Step-by-Step Guide
5 steps · takes under 1 minute
Open the Convert to JPG tool
Go to the Convert to JPG tool — it runs in your browser with no upload and no account required.
Upload your PNG
Drag and drop your PNG file. The tool accepts PNG, WebP, GIF, and BMP as input.
Choose background for transparency
If your PNG has a transparent background, JPG cannot store transparency. The tool fills the transparent areas with white by default — ideal for most use cases. For product photos, white is correct.
Set quality (85% recommended)
Higher quality preserves more detail. For web use, 80–85% produces files that are visually indistinguishable from lossless PNG while being 60–80% smaller.
Download your JPG
Click download. Your converted JPG saves directly to your device. The original PNG is untouched.
100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Always keep your original file before converting. Lossy formats like JPG discard data permanently — you can't restore quality that was compressed away.
