Frequently asked questions
How do I invert PDF colors online?
Drop the PDF into this tool, preview the inverted pages, then download. Conversion runs in your browser — free.
Is this the same as grayscale?
No. Invert flips colors (a negative). Grayscale removes color into shades of gray or high-contrast black.
Will I still be able to select text?
No. Each page becomes an image, so text is not selectable in the downloaded PDF.
Are my files uploaded?
No. Color invert on ConvertPeach runs entirely in your browser.
