Frequently Asked Questions
Can I edit existing text in a PDF?
Yes. TetraKits detects text on each page so you can click and edit it directly. For scanned PDFs (image-only pages), use Add text box to place new text on top.
Are my files uploaded to a server?
No. PDF editing happens entirely in your browser. Your files are never sent to our servers.
Does it work on mobile?
Yes. The editor is responsive — tap text to edit, use the toolbar to add text or change size and color, and swipe through page thumbnails.
Is this tool free?
Yes. TetraKits PDF Editor is completely free with no signup, subscriptions, or usage limits.
