About Our Free PNG to JPG Converter
Our PNG to JPG converter turns PNG images into smaller JPG files right in your browser. Add one image or thirty, adjust the quality if you like, and download each result or the whole batch as a ZIP file. Nothing gets uploaded, so your images never leave your device.
The main reason people convert PNG to JPG is file size. A PNG photo can be several megabytes, which is too big for many upload forms, email attachments, and slow web pages. A JPG version of the same picture is usually far smaller and looks almost identical on screen.
PNG vs JPG: Which Format Should You Use?
PNG is a lossless format. It keeps every pixel exactly as it is and supports transparent backgrounds, which makes it ideal for logos, icons, and screenshots. JPG, also written JPEG, is a lossy format. It shrinks a picture by discarding fine detail the eye rarely notices, which makes it the better choice for photos.
To read more about how each format works, see the Wikipedia pages on the PNG format and the JPEG format.
When Should You Convert PNG to JPG?
A PNG to JPG conversion is a smart move in these cases:
- A website or form has a file size limit and your PNG is too large.
- You want faster page loading and your images are photos, not graphics.
- You are sending pictures by email or messaging apps and want smaller attachments.
- A platform, printer, or app only accepts JPG files.
Keep the PNG instead if the image has sharp text, a logo, or transparent areas you still need. JPG can blur thin lines and cannot keep transparency.
What Happens to Transparent Backgrounds in PNG to JPG?
JPG has no way to store transparency, so every transparent pixel needs a solid color. This PNG to JPG converter fills those areas with the background color you choose. The default is white, which suits most documents and web pages. If your page or design uses another color, change it with the color box and the preview updates for every image.
How Does the JPG Quality Setting Work?
The quality slider controls how much detail the JPG keeps. A higher number gives a sharper image and a bigger file. A lower number gives a smaller file but can add blur or blocky spots, especially around text and sharp edges. The default of 90 is a good starting point for photos. For screenshots with small text, try 95 or higher.
Remember that JPG compression is permanent. Keep your original PNG files, and avoid converting a JPG again and again, since each save can lower the quality a little more.
How This PNG to JPG Converter Protects Your Privacy
The conversion runs inside your browser using the built-in canvas feature. Your files are not sent to any server, which keeps private images private and makes the tool fast. The only extra file the page ever downloads is a small ZIP helper, and only when you click Download All with more than one image.
