamps text watermarks only. Size, colour, opacity and one of five positions can all be adjusted, and the size is a percentage of image width so it looks the same on a 600 px thumbnail and a 6000 px original.
Where is the best place to put the watermark?
Bottom-right is the least intrusive for simple branding. A centre watermark at higher opacity is the better choice when the goal is to make the image genuinely hard to reuse without permission.
Can the watermark be removed later?
The mark is drawn into the exported pixels, so it is not a layer you can switch off — which is the point. Your originals are never modified, so you always keep a clean copy.
