Does the text stay selectable and searchable?

Yes. The tool rewrites only the color instructions inside each text block — the glyphs, fonts and text objects are untouched, so copying, searching and screen readers all keep working.

Can I change only one color, like the blue headings?

Yes. Choose 'Only text matching a color', pick the source shade, and only text drawn in that color is rewritten. RGB, grayscale and CMYK color settings are all matched.

Will it recolor text in a scanned PDF?

No. A scan is an image — there are no text color operators to rewrite. Use an image-level tool like Adjust Colors or Invert Colors for scanned pages.

What about colored images or graphics?

They are left alone. Only color operators inside text blocks (between BT and ET) are rewritten, plus the inherited color a text block picks up from just before it.

My PDF is password-protected. Can I recolor it?

You can preview it after unlocking, but an encrypted file can't be edited in place. Run it through the Unprotect PDF tool first, then recolor the result.

Can I check the result before downloading?

Yes. The preview shows the current page before and after the recolor side by side, so you can confirm the source color matched what you expected.

Are my files uploaded anywhere?

No. The content stream is decoded and rewritten locally in your browser. The document never leaves your device.

About Change Text Color

Recolor the Text, Keep Everything Else

PDF text color lives in the page's content stream: each text block sets a fill color with an operator like rg before drawing its glyphs. This tool rewrites those operators — inside text blocks only — so the words change color while fonts, sizes, spacing, images and vector graphics stay exactly as they were.

Because the text itself is never re-rendered, the result is still a real text PDF: searchable, selectable, and accessible to screen readers. That makes it the right fix when a document prints with unreadably light gray text, when a brand color needs updating across a report, or when colored headings need to come down to black for a print run.

What You Can Control

Two choices decide the whole job: which text to touch, and what color it becomes.

All Text or One Color

Recolor every text run in the document, or restrict the rewrite to text whose current color matches a source color you pick.

Exact Source Matching

The source picker reads RGB, grayscale and CMYK color operators, so 'only the blue headings' really means only the blue headings.

Before/After Preview

A side-by-side page preview shows the original and the recolored result before you commit, so a wrong source color never reaches the download.

Text Stays Text

Only color operators change — the file remains fully searchable and selectable, and fonts are untouched.

When to Use It — and When Not To

Use it for legibility fixes (light-gray body text to black), brand updates (old accent color to the new one), and print prep (colored text flattened to a single ink). It works on any PDF whose text is stored as text — which is most PDFs exported from Word, InDesign, LaTeX or a browser.

It will not recolor text that was flattened into an image — a scanned page or a screenshot has no text operators to rewrite. For those, an image-level tool like Adjust Colors or Invert Colors is the right job. Encrypted PDFs need unlocking first, since the content stream can't be edited while the file is protected.

How It Compares

Recoloring text operators is surgical; rasterizing or re-exporting is not.

Your Document Never Leaves the Device

The recolor happens entirely in your browser: the content streams are decoded, the color operators are rewritten, and the PDF is saved locally. Nothing is uploaded, and closing the tab wipes the data — which matters when the document is a contract, a manuscript, or anything else you wouldn't email to a stranger.
