Before you begin
Screenshot editing is available in the current App Store release and requires Pro on iPhone/iPad, as do terminal attachments. The destination server needs SFTP and a writable folder.
Choose the right terminal and image
Open the intended terminal. From its attachment action (available in ⋮), choose Edit screenshot before uploading and select a still image. For an already open Web preview, choose Capture & annotate… in Preview actions. This captures the visible viewport, not a full scrolling page.
Crop, point out, or cover a detail
Use Crop to reduce the image, Arrow or Box to point out the issue, and Cover to hide sensitive content. Undo and redo let you review changes; the original image remains unchanged. Inspect every visible secret before sharing.
Review before uploading
Tap Next. Check the destination host and directory in the confirmation. Upload is explicit; cancelling here does not upload the edited image. The result is a flattened PNG, not the original editable layers.
Explain what should change
If Compose after upload is selected, add your instructions to the draft containing the remote reference. Tap Insert deliberately. It inserts into the intended terminal without pressing Enter; inspect the terminal and send yourself. At a plain shell prompt, do not execute a file path as a command.
If something gets in the way
The image cannot be edited
Use a still PNG or JPEG within the editor’s size limits (16 MB and 8 megapixels). Download cloud-backed images first. Choose files is a separate original-file upload path.
The host or connection changed
Stop and verify the target. Reconnect, reopen Compose and review the retained draft; never send to another server just to dismiss an error.
Is ordinary upload still free?
Yes. Files → More actions → Upload files remains free. Advanced editing and terminal attachment convenience require mobile Pro.
