Why ConvertKoro

Common questions
More detail in the full FAQ.
Is ConvertKoro really free?
Yes. Every tool is free to use, with no limit on file count and no watermark added to your output.
Do you store or see my files?
For most tools, no — processing happens locally in your browser and we never receive your files. Two tools work differently by necessity: Image-to-Text sends the image to a cloud OCR service by default (an on-device option is available), and the URL Shortener stores the link you submit so it can redirect visitors. Both are disclosed on the tool itself and in our Privacy Policy.
Do I need to install anything?
No installation needed — everything runs in a normal browser tab on desktop or mobile.
