Safety & privacy
Unlike our in-browser PDF tools, this AI feature sends your image to our AI server for the best possible quality. Your image is used only for your processing request and then deleted from the server — no long-term storage, no AI training, no third-party sharing.
Genuinely free — no limits
KitsyApp is 100% free — no signup, no daily limits, no watermarks. Processing quality is on par with paid tools like Smallpdf or iLovePDF, and your files are processed on your own device instead of someone else's server.
Frequently asked questions
Is my original image modified?
No. The original on your device is untouched; the enhanced result is a new file to download, so you can compare before and after.
How long does processing take?
Usually seconds to a few dozen seconds depending on image size and mode (2x is faster than Ultra HD). A progress bar shows the status.
Are processed images kept on the server?
No. Images exist only during processing and are then deleted. We do not store your images or use them to train AI models.
Which mode should I use for printing?
Pick Ultra HD for large prints, 4x for medium prints, 2x for screens and social media. The sharper the source, the better the result.
