¿Cómo funciona la herramienta de dibujo?
Esta herramienta utiliza la API Canvas integrada en tu navegador para dibujar trazos libres o líneas rectas directamente sobre tu imagen. Elige tu color y grosor, luego dibuja. Al exportar, el dibujo se renderiza a la resolución original de la imagen — tu imagen nunca se envía a ningún servidor.
Tips for Drawing on Images
- Choose the right brush size — Use a thin brush for precise annotations and a thicker brush for highlighting or redacting areas.
- Use contrasting colors — Pick a color that stands out against the image background for clearly visible annotations.
- Use the undo feature liberally — The undo button lets you step back through your drawing history for free experimentation.
- Add text annotations for clarity — Choose a font size large enough to read at the image's intended display size.
- Redact sensitive information carefully — Use solid-color rectangles to completely cover sensitive data with no gaps.
- Use shapes for professional annotations — Rectangles and circles draw attention more cleanly than freehand circles.
When to Draw on Your Images
- Bug reports and feedback — Annotate screenshots with arrows, circles, and text to clearly indicate UI issues or bugs.
- Redacting sensitive information — Cover personal data in screenshots before sharing them publicly or in support tickets.
- Educational content — Add labels, arrows, and explanatory text to diagrams for tutorials and presentations.
- Design review markup — Draw directly on design mockups to indicate changes during the review process.
- Social media content creation — Add fun doodles, text overlays, or emphasis markers to photos for social media.
Preguntas frecuentes
¿Mi imagen está segura?
Sí. Tu imagen nunca sale de tu dispositivo. Todo el dibujo y la exportación se realizan localmente en tu navegador usando la API Canvas. No se envían datos a ningún servidor.

What drawing tools are available?
ImgLab's draw tool includes a freehand brush with adjustable size and color, shape tools (rectangles, circles, lines, arrows), and a text tool for adding typed annotations. You can customize the color, stroke width, and opacity for each tool to match your needs.
What format is the annotated image exported as?
You can export your annotated image as JPEG, PNG, or WebP. PNG is recommended if your annotations include transparency or if you need pixel-perfect text rendering. JPEG works well for photos with simple annotations, and WebP provides the best file size.
Can I undo or redo my drawings?
Yes! The draw tool supports full undo and redo functionality. Each stroke, shape, or text element is tracked separately, so you can step back through your drawing history one action at a time. This makes it easy to experiment without fear of ruining your image.
Does drawing on an image change its resolution?
No — the exported image maintains the same resolution as the original. Your drawings are rendered at the image's native resolution, ensuring annotations look sharp and clear regardless of image size. The drawing canvas scales to fit your screen but always outputs at full resolution.
