Upload your PNG file, adjust the JPG quality slider (60–100%), preview the converted image with file size comparison, and tap Download. The entire conversion happens in your browser — your image never leaves your device.

No. JPG images do not contain transparency data. Converting JPG to PNG preserves the exact same image — it changes the container format but does not add transparency. To make a background transparent, you need a background removal tool.

PNG is a lossless format, so the image won’t lose quality when edited and re-saved. PNG also supports transparency and is preferred for graphics, logos, screenshots, and images with text or sharp edges. Converting to PNG is useful when you need to further edit an image without additional quality degradation.

Yes. This tool works directly in Safari and other mobile browsers on iPhone and iPad. After conversion, long-press the image and tap “Save to Photos” to download. No app required.

Yes. Your images are processed locally in your browser using the Canvas API. No files are uploaded to any server, no data is stored, and no one can access your images. It’s completely private.

This tool currently converts one image at a time. Batch JPG to PNG conversion is coming soon.
