PNG vs JPG
PNG keeps sharp edges and transparency — great for logos and screenshots but larger. JPG compression is ideal for photos and much smaller. If your image is a photo, JPG is almost always the right delivery format.

PNG vs JPG: Which Format Should You Actually Use? →Questions people ask
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.
What happens to transparent areas?
JPG doesn’t support transparency, so transparent pixels are filled with the color you pick — white by default.
How much smaller will my file be?
For photos, typically 60–80% smaller at 85–90% quality with no visible difference.
