All files are processed on secure servers with encryption and automatically deleted immediately after processing. Your documents are never stored, shared, or accessed by anyone.

Frequently Asked Questions

Common questions about replacing text in PDF files.

Will the replacement text look exactly like the original?

Setpdf preserves the original font size, color, and position. The replacement text is inserted at the same location with matching formatting. In most cases, the original font is accurately matched. If the exact font cannot be identified, a visually similar font will be used to ensure the text displays correctly without garbled characters.

Yes! You can define multiple find-replace rules and apply them all in a single operation. Each rule is applied across all pages of the PDF simultaneously.

This tool works with text-based PDFs where the text layer is present. Scanned PDFs that contain only images require OCR processing first.

The replacement text is placed at the original text's starting position with the same font size. If it's longer, it may extend beyond the original boundary. For best results, use replacement text of similar length.

Unlike manual editing where you change text one by one, Setpdf lets you define multiple find-replace rules and apply them across all pages in one click. A 200-page contract that would take hours to update manually can be done in seconds — with consistent formatting preserved throughout.

Absolutely. All files are processed on our secure servers and automatically deleted immediately after processing. We never store, share, or access your document content.
