Pick a PDF
Up to 50 MB. The file never leaves your browser — all processing happens locally.
Different use case — for slides, social posts, or sending pages individually. Not an "anti-copy" feature; the PDF mode options above are ignored when this is checked.
Advanced options
2 ≈ 144 DPI (good default). 3 for print quality. Above 3 makes huge files for little gain.
0.85 is a balanced default. 0.6 is much smaller but visibly compressed. ZIP mode always uses lossless PNG.
✓ Done — file downloaded

Honestly: what this does and doesn't do
No marketing copy. Read this before you rely on it for anything that actually matters.
Flatten-to-image PDF — the truth
WHAT IT DOES
- Stops normal readers from selecting/copying text in Adobe Reader, Preview, Chrome, etc. — the text layer is genuinely gone.
- Adds friction. Most people who want to copy a few lines will give up rather than reach for OCR.
- Preserves the original visual layout exactly (it's a snapshot of each page).
- Keeps everything local — your file never touches our servers.
- Works for forms with sensitive prefilled values you don't want exported as text.
- Locked mode: mainstream PDF readers (Adobe, Preview, Chrome) gray out their print, copy, and edit buttons. Most users who see that simply give up and stop trying.
WHAT IT DOES NOT DO
- It's not encryption. The PDF is fully readable by anyone who opens it.
- OCR (Adobe, Tesseract, ChatGPT vision, etc.) recovers the text in seconds.
- Screenshots and screen recording are impossible to prevent in a browser.
- File size usually grows (vector text → JPEGs); accessibility, search, links, and forms are lost.
- Locked mode: the permission flag is a soft hint to PDF readers.
qpdf --decrypt, Acrobat, or any free online unlocker removes it in seconds. It will not stop anyone determined. - For real access control — expiring links, view counts, revocation — use the encrypted-share flow on the home page instead.
