PaperLayer: a hidden text layer you can print on paper
PaperLayer reads and creates PDFs whose printed dot patterns carry recoverable text, with document processing done in the browser.
- For
- People creating or reading PaperLayer V5/V6 printed documents
- Worth noticing
- V6 leaves protective bands near folds, edges, and corners; the page says the embedded content is not encrypted.
Field notes
The creation flow takes an A4 portrait PDF and Markdown or plain text, then generates a printable file; the editor notes that tables, images, and HTML are handled in Markdown source rather than its visual controls. Reading can start from an uploaded file or a camera image, with corner marking available to align the page. The page specifies printing at actual size and says V6 adds protective bands near folds and edges. It identifies its reader as experimental and limits support to V5 and V6.
