Frequently asked questions

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 a lossless format — it stores every pixel without compression artefacts. JPG achieves smaller file sizes by discarding some image data. The larger PNG size is expected and means your image is now stored at full fidelity.
Will transparency be added to the PNG?
No. JPG images do not contain transparency information. The converted PNG will have the same opaque content as the original.
Is there any quality loss during conversion?
The conversion itself is lossless — no additional quality is lost. However, any artefacts already present in the original JPG will be preserved in the PNG.

Convert JPG images to PNG format without uploading your files to any server.

PNG is a lossless format, so the converted image preserves every pixel

without compression artefacts. The output file will typically be larger than

the original JPG — that is expected behaviour, as PNG trades file size for

perfect fidelity. All processing happens entirely in your browser using the

Canvas API, ensuring maximum privacy and speed.
