Why Convert PNG to JPG?
PNG files are excellent for graphics and screenshots, but they create unnecessarily large files when used for photographs. Converting PNG photos to JPG typically reduces file size by 60–80% while maintaining visual quality that is virtually indistinguishable from the original. This makes images faster to upload, easier to share by email, and lighter on storage.
JPG uses lossy compression optimized for photographic content. Colors blend naturally and fine details are preserved at quality settings above 80. If your image has no transparency and is not a screenshot or line art, JPG is almost always the better choice for file size.
With LeanImg, your images never leave your device — conversion happens entirely in your browser. There is no server upload, no waiting for a round trip, and no privacy risk. Drop your files and download the result in seconds.
After converting, compress your JPG to squeeze out even more savings. Working with modern formats? Try PNG to WebP for the best of both worlds.

Frequently Asked Questions
How to convert PNG to JPG?
Open LeanImg in any browser, drop your PNG files into the converter, and download the JPG versions instantly. The entire process is free, requires no sign-up, and works without uploading your images to any server. You can convert multiple PNG files at once.

Yes. LeanImg processes images entirely in your browser using WebAssembly. Your files are never uploaded to a server, never stored anywhere, and never seen by anyone else. Close the tab and the data is gone. It is as private as editing files on your own computer.

Does converting PNG to JPG reduce quality?
JPG uses lossy compression, so there is a small quality reduction. At the default quality of 85, the difference is nearly invisible to the human eye. For photos, this tradeoff is worth it because file sizes drop by 60–80%. You can adjust the quality slider for finer control.
Will I lose transparency when converting PNG to JPG?
Yes. JPG does not support transparency. Any transparent areas in your PNG will be filled with a white background. If you need to keep transparency, convert to WebP or AVIF instead, which support both transparency and smaller file sizes.
