A free file converter with 63 tools for images, PDF, Word, Excel, OCR and audio that runs 100% in your browser without uploading files to servers.
What it is
Konvizi is a free file converter offering 63 tools for converting and editing images, PDFs, Word documents, Excel files, text, CSV, JSON and audio files. Every conversion runs entirely in your browser using JavaScript and WebAssembly downloaded from konvizi.com, with files never uploaded to servers.
The service relies on open-source libraries including pdf.js, pdf-lib, Tesseract, lamejs and heic2any. Users can verify that no files are uploaded by opening their browser's developer tools and checking the Network tab during a conversion. The site enforces a Content-Security-Policy that prevents the browser from contacting any site other than konvizi.com.
Konvizi requires no sign-up, adds no watermark and imposes no maximum number of files. It works on computers, iPhones, iPads and Android devices in Chrome, Edge, Firefox or Safari. Speed and maximum file size depend on device memory, as processing occurs locally.

Questions from the bench
- How can I check that my files are not uploaded?
- Open your browser's developer tools using F12, go to the Network tab and run a conversion to verify that no request carries your file. The site enforces a Content-Security-Policy security rule 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.
- Why are some conversions not offered, such as Word to PDF or PDF to Word?
- A browser cannot yet perform these conversions with good enough quality, as all processing happens on your device with the limitations of browser technology.
- What happens to my files when I close the tab?
- Closing the tab erases everything the page held in memory, as no files are stored on servers or saved anywhere.
- Does it work on iPhone and Android?
- 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.
