JPG to PNG Converter FAQ

Is my file uploaded to a server?
No. All conversion happens in your browser using the Canvas API. Your files never leave your device.

Why is the PNG file larger than the original JPG?
PNG is lossless — it stores every pixel without compression artefacts. JPG achieves smaller sizes by discarding some image data. The larger PNG size means your image is now stored at full fidelity with no further quality loss.

Will there be any quality loss?
The conversion itself adds no quality loss. However, any compression artefacts already present in the original JPG will be preserved in the PNG — they don't improve by converting to PNG.

Will transparency be added to the PNG?
No. JPG images contain no transparency data. The converted PNG will have an opaque white background matching the original. If you need transparency, you'll need to remove the background separately.

Can I convert multiple JPG files at once?
Yes. Drop multiple files and download all converted PNGs in a single click.

When should I convert JPG to PNG?
Convert to PNG when you need to: edit the image further without quality degradation, use it in design tools that work better with PNG, add it to a transparent canvas, or deliver it to a service requiring PNG format.

Is PNG always better than JPG?
No. PNG is better for screenshots, logos, text, and images you plan to edit. JPG is better for photographs being shared or displayed online — it achieves much smaller file sizes at acceptable quality.

What is the maximum file size?
The tool handles very large JPG files. Processing speed depends on your device's capability — modern computers handle most images in under a second.

Can I use this tool on mobile?
Yes. The tool works on any modern mobile browser — iPhone Safari, Chrome for Android, and others.

Can I convert PNG back to JPG?
Yes. Use our PNG to JPG converter tool for that direction.

Background

Convert JPG images to lossless PNG format directly in your browser — no upload, no signup, no software installation required. PNG stores every pixel without lossy compression, so no additional quality is lost in the conversion (though any artefacts already present in the JPEG will be preserved).

Converting JPG to PNG is useful when you need to edit an image further without accumulating lossy compression artefacts, add it to a transparent background in design software, or use it in a context that requires PNG format. Note that the output PNG will be larger than the source JPG — this is expected. JPG achieves smaller sizes through lossy compression; PNG stores data losslessly.

Batch conversion is fully supported — drop multiple JPG files at once and download all PNGs in a single click. All processing runs client-side using the Canvas API; your files never leave your device.
