FAQ
What color modes are available?
Grayscale (classic B&W), Sepia (warm vintage), High Contrast (pure B&W threshold), Invert (negative colors), Lighten (fade), and Custom Tint (your color overlay on grayscale).
What does the intensity slider do?
It controls how strongly the effect is applied. At 0% you get the original colors, at 100% the full effect. Anything in between blends the two — great for subtle adjustments.
Can I apply different effects to different pages?
Use the page range selector to choose specific pages. Run the tool multiple times with different ranges and effects, then merge the results using our Merge tool.
Is this processed on a server?
No. Everything runs 100% in your browser. Your PDF never leaves your device.
