How to Add a Watermark to Your Photos

Why watermark?

• Credit. Photos get shared, screenshotted and reposted. A watermark carries your name with them.
• Deterrence. A visible mark makes casual copying less attractive, especially for commercial use.
• Marketing. A small shop or photographer’s web address on every image turns shares into advertising.
• Proofs. Photographers send watermarked previews so clients can choose before paying for clean files.
• Protecting documents. A copy of your passport marked “For rental application at 12 Smith St only” is far less useful to anyone who intercepts it.

How to add a watermark

1. Open Watermark Image and add your photos — up to 30 at a time.
2. Type your watermark text, for example “© Priya Shah Photography” or “priyashah.com”.
3. Choose a position: a corner, the top or bottom centre, or the middle.
4. Adjust size (as a percentage of the image), opacity and colour.
5. Tick Repeat across the whole image if you want the text tiled diagonally over the entire photo.
6. Choose the output format and download each image or all of them together.

Because the size is set as a percentage of each image, the watermark looks consistent across a batch of photos in different sizes and orientations. The watermark is text only — if you need a logo, use a text version of your brand name or web address.

Corner mark or tiled watermark?

A corner watermark can be cropped off in seconds, so it’s mainly about credit, not protection. A tiled watermark is much harder to remove, but it also spoils the image for everyone — which is exactly the point for client proofs and document copies, and exactly wrong for a portfolio.

Getting the look right

• White text at 50–60% opacity works on most photos. Use dark text on very light images like snow scenes or product shots on white.
• Size 3–6% for a corner mark; it should be readable but not the first thing you see.
• Keep it short. A name or web address is enough — “© 2026 Priya Shah Photography, all rights reserved, do not copy” is clutter.
• Check against the photo. If the corner you’ve picked is busy or the same colour as your text, choose another corner.

Watermarking copies of your ID and documents

Landlords, employers, agencies and banks often ask for copies of passports, driving licences and payslips. A copy sitting in someone’s inbox can be misused if their email is ever compromised. A tiled watermark that says who the copy is for and when makes it much less useful to anyone else:

• “Copy for ABC Rentals — rental application — 27 Sep 2026”
• “For employment check at XYZ Ltd only”

Set a low opacity (about 25–35%) so every detail stays readable to the person who legitimately needs it, and tick Repeat across the whole image. Before sending, check that the watermark doesn’t cover the photo or numbers so badly that the document is rejected — the aim is to label the copy, not obscure it. For documents that are already PDFs, use Watermark PDF to stamp every page.

Only watermark copies of your own documents, and send the originals unaltered wherever originals are required.

What a watermark doesn’t do

In most countries, you own the copyright in photos you take automatically — you don’t need a watermark or a © symbol for that. What a watermark adds is evidence of authorship and a practical nudge. In some countries, such as the United States, removing a watermark to hide who owns a work can itself break copyright law, but a watermark is still a deterrent, not a lock. Anyone determined can crop, paint over or re-photograph an image. For photos you really don’t want copied, share smaller, lower-resolution versions and keep full-size originals private.

Watermarks for social media

Social platforms shrink and re-compress everything you upload, and they show images in feeds at a fraction of their real size. A watermark that looks right on your screen at full size can become an unreadable smudge in a feed. Before posting, preview the watermarked image at phone-feed size: if your name isn’t readable, increase the size a step or raise the opacity. Also avoid the very bottom edge on platforms that overlay captions, buttons or a progress bar there — a bottom-left or bottom-right mark slightly in from the edge is safer, and the top corners are often clear.

For a consistent look across a whole account, save your settings as a note — text, position, size, opacity and colour — and use the same ones every time. Consistency is what makes a watermark read as a brand rather than an afterthought.

Workflow: resize first, then watermark

1. Crop and edit the photo first — cropping after watermarking might cut the mark off.
2. Resize for where it’s going with the Image Resizer. 2048 pixels on the long side suits most websites and social media.
3. Watermark the resized copies.
4. Remove location data from the originals you’re sharing with the EXIF Remover, if they’re going out unwatermarked elsewhere.
5. Keep the unwatermarked originals in a separate folder — you can’t reliably remove a watermark later, so never overwrite them.

Worked example: a small online shop

Priya sells handmade ceramics and has found her product photos on other sites more than once. She has 24 new photos to upload.

1. She resizes all 24 to 2000 pixels on the long side.
2. In Watermark Image, she types “priyashahceramics.com”, chooses bottom-right, size 4%, white at 60% opacity.
3. She checks the first photo — on a white-glazed bowl the text disappears — so she downloads that one separately with dark grey text.
4. For wholesale buyers, she makes a second set with the text tiled at 25% opacity, marked “Preview — not for resale”.

Now, when her photos are shared, her web address goes with them — and a few new customers have found her that way.

Common mistakes

• A watermark so big and opaque it ruins portfolio photos.
• A watermark so small and faint it disappears when the image is shrunk for social media.
• Watermarking the only copy of a photo.
• Placing the mark where it’s easy to crop without losing anything important.
• Using a watermark with an old business name or dead web address.

Privacy

Watermark Image runs in your browser, so your photos — and any ID or document copies — aren’t uploaded to a server to be watermarked.
