❓ Frequently Asked Questions
How do I annotate a screenshot online?
▼
Upload your screenshot, select the Arrow tool, and click-drag to draw arrows pointing to important areas. Use the Box tool to highlight sections, and Text tool to add labels. All annotations are permanently applied when you download.
How do I draw arrows on an image online?
▼
Select the Arrow tool (it's the default on load), choose your color (red is most visible), adjust thickness with the slider, then click and drag from start to end point. A filled arrowhead renders automatically at the end point.
Can I annotate images on my phone?
▼
Yes — all drawing tools support touch events. Tap and drag to draw annotations on mobile. The canvas is touch-responsive for all tools including the pen and shape tools.
How do I add text labels to an image?
▼
Click the 'T Text' tool, type your label in the text input box that appears, then click anywhere on the image to place the text at that position. Adjust font size with the thickness slider.
What is the best format to download annotated images?
▼
PNG is the best format for annotated images — it preserves sharp edges on text and lines without JPEG compression artifacts. This is particularly important for screenshots with text annotations where blurring would be distracting.
