Photo Batch Watermark is a native Mac app for applying the same watermark to many photos at once — text or logo — with a live before/after preview
Photo Batch Watermark is a native Mac app for applying the same watermark to many photos at once — text or logo — with a live before/after preview.
Protect proofs, brand client deliveries, or stamp copyright on an entire shoot without opening each file in an editor.
How it works
• Add photos — Drop images into the library or use Add Photos. Photos stay in their original location on your Mac.
• Choose watermark type — Text (label, color, font, size) or Image (PNG/JPEG logo with adjustable size).
• Preview — Select any photo in the library. See the original and watermarked version side by side before exporting.
• Pick export folder — Choose where watermarked copies are saved.
• Generate — Export every photo in the library in one step. Files are saved with a _watermarked suffix. Originals are never modified.
Why Photo Batch Watermark
• Built for batches — One watermark setup, many photos.
• Preview first — Check text, color, and placement on a real photo before exporting all.
• Safe export — Non-destructive; writes new files to your chosen folder.
• Native Mac app — SwiftUI, sandboxed, offline, no account.
• Photo workflow — Pairs with Photo Contact Sheet and Photo PDF Builder in The Beaver Tools suite.
Good for
