Konvizi’s “Edit PDF” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your PDF file into the area above or click “Choose files”. Its pages appear on your screen.
Click “Add text”, type, then drag the text where you want it. The A− and A+ buttons change its size.
Click “Download PDF”: your text is written into the document, on your device.
Many PDF forms cannot be filled in on screen: you would have to print them, write by hand and scan them again. Here you place your text directly on the page (a name, a date, an “X” in a checkbox, a short note) and download the completed PDF. The rest of the document is left untouched.
PDF is the universal document format: it looks the same on every device, keeps its layout and prints without surprises.
Contracts, payslips, bank statements, tax returns: PDFs often hold sensitive information. With Konvizi they never leave your device, are stored nowhere and read by nobody. Most PDF tools copy pages without recompressing them: selectable text, links and quality are preserved.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, and no maximum number of files.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
No. Konvizi adds text and signatures on top of the pages, but does not change the original text. To correct it, go back to the source document (Word, for example) and export it to PDF again.
The text is written in black in the Noto Sans font, from 6 to 96 points. Accented letters and the Devanagari script (Hindi) are supported; other scripts and emoji are replaced with “?”.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
