How to add a watermark
Add photos
Choose one or more photos or drop them in the box.
Design the mark
Type the text or pick your logo, then its position, size and opacity. The preview updates as you go.
Download
Download the current photo, or all watermarked photos in a ZIP.
Tips for a good watermark
40–70% opacity. The mark stays readable without hiding the photo’s detail.
Tiling protects more. A corner mark is easy to crop off. A tiled, angled mark over the whole photo is harder to remove and suits product photos and documents.
Use a transparent PNG logo. If your logo has a white background, remove it first, or use text instead.
FAQ
How do I put my logo on many photos at once?
Add all the photos, choose “Logo” and your logo file, set position and size, then “Download all images (ZIP)”. The logo gets the same proportions on every photo, whatever its size.
Is resolution lost?
No. Every photo keeps its full original dimensions. PNG is lossless; JPG uses the quality you choose (92% by default).
Can the watermark be removed later?
Not easily from the new photo: it is part of the pixels. But no watermark fully stops copying; it deters and shows where the photo came from. Keep your original without the mark.
Does it support Arabic text?
Yes. Arabic letters are joined and drawn in the right direction, and you can write two lines.
Are my photos or logo uploaded?
No. Everything runs inside your browser; the files never leave your device.
