Sealer: Photo Watermark

Stamp a batch. Preview first. Originals stay untouched.

Sealer stamps a watermark on a batch of photos in under a minute — and never touches your originals.

Pick photos, add text or a logo, preview the stamp, then save new copies or share. Built for creators, photographers, and small businesses who need a clean mark before Instagram, client galleries, or listings.

WHY SEALER • Batch watermark dozens of photos in one flow • Text stamp with position, size, and opacity • Preview before you commit — no silent overwrite • Saves new copies only; originals stay untouched • Logo / PNG stamp on Pro • No account. No AI. No cloud. Photos never leave your phone.

SEALER PRO Sealer Pro features require an additional purchase. Choose a monthly auto-renewing subscription or a one-time lifetime purchase.

Stamp every photo. Keep every original.
