A Complete Markup Toolkit

Everything you need to explain an image clearly.

Precise Annotations

Arrows, lines, boxes, ellipses, text labels, numbered steps, highlighter, and freehand pencil — every tool you reach for, drawn pixel-accurately.

Redact with Confidence

Blur or pixelate sensitive details before you share. Keep private information out of every screenshot you send.

Draw the Eye

Spotlight to dim everything but the focus, a magnifying loupe for fine detail, callout bubbles, measure, and emoji or image stamps.

A Real Editor

Save editable .ularmark documents and reopen them later with every annotation, the zoom level, and the source image still fully editable. Full undo/redo.

Common Questions

Where are my images stored? Everything stays on your device. UlarMark only opens images you choose and only writes files you explicitly save or export. Nothing is uploaded. Is it a subscription? No. UlarMark is a one-time purchase on the Mac App Store — buy it once and own it, with no subscription and no in-app purchases. What can I open? Paste from the clipboard or open PNG, JPEG, TIFF, GIF, HEIC, WebP, BMP, and more — via the Open panel, Finder "Open With", or drag-and-drop. Does it speak my language? UlarMark ships with 18 interface languages and picks yours automatically from your system settings.
