Frequently Asked Questions
Explore comprehensive answers, technical specifications, and helpful guidance for processing your documents.
What markup tools are available for annotating images?
You can draw arrows, rectangles, circles, freehand sketches, highlighters, and callout text directly onto your screenshots or graphics.
Can I blur sensitive information while annotating?
Yes. The annotation toolbar includes a blur brush and solid-shape tool, so you can paint over faces, license plates, IDs, or passwords before sharing. Blur is applied to real pixels during export, not as a removable overlay, which makes the redaction permanent.
Does annotating images require account registration?
No account is needed. Open the page, drop an image, and start drawing arrows, boxes, or text immediately. There is no sign-up, email gate, or session limit, because all rendering happens locally in your browser rather than on a processing server.
What image formats can I annotate and export?
PNG and JPEG inputs can be annotated, and finished work exports as either a lossless PNG for crisp line art or a compressed JPG for sharing. The canvas pipeline keeps your original resolution intact, so screenshots and photos stay sharp at full size.
