If you publish photography, product shots or design work online, your images will be reposted without credit — the question is only whether your name travels with them. A watermark is the cheapest insurance: even a scraped image keeps advertising where it came from.
But watermarks are easy to ruin. Too subtle and nobody sees them; too aggressive and the photo becomes an ad for your insecurity. Here's the balanced approach, applied in bulk, locally in your browser.
Text or logo watermark?
- Text watermark — your name, brand or handle. Fast, works instantly for batch jobs, no asset needed. Start here.
- Logo watermark — a PNG with transparency, ideally wordmark or symbol only. More professional once you have the asset; requires designing for legibility on both light and dark photos.
Adding a text watermark
1. Open the tool
Go to Watermark with Text and drop one or hundreds of photos.
2. Write the text and pick position
Your name or brand. Position: bottom-right or bottom-left corner is the standard — visible but outside the subject. Center placement is maximum deterrence but ruins the image; bottom corners survive casual cropping attempts while keeping the photo usable.
3. Tune size and opacity
- Size: 4–8% of the image's smaller dimension. Big enough to read, small enough to ignore.
- Opacity: 50–70%. Below 40% disappears on bright skies; above 80% fights the photo for attention.
- Color: white with a subtle shadow, or black on light images. If the tool offers a background plate, a rounded semi-transparent strip is more legible than raw text over busy areas.
4. Choose output format and download
JPG at quality ~90 for photos; PNG if the images have transparency. Batch results download individually or as a ZIP.
Adding a logo watermark
1. Prepare a transparent PNG
Your logo as PNG with an alpha channel, black or white monochrome versions work best. A JPEG logo means a white box on every photo — don't.
2. Open the image watermark tool
Watermark with Image accepts the PNG plus your photo batch. Scale to ~15–25% of the image width, place in a corner, opacity 60–80% (logos are usually bolder than text and tolerate higher opacity).
3. Consider a two-format output
For public galleries, some photographers export a heavily-watermarked preview set and a clean set for clients — the batch tooling makes generating both trivial.
Watermark placement rules that survive cropping
Sophisticated scrapers crop corners to remove watermarks. Countermeasures that don't ruin the image:
- Tile it subtly across the image at low opacity for preview sets (portfolios, stock-style)
- Vary the position between images so a single crop script can't clean the whole gallery
- Pair with metadata: a watermark is visual, EXIF copyright is invisible — set both. (Then read the EXIF privacy guide to decide what else stays in that metadata — GPS coordinates should not.)
What a watermark can't do
Honesty section: a corner watermark is removed by a determined editor in 30 seconds. It is a deterrent and an attribution mechanism, not DRM. If licensing enforcement matters, register copyright where applicable and keep originals with timestamps. The watermark's real job: when image #347 of your set goes viral on a forum, the 20 people who see it can find you.
FAQ
Will watermarking compress or resize my photos?
No — dimensions and quality are preserved (PNG stays PNG, JPG re-encodes at quality 92 by default). For publishing, compress after watermarking with the Bulk Image Compressor.
Do my photos get uploaded?
No. Watermarking is pure canvas drawing in your browser — nothing is transmitted, and it works offline.
Can I watermark 500 photos at once?
Yes. Every file in the batch gets identical watermark settings, which is exactly what you want for a consistent look.
Should I watermark Instagram posts?
Mild corner watermark, yes — platform reposting strips captions but keeps pixels. Keep it small enough that the platform's own compression doesn't smear it into artifacts.
