JPG / JPEG files only — processed in your browser.
How it works
The converter decodes your JPG, draws it onto an HTML5 canvas, then re-encodes the canvas as PNG. PNG is lossless, so the visual quality is identical to the source — but the file will be larger.
Examples
- A 1 MB JPG of a landscape usually becomes 4–8 MB as PNG.
- A JPG logo with a solid background converts cleanly to PNG.
- Use PNG only if you need lossless quality or transparency downstream.
Frequently asked questions
No. The conversion happens in your browser using the HTML5 Canvas API. The image never leaves your device.
Almost always yes. JPG is a lossy format designed for photos; PNG is lossless. For photographic images, expect the PNG to be several times larger. The benefit of PNG is lossless quality and optional transparency.
JPG does not support transparency, so there is no transparency to preserve. The PNG will be fully opaque. If you need transparency, you already have it — keep the original PNG instead.
Common reasons: making a logo lossless for further editing, removing JPG artifacts before more processing, or producing a file that supports an alpha channel for downstream tools.
