Will converting to black and white reduce my PDF's quality?

Text sharpness and page structure are fully preserved. Images and graphics convert to grayscale, which may simplify some visuals but never affects readability.

Is there a file size limit for conversion?

Free users can upload PDFs up to 50 MB. Larger files are supported under our premium plans, which also remove daily usage limits.

How long are my files stored on your servers?

All uploaded and converted files are automatically deleted within 24 hours. We do not use your documents for any other purpose.

Can I convert a password-protected PDF?

Password-protected PDFs must be unlocked first. Use the KolayDönüştür PDF Unlock tool to remove protection, then run the color conversion.

Does this work on mobile devices?

Yes. The tool runs entirely in your mobile browser on both iOS and Android without any app download needed.

Is the tool really free to use?

Yes, within the daily free-tier quota. For unlimited conversions and larger file support, affordable monthly plans are available.
