よくある質問
Can I delete original PDF text?
Not as real glyphs. A text box with a solid fill (white by default) covers the old text in the exported file.
Does highlight search words?
No. Highlight is a colored rectangle you draw. It does not use OCR.
Are signatures stored?
No. Draw or upload a signature in this session, place it, and download. We do not keep a copy.
Will comments work in Adobe Reader?
Exports are a flattened PDF with drawn text, highlights, and images — not Adobe comment markup.
