PNG to JPG Converter
Convert PNG images to JPG to cut file size sharply, especially for photos and screenshots with lots of color. It runs in your browser, so nothing is uploaded.
Your images never leave your device
How to use PNG to JPG
- Drop your PNG files on the page or pick them from your device.
- Wait while each file is converted to JPG on your device.
- Check any logo or screenshot: transparency becomes white and fine text can soften.
- Download the JPG files one by one, or all together as a zip.
Frequently asked questions
How much smaller will my JPG be?
For photographs, usually 70 to 90 percent smaller. For screenshots, diagrams and graphics with flat color the saving is smaller, and a PNG can even stay competitive. The result depends on how much fine detail the image contains.
What happens to a transparent background?
It turns white. JPG has no transparency, so the converter fills transparent pixels with white. If you need to keep transparency, convert to WebP, which is also much smaller than PNG.
Will text in a screenshot look worse as a JPG?
It can. JPG compression tends to smudge sharp edges, which shows up as faint noise around small text. For screenshots with a lot of text, PNG or WebP is a better choice.
Can I convert many PNG files at once?
Yes. Add as many as you like, and download each JPG separately or all of them as one zip file.
Are my PNG files uploaded anywhere?
No. The conversion runs in your browser using WebAssembly, so your PNG files stay on your device. There is no signup, no watermark and no cost, and you can convert a whole batch and download it as a zip.
About PNG to JPG
PNG is lossless, and that is exactly why PNG photos are huge. A phone photo exported as PNG can be 15 MB or more, which blows through email attachment limits, form upload caps and storage quotas. Converting to JPG typically shrinks a photographic PNG by 70 to 90 percent while looking nearly the same on screen. Many sites that ask for a profile photo, a document scan or a product picture set a limit of a megabyte or two, and JPG is how you get under it.

Screenshots are the exception worth knowing about. Text, thin lines and flat interface colors compress very well as PNG, and JPG can leave faint halos around them. If the image is mostly text, check the result at full size, or keep the PNG and use the PNG compressor instead.
JPG is lossy, so this conversion permanently discards some detail. At normal viewing size a photo looks the same, but you cannot get the lost detail back, so keep the PNG if it is an original. JPG cannot store transparency, so transparent areas are filled with white; a logo with a see-through background will come out on a white one. Metadata is removed, and any orientation flag is applied to the pixels.
PNG is lossless, so no detail is ever discarded; JPG is lossy, using discrete cosine transform compression. JPG cannot store transparency, so any transparent area in the PNG file turns white. For scale, a 12-megapixel photo is typically 15 to 25 MB as PNG and 2 to 5 MB as JPG. Compatibility: Every browser, phone, camera, editor, email client and upload form opens it, which is its main strength.
