How it works

Mark Up a Screenshot in Three Steps

  1. 1

    Add a screenshot

    Paste, drop or choose an image — or open a result from another Shotexa tool without uploading it again.

  2. 2

    Point things out

    Add arrows, boxes, highlights, text, freehand notes and numbered steps. Select any mark to move, resize or restyle it.

  3. 3

    Export at full resolution

    Your marks are drawn onto the original pixels on your device and saved as a new image. The original stays untouched.

Questions

Annotating, answered

Can I change an annotation after adding it?
Yes. Every mark stays editable until you export: select it to move it, resize it, change its colour, or delete it. Undo and redo work for every change.
Will the text be sharp in the exported image?
Yes. Annotations are drawn at the full resolution of your screenshot when you export, not stretched up from the preview.
Are my screenshots uploaded?
No. Annotating and exporting happen in your browser. Your screenshot is not sent to a server.
How do numbered steps work?
Each new step marker takes the next number. Deleting a marker never silently renumbers the others; use Renumber when you want them to run 1, 2, 3 again.
