Konvizi
Free No upload
Images, PDF, Word, Excel and text files converted right in your browser. Nothing leaves your device.
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.
Most online converters start by uploading your files to their servers. Konvizi works differently: the conversion is done by your own browser, on your computer or phone. Your photos, scans and documents never pass through a server.
The result: no waiting for an upload, no imposed size limit, and no reason to worry about a personal document. Choose a conversion above, drop your files, and collect the result.

Yes. Every conversion is free, with no sign-up, no watermark and no maximum number of files.
No. The conversion happens entirely in your browser. Your files stay on your device and we never have access to them.
Images in HEIC, JPG, PNG, WebP, AVIF, SVG, BMP, GIF and ICO, with compression and resizing; PDF (images to PDF, PDF to images, merge, split, compress, rotate, delete and reorder pages, extract, page numbers, watermark, edit, sign, protect and unlock); text documents (TXT, PDF, Word .docx); and data: Excel (.xlsx), CSV and JSON; text recognition (OCR) for images and scanned PDFs; and audio: MP4 to MP3, WAV, M4A, OGG and FLAC to MP3, MP3 to WAV, and cutting audio files.
No. Konvizi runs in any recent browser (Chrome, Edge, Firefox, Safari), on a computer or a phone, with nothing to install.
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.
