Frequently asked
Does it work on scans?+
A scan has no text to snap to, so the dragged box itself becomes the highlight. Run the file through OCR PDF first if you want snapping.
Can I change the colour?+
Yes. Pick a marker colour from the panel, or any custom colour. Highlights let the text show through, on screen and in the download.
Is my file uploaded?+
No. The editor runs inside your browser, so the document never leaves your device. Edits are kept as a draft on your own device until you start over.
