Grayscale changes page color and rasterizes the content. Compress PDF focuses on reducing file size and offers different compression modes. Choose according to whether color removal or size reduction is the main goal.

Frequently asked questions about PDF grayscale converter

Will searchable text remain selectable?

Because pages are rasterized, selectable text can be lost in the generated PDF.

Does grayscale always reduce file size?

No. Size depends on page content, scale, quality, and the original PDF structure.

How should I choose scale and quality?

Start with moderate values, inspect fine text and images, then adjust if clarity or file size is unsuitable.

Does the tool change my original file?

The tool creates a new result; the PDF you selected remains unchanged.

Can I use it with a password-protected PDF?

A protected PDF may need to be unlocked before the tool can read or process it.

Will large files take longer?

They can. Processing time depends on the file size, page count, and the work required for each page.
