What Happens to Your File When You Use KuickKonvert
KuickKonvert converts files on our server, not in your browser. Here is, step by step, where your file goes, how long it exists there, and how it is deleted.
Where your file is converted
When you press Convert, your file is uploaded to our server and converted there. The server is run by our hosting provider, Render, in its Singapore (Southeast Asia) region, and traffic reaches it through Cloudflare's network. If you are outside Singapore, this means your file is briefly processed in another country.
Each conversion gets its own temporary folder
Every conversion starts with a new, empty folder with a random name. Your uploaded file, any working files the converter creates and the converted result are all written into that folder. The helper programs we use, such as LibreOffice and Ghostscript, are pointed at the same folder for their own temporary files.
Each conversion also runs in a separate process with its own memory allowance and a time limit, so one very large file can't hold up the whole server.
When your file is deleted
When the conversion finishes, the converted file is read into memory, the whole folder is deleted, and only then is the result sent to your browser. If the conversion fails, the folder is deleted in the same way. The code that deletes it runs whatever the outcome, success or error.
If a server process stops unexpectedly in the middle of a conversion, its folder can be left behind. A clean-up removes any such folder once it is more than 30 minutes old. It runs whenever a server process starts, and at most every 30 minutes when a new conversion begins.
Size limits
Each upload can be up to 50 MB, counting all the files in it together. The image converters (HEIC, WEBP and PNG to JPG, and JPG to PNG) take up to 20 images at a time.
What our logs record
Our own application logs record which tool was used and technical error details when a conversion fails. They never contain file contents, and they are designed to leave out file names, although a report of an unexpected error may occasionally include one. Our hosting providers also see basic request details, such as the page or tool requested, as described in our Privacy notice.
What this means for you
Keep your original file: we don't keep a copy, so once the folder is deleted there is nothing we can send you again. Download the result when it is ready, and open it to check it before you rely on it. If a file contains information you are not allowed to share, don't upload it. Our Privacy notice has the full details.
