Watermark Tips
- • Use a transparent PNG logo for the cleanest look.
- • Bottom-right corner is the standard placement for photo credits.
- • Lower opacity (40-60%) reads as professional; higher draws more attention.
- • White text with a contrasting stroke stays legible on any background.
- • For large batches, watermark BEFORE resizing so the watermark scales with the image.
When to use batch watermarking
Photographers
Protect portfolio proofs and client previews before delivery. A semi-transparent signature or studio name at 35–50% opacity in a bottom-right anchor is standard.
Marketplace sellers
Stamp product photos with your store URL before listing on Etsy, eBay, Poshmark, or Facebook Marketplace. Discourages competitors from re-using your imagery.
Brand teams
Bulk-brand social media graphics, press kits, and event photos with a logo watermark. Consistent placement and opacity across hundreds of assets in one pass.

FAQ
Can I use both a text and logo watermark?
Yes. If both are set, the logo is drawn first and text is layered on top at the same anchor.
What logo file works best?
PNG with transparency works best. Both square and wide logos are supported.
How is the text readable on any background?
Text gets a contrast stroke, so it stays legible whether the background is light, dark, or mixed.
Are images uploaded?
No. Watermarking runs locally in your browser. Files never leave your device.
