No. Everything runs in your browser - your file never leaves your device. How this is verifiable
PNG files are often needlessly large for photos. JPG cuts the file size substantially and is ideal for photos, email attachments and websites - with barely any visible difference.
The image is painted onto a local canvas and exported as JPG; transparency is filled with white. Nothing is uploaded.
JPG uses lossy compression that deliberately removes image detail the human eye barely notices - which often shrinks photo files to a fraction of the PNG size. For a holiday photo that is ideal; for a line drawing or a screenshot with text it is not, because JPG creates visible halos around sharp edges. You set the right trade-off between size and sharpness with the quality slider.

Limitations: JPG is lossy and stores no transparency (transparent areas become white). For graphics with sharp edges, PNG remains better. Embedded metadata such as capture date, camera and GPS location does not survive the re-encode - only the image orientation is baked into the pixels beforehand.
For photos often 60-80% smaller, depending on the quality setting.
Yes. JPG has no alpha channel, so every transparent area is filled with a solid colour. White is the preset, but the Background option lets you choose a different fill colour, for example so a logo matches the background it will sit on later.
No, everything runs locally in the browser.
For photos, 0.8 to 0.9 is a good compromise between file size and sharpness. Only below that do the typical block artefacts at edges become clearly visible.
Yes, download individually or as a ZIP.
No, it is free and unlimited - no account, no watermark, no daily quota. Local processing in the browser is what makes that possible.
Yes - in the mobile browser the conversion works just like on a computer, with no app at all. A Chromebook or tablet is enough too.
