Image Watermark does one thing and does it well: it lets you add text watermark to images without the usual hassle. Here's how to get the most from it.
Protect your images with custom text watermarks — processed locally.
The part I like most? Everything runs right in your browser. Nothing gets uploaded to a server, so your files stay on your own device the whole time.
This guide walks through the whole thing: what it's for, how to use it step by step, a few tips I wish someone had told me earlier, and the questions people ask most.
What you're working with
Add text watermark to images. It works with JPG, PNG, and WebP files, which covers what most people need day to day.
It sits in the image tools corner of Daily Toolkits, so if you end up needing something related later, there's usually a matching tool a click away.
Step by step
You'll be through this in a couple of minutes. Here's how it goes:
- Select image. You can open it here: Image Watermark.
- Enter watermark text and position it.
- Download watermarked image. Open it once to make sure everything looks right.
Tips for better results
I've run into most of the common snags already, so here's what actually moves the needle:
- Keep a copy of the original before you start — it takes a second and saves you if you want to redo it.
- Start from the highest-quality source you have. Compressing an already-compressed image just stacks the damage.
- If the result isn't quite right, change one setting at a time so you know what made the difference.
- For photos, WebP usually gives you the best size-to-quality ratio these days.
- Resize before you compress — shrinking dimensions cuts file size far more than quality tweaks alone.
Where it comes in handy
Bloggers and shop owners who want pages that load fast without ugly, blurry images.
People clearing space or fixing photos before posting them online.
Anyone who needs a specific size or format for a profile, listing, or upload form.
Troubleshooting the annoying bits
Nothing here is a big deal, but these trip people up more than you'd think:
- Uploading the wrong version of a file. Close old tabs and double-check the filename first.
- Feeding it a format it doesn't handle. Stick to JPG, PNG, and WebP and convert first if needed.
- Expecting perfection on the first pass. If it's not right, adjust one option and run it again — that's normal.
- Closing the tab too early. Let it finish before you navigate away, especially on slower connections.
