Frequently Asked Questions
Does converting to grayscale reduce total PDF file size?
Yes. Eliminating color channels and converting 24-bit color images to 8-bit grayscale significantly compresses file weight.
Are confidential business reports uploaded to external servers?
No. All color conversion algorithms execute 100% locally in your web browser. Your files never touch a cloud server.
Will colored pie charts and bar graphs still be easy to differentiate?
Yes. Luminance-weighted color conversion maps different color hues to distinct grayscale tonal values for clarity.
