FAQ
Are files sent to a server?
No. File contents, file names, document text, searches, and passwords are not sent or stored.
Can I edit PDF text or insert images?
Open a PDF and choose Edit. Change detected horizontal text or add text and images. Drag an image to move it and pull its corners to resize it. Changed and added text uses Noto Sans KR. Grouped or vertical text and words inside scanned images cannot be edited directly. Choose Finish editing, review the result, then Save.
Can I search scanned PDFs?
OCR is not supported, so text search is limited in image-only scanned documents.
Can I edit a signed PDF?
Editing text, inserting images, rotating, deleting, rearranging, or re-saving pages can invalidate a digital signature. Keep the signed original separately.
