About the JPG to PNG
JPG and PNG are the two most common web image formats and they work differently. JPG uses lossy compression, which keeps photographs small but can show blocky artefacts around sharp edges. PNG uses lossless compression and supports transparency, making it better for logos, screenshots, diagrams and text.
Converting a JPG to PNG does not restore detail the JPG compression already removed, so the image will not look better, and the file will usually be larger. The reasons to convert are to get a lossless copy to edit without further degradation, to meet a form that requires PNG, or to add transparency in an editor afterwards.
The conversion runs in your browser, so your picture stays on your device.
A 300 KB JPG photo may become a 2 MB PNG after conversion, because PNG stores every pixel exactly rather than approximating it.
Tips for best results
- If file size matters more than perfect fidelity, keep the photo as JPG or consider WebP.
- Do not repeatedly convert back and forth between formats; each lossy save loses quality.
