Intent-accurate annotation

Image Annotator places labeled pin markers — not freehand shapes, arrows, or blur tools. For screenshot feedback and tutorials, callouts with text labels are faster to place and stay sharp at any size.

Why annotate images in the browser?

Most online editors route your file through a remote server. Pix-8 keeps annotation local — the core advantage when you need to annotate images online freewithout compromising confidentiality.

Privacy by architecture

Client-side processing only. Your screenshots, mockups, and internal assets never touch a cloud server.

Instant, upload-free speed

No queue, no round-trip latency. Click to tag, drag to reposition, and export in seconds.

Labeled callouts, not clutter

Pin markers with readable text labels — built for feedback, tutorials, and QA without a drawing canvas.
