PNG to JPG Converter

PNG is perfect for screenshots, logos and graphics with sharp edges, but it's a poor fit for photos. Because PNG is lossless, a photo saved as PNG can be five to ten times larger than the same photo as a JPG. Converting to JPG is the quickest way to shrink photo-like PNGs before emailing them, uploading them to a form with a size limit, or posting them online.

Common examples are photos edited in an app that exports PNG, scanned pages saved as PNG, and large screenshots of photos or video frames.

For photographic images, expect the JPG to be a fraction of the PNG's size: a 6 MB PNG photo often becomes 600 KB–1.5 MB at 90% quality. Graphics with large areas of flat colour, such as logos, diagrams and simple charts, compress well as PNG already, so converting them saves little and can make edges look slightly blurred.

To shrink files further, lower the quality to 70–80% or set a maximum width. Both settings apply to every image in the batch.

A good habit is to convert one image first, compare it with the original at full size, and then convert the rest with the same setting.

JPG compression can create faint smudges around sharp text and thin lines. For screenshots that are mostly text, keep the quality at 90% or higher, or consider keeping them as PNG and reducing their size with the PNG compressor instead. For screenshots that are mostly photos or video, JPG is a great choice.

JPG doesn't support transparency. Transparent areas are filled with the background colour you choose, white by default, which is usually what you want for documents and email. If the image will be placed over a coloured background on a website or in a design, choose that colour so the edges blend in, or keep the image as PNG.

Need the opposite? JPG to PNG converts the other way. For a deeper comparison, read PNG vs JPG.

Add a whole folder's worth of PNG files and they are all converted with the same quality, size and background settings. Download each JPG on its own or get everything in a single ZIP with the original file names kept. This is a quick way to shrink a folder of exported photos or screenshots before backing them up or sharing them.

The converter works the same on Windows, Mac, iPhone, iPad and Android. Photo metadata isn't carried over, so camera details and location data in the PNG aren't copied into the JPG, which also trims a little extra size.
