Can I edit existing text in a PDF directly online for free?

Yes! GoPDF extracts text layer bounding boxes using pdfjs-dist and overlays interactive editable blocks. You can click on any text to modify words, change font colors, delete unwanted sentences, or add brand-new text blocks directly in your browser.

How does GoPDF match the original font and styling?

Our intelligent fontMatcher engine analyzes raw font metrics, weights, and styles (Serif, Sans-serif, Monospace, Bold, Italic) extracted from the PDF, automatically mapping them to the closest standard PDF typography (Helvetica, Times Roman, Courier).

Are my documents uploaded to external servers?

Never. The entire editing, whiteout redaction, and re-stamping process runs 100% locally in your device's RAM memory using WebAssembly. Your files never leave your computer.

How do I save and export my edited PDF?

When you're finished making edits, click 'Export & Download PDF'. GoPDF executes an in-memory redaction pass to white out modified regions and stamps your new text in place, downloading a crisp, updated PDF file instantly.
