How compression works
JPG compression drops detail the eye barely notices. Around 70–80% is the sweet spot: far smaller with no visible difference. The live preview here shows the exact output before you download, so there’s no guessing.
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.
Will compression make my image blurry?
At 70–80% quality, differences are invisible for most photos. Below 50% you may see blocky artifacts — the live preview shows exactly what you’ll get.
Why compress images at all?
Smaller images upload faster, fit email limits, and make websites load quicker.
