How to use
- Add one or more PNG files — choose them, drag them in, or paste a screenshot.
- Adjust the quality if you want. 85 keeps photos visually identical; lower values give smaller files.
- Download each JPG, or all of them as a ZIP.
Options explained
- Quality
- JPG is lossy. 80–90 is visually lossless for photos; for screenshots with text, stay at 85 or above to keep lettering crisp.
- Transparency
- JPG cannot store transparency, so transparent pixels become white. If you need to keep a transparent background, convert to WebP or keep the PNG.
- Resize
- Optionally scale large images down while converting.

Frequently asked questions
Why convert PNG to JPG?
PNG stores every pixel exactly, which makes photos huge — a phone photo saved as PNG can be 10 MB or more. The same image as a quality-85 JPG is usually a fraction of that size and looks the same.
When should I keep PNG instead?
Keep PNG for logos, icons, diagrams and anything with transparency or sharp flat-colour edges, where JPG compression shows artefacts around lines and text.
Will the quality get worse?
Converting to JPG is lossy, but at quality 85 or higher the difference is rarely visible for photos. Convert from the original PNG, not from a JPG that has already been compressed.
Are my images uploaded?
No. The PNG is decoded by your browser and re-encoded with MozJPEG in WebAssembly, on your device.
