To convert PNG to JPG, drop the PNG above, keep quality at 90% (or lower it for a smaller file) and download the JPG. For photos and photo-like screenshots the JPG is usually a fraction of the PNG size with no visible difference. Nothing is uploaded: the page loads the converter once, then the file is read and written by your own browser.
Why convert PNG to JPG?
PNG stores every pixel losslessly, which is ideal for logos and interface screenshots but wasteful for photographs: a phone photo saved as PNG is often several times larger than the same photo as a JPG. Some upload forms, older programs and print services also accept only JPG.
How it works
1. Drop a PNG into the converter (or tap to choose one on a phone).
2. JPG is already selected as the output. Move the quality slider if you want: 90% is the default; 80–85% saves more with little visible change on photos.
3. Check the before/after size shown, then download the JPG. The image is decoded and re-encoded with MozJPEG, the encoder behind Google’s Squoosh, compiled to run in your browser.
PNG vs JPG
PNG: lossless, supports transparency (alpha channel), best for text, line art, logos and UI screenshots, where JPG would blur edges.
JPG: lossy, no transparency, far smaller for photos and gradients, and accepted by practically every app, website and printer.
Rule of thumb: if the image is a photo, JPG; if it has sharp text, flat colours or a transparent background, stay with PNG (or use WebP, which does both).
Quality notes
JPG cannot store transparency, so transparent areas become solid. If your PNG is a logo on a transparent background, convert to WebP instead or keep the PNG. Sharp text can show faint ringing ("artefacts") at low quality settings — keep 90% or higher for screenshots with text. Converting only once avoids stacking losses.
Common use cases
Shrinking photos that were saved as PNG before emailing them; meeting a site’s “JPG only” upload rule; reducing the size of a folder of scanned photos; preparing images for printing services.
Frequently asked questions
What happens to a transparent background?＋
JPG has no alpha channel, so transparent pixels are written as solid colour. For a logo that must stay transparent use PNG to WebP instead.
Which quality setting should I use?＋
90% (the default) is visually identical to the PNG for photos. 80–85% gives a noticeably smaller file and is still fine for the web. Below about 70% blockiness starts to show.
Why is my JPG not much smaller?＋
Screenshots with large flat areas are already compressed well by PNG. JPG wins on photos; on flat graphics the gain is small and PNG often looks better.
Can I convert several PNGs at once?＋
This converter handles one image at a time. For a folder of PNGs, use the Batch Image Convert tool, which converts many files to JPG in one go.
Does it work on iPhone and Android?＋
Yes, in Safari or Chrome. The downloaded JPG goes to your Files or Downloads folder.
