Why use our studio?
Powerful, private, and precise.
Your files stay on your device
Pages are rendered and merged in your browser. Nothing is uploaded, nothing is stored, and closing the tab clears it all.
Visual page manager
See a thumbnail of every page, drag to reorder, rotate, duplicate or delete before you export.
Live watermark editor
Position text and image watermarks, page numbers, headers and footers on a real preview of the page.
Password protection
Lock the merged file with a password (RC4 128-bit). Keeps casual readers out — treat it as a deterrent, not strong encryption.
Blank page detection
Scans for near-empty pages and marks them in the grid, so you can see exactly what will be left out before you export.
True redaction
Blackout boxes are burned into the page, not drawn on top of it — the text underneath is removed, not just hidden. Redacted pages are flattened to an image.
