How to Watermark Photos in Bulk (Text or Logo)
Use a small, semi transparent watermark in a corner for portfolios and social posts, and a tiled diagonal watermark for client proofs and stock previews. Apply it to the whole batch at once so every photo matches.
Why watermark at all?
A watermark credits your work when it is shared, discourages casual reuse and brands your photos on social media. For client proofs, a strong watermark protects images until they are paid for.
Corner or tiled?
A corner watermark at 60 to 80% opacity is subtle and suits portfolios, social posts and product photos.
A tiled watermark repeated diagonally across the whole image is much harder to crop or erase, which makes it the right choice for proofs and previews.
Watermark a batch with SleekCut
1. Open Watermark Photos and drop all your photos.
2. Type your name or choose a logo, ideally a PNG with a transparent background.
3. Choose a position, size and opacity, and check the live preview. Click other photos in the strip to see how it looks on each.
4. Press Watermark all and download the ZIP.
Size and readability
The watermark scales with each photo, so portrait and landscape shots get the same look. White text with a soft shadow reads on most photos; switch to black for bright, light backgrounds.
Keep your originals
SleekCut creates watermarked copies and never changes your originals. Keep a clean archive and only share the watermarked versions.
