Shrink PNG files by converting them to JPG
PNG files are lossless, which makes them big — often megabytes for a single screenshot. Converting to JPG typically cuts the file size by 80–90%, which is why upload forms, email attachments, and websites usually prefer it. This converter does the job entirely in your browser: no upload, no queue, no account.
Drop in as many PNGs as you like. Each is re-encoded as a high-quality JPG on your device and ready to download in seconds.

Frequently asked questions
Are my images uploaded to a server?
No. Your browser converts each PNG to JPG locally. Nothing is transmitted anywhere.
How much smaller will my files get?
For photos and screenshots, JPG is typically 5–10× smaller than PNG. Simple graphics with few colors compress less dramatically but still shrink substantially.
What happens to transparent areas?
JPG doesn't support transparency, so transparent regions are filled with white. If you need to keep transparency, stay with PNG or use WebP.
Does converting reduce quality?
JPG is a lossy format, but at the 92% quality setting used here the difference is invisible for photos. Text-heavy screenshots may show slight softening — zoom in to check if it matters for your use.
