Is my file uploaded to a server?
No. Every other online converter uploads your file to a server. Lokafile never uploads anything — the work happens in your browser, so your file physically never leaves your device.
Do I need to sign up or pay?
No account, no payment, no watermark, no CAPTCHA before download. Free.
Does it work offline?
Yes — once loaded, you can disconnect and it still works. You can even install Lokafile as an app.
Is there a file size limit?
No artificial cap. The only limit is your device’s memory.
How do I avoid stretching the image?
Keep “Lock ratio” on — height follows width automatically so proportions stay intact.
Does resizing reduce quality?
Downsizing keeps images sharp. Enlarging beyond the original size can look soft, since pixels are being invented.
