How to use this tool
Upload your PNG files
Drop one or many PNG files onto the upload area. PNG files with transparency are fully supported - transparent areas will be filled with white in the JPG output.
Choose a quality level
Higher quality means larger files and more detail. 90% (our default) is barely distinguishable from 100% and saves significant space. For web thumbnails, 70–80% is often perfectly fine.
Convert and download
Click Convert to start. Your browser encodes each PNG to JPG using a WebAssembly JPEG codec. Download individually or all at once as a ZIP.
Compare file sizes
Each downloaded file shows the size reduction percentage. A typical screenshot at 80% quality shrinks by 60–80% versus the original PNG.
Frequently Asked Questions
What happens to PNG transparency when converting to JPG?
JPG doesn't support transparency. Any transparent or semi-transparent pixels in your PNG are composited over a white background before encoding. This is the standard approach used by image editors like Photoshop. If you need to preserve transparency, convert to WebP or keep the PNG format.
How much smaller will the JPG be compared to the PNG?
It depends heavily on the image content. Screenshots and images with large flat color areas often compress extremely well - a 5 MB PNG screenshot might become a 200 KB JPG at 85% quality. Photos with complex textures typically see 70–85% size reduction.
Is there a lossless way to convert PNG to a smaller format?
Yes - try our PNG to WebP converter. WebP's lossless mode typically reduces PNG file size by 25–35% without any quality loss. For the smallest lossy files, PNG to AVIF offers the best compression ratio.
Why is my PNG with text looking blurry after converting to JPG?
JPEG compression introduces artefacts (ringing and blurriness) around high-contrast edges like text. For images with crisp text or sharp lines, use a quality setting of 90–95% or consider staying in PNG format. Screenshots of text are almost always better kept as PNG.
Can I batch convert hundreds of PNG files?
You can drop up to 20 files at once, and they'll all convert in parallel. For larger batches, repeat the process. Each session resets - previously converted files are cleared when you click "Convert more files."
