IconVault's Bulk Watermark stamps a repeating tiled pattern across many photos at once, then downloads them all as a ZIP. A full-image tile grid is much harder to crop out than a single corner mark. Set the size, color, opacity, spacing and angle once and it applies to every photo. Everything runs free and browser-private, your photos never leave your device.

Use your own text or logo, with 8 fonts to choose from, and preview the pattern live before you watermark the batch. Pro members get unlimited use with no trial limits.
