Change Text Color
Upload a PDF, pick a target text color, tune darkness sensitivity, and export a recolored document while preserving page order and dimensions.
Higher values recolor more dark regions.
Important note
This method recolors dark pixels, so non-text dark graphics can also be affected. It works best on text-focused documents.

About Change Text Color
What this tool does
Change Text Color updates dark text-like content in PDF pages to your selected target color while keeping the original page order.
How it works
Each page is rendered as an image, dark pixels are detected by threshold, and matched pixels are replaced before rebuilding the final PDF.
Threshold behavior
Lower thresholds target only very dark text, while higher thresholds include a wider range of dark content for stronger recoloring.
Output expectations
The output keeps visual page structure, but pages are rebuilt from rendered content to apply color changes consistently.
Privacy and security
Conversion runs in your browser session and does not require external server processing.
Best-fit documents
This tool works best for text-focused PDFs. Image-heavy pages may show broader color changes in dark regions.
