Product photos get copied by other shops, travel photos get reposted without credit, and portfolio images turn up in someone else's ads. A watermark won't stop a determined thief, but it makes casual copying less attractive and puts your name on every share.
Text or logo?
- Text — your name, @handle or website. Quick to set up and works in any language, accents included.
- Logo — looks more professional for a brand. Use a PNG with a transparent background; a JPG logo shows its background as a white or coloured box.
Where to put it
- Corner — clean and unobtrusive, good for portfolios and social posts. The downside: it can be cropped off.
- Centre — harder to remove but more distracting; works well at low opacity.
- Tiled across the photo — the hardest to crop or edit out. Best for product photos, proofs sent to clients and anything that's likely to be stolen.
Size and opacity
A watermark should be readable, not the subject. Good starting points:
- Corner logo: around 15–20% of the photo width, 60–80% opacity.
- Tiled text: diagonal, smaller text, 20–30% opacity.
Because the size is set as a percentage of the width, the watermark looks the same on large and small images.
How to watermark photos in a batch
- Open Add Watermark to Image and choose up to 20 photos (JPG, PNG or WebP, up to 30 MB each).
- Type your text and pick a colour — or upload your logo.
- Choose a corner, the centre or tiled, then adjust rotation, size and opacity while watching the live preview on the first photo.
- Click Add watermark.
- Download each photo, or all of them at once as a ZIP.
JPG stays JPG, and PNG and WebP keep their transparency. Photos are re-saved at high quality (92% for JPG and WebP; PNG is lossless) at their original size, and phone photos stay the right way up.
A good workflow before posting
- Remove location data with the EXIF Remover, so your photos don't reveal where you live.
- Crop to the platform's ratio with Crop Image.
- Watermark last, so the mark isn't cropped away.
- Compress if needed with Image Compressor.
FAQ
Are my photos uploaded? No. Your photos and logo are processed in your browser and never uploaded.
Can I watermark a PDF instead? Yes, with Add Watermark to PDF.
Will a watermark hurt engagement? A small, semi-transparent corner mark rarely does. Large, opaque marks can — save those for proofs.
