FAQ

Questions about this tool

Does this upload my screenshot?
No. The image, marks and PNG are processed in this browser tab. No account, image upload, analytics or watermark is required. The page loads its software, fonts and optional fictional sample from this website.
Which image files can I use?
PNG, JPEG and WebP files can be up to 20 MiB, 40 million pixels and 16,384 pixels on either side. Large images can still exceed the memory available on your device. The output keeps the original dimensions. Export has a 120-second deadline; cancel or try a smaller image if processing fails.
How many marks can I add?
You can add up to 100 arrows, text labels and rectangles. Text can contain up to 2,000 characters. Undo keeps the latest 100 changes. A different source image clears the marks and history.
Can I use the keyboard?
Focus the canvas or mark list. V/R/A/T choose tools and Enter inserts a mark. Arrow keys move the selection by one pixel, Shift moves ten. Delete removes a mark, Ctrl or Cmd+Z undoes and Shift+Z redoes. Text fields keep their usual editing shortcuts.
Can I save an editable project or share a hosted link?
This tool downloads a flattened PNG. Synced capture editing, cloud history, team workspaces and hosted links are separate paid features.
