Arrowbox review
A focused free tool for marking up multiple images offline and exporting clean files.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Arrowbox is a free, browser-based screenshot annotation tool for individuals who need to mark up, redact, and export images without uploading them. Users can paste, drag, or open multiple screenshots on one board, then add arrows, callouts, text boxes, rectangles, ellipses, highlights, and auto-numbered step stamps. The tool runs locally in the browser, requires no account, and exports flattened PNG, JPEG, or PDF files without a watermark.
Its strongest area is focused annotation depth. Arrows support configurable head and tail styles, while callouts combine text with elbow leaders for clearer explanations. Redaction offers solid black, blur, or pixelation, and redacted pixels are destroyed in exported files. A saved self-contained HTML file enables offline operation, which suits repeat work on a local machine or in environments where images should not be uploaded. The free plan includes screenshot annotation, redaction, exports, and no-account use at a price of $0.
Arrowbox is a good choice when the workflow starts with existing screenshots and ends with a straightforward image or document export. It is less suitable for users who need capture functionality, browser-extension support, or integrations with other software. The product keeps its scope narrow rather than extending into a broader capture or connected workflow, so its appeal is clearest for simple, self-contained markups across multiple images.
