Common Questions

No. Exports are generated as a new PDF and your original file is untouched.
Yes — the tool supports PDFs up to 100MB. Very large files may take longer to process depending on your device.
A “0” inserts a blank placeholder in the stitched grid — useful when the input PDF includes instruction pages or gaps in the layout.
If your PDF includes optional-content layers, the preview can toggle them. Some pattern PDFs don’t include layers, in which case all content is included.
Projector mode applies projector-friendly defaults and optional overlays. Some PDFs may embed content in ways that limit full per-path edits; use the preview and test squares to confirm results.
No. Processing runs locally in your browser.
