截记 SnapMark

Watermark, mosaic, batch editing — get your screenshots share-ready in seconds. Fully offline, nothing leaves your device.

SnapMark is a clean, focused screenshot annotation tool.

Got a screenshot to share, but it contains something others shouldn't see? SnapMark lets you quickly add a mosaic over sensitive areas, stamp a "Confidential" watermark, then save or share — all in a few taps.

KEY FEATURES • Watermark: Built-in presets or fully custom text. Drag to position anywhere, or snap to a corner. Adjust opacity to taste. • Mosaic: Draw over any area to blur sensitive content. • Batch: Long-press to select up to 9 screenshots and apply a watermark to all at once. • Share Extension: Trigger SnapMark directly from the share sheet in any app — no switching required.

PRIVACY FIRST SnapMark runs completely offline. No network access, no data collection. Your images never leave your device.
