Convert PNG to JPG
Free, private and fast: everything runs in your browser and your PNG files are never uploaded.
PNG to JPG: why convert
PNG is great for screenshots and graphics, but a photo or a detailed screenshot saved as PNG can be many megabytes, too large for an email attachment or for an upload form that insists on JPG anyway. JPG compresses photos far better, at a small, adjustable cost in quality. Add your PNG files, pick a quality and get JPG images back, one file or a zip for a batch. JPG has no transparency, so any transparent parts of the PNG are filled with white, the way a printed page would show them. The file list shows the size before and after, so you can see what you saved. Everything happens in your browser, so screenshots with personal details never leave your device.
How to convert PNG to JPG
- Drop your .png images in the box, or click to choose them.
- Pick a JPG quality. 90 % is a good default; 70 % gives the smallest files.
- Click Convert to JPG and download the image, or a zip with all of them.
What changes when you convert
Transparent areas become white
JPG cannot store transparency, so every transparent pixel is filled with white, and partly transparent edges are blended with white. A logo with a transparent background therefore gets a white box around it. That looks fine on a white page but shows as a white rectangle on a coloured one; keep the PNG for logos and icons that sit on other backgrounds.
Text and sharp lines
JPG is designed for photos. Around text, thin lines and flat colours it can create faint smudges and halos, which are most visible at low quality. For screenshots of documents or code choose 95 %, or keep the PNG if the text must stay perfectly crisp.
Quality and file size
The quality setting controls how much detail the JPG compression may discard. 90 % is hard to tell apart from the original; 80 % and 70 % make the file much smaller and are usually fine for photos on the web. The list shows each file's size before and after converting.
Simple graphics may not shrink
A diagram or icon with a few flat colours is often already small as PNG and can even grow as JPG. The big savings come from photos and detailed screenshots.
Convert from the original
Every time a JPG is edited and saved again it loses a little more detail. Keep your PNG as the master copy and make a fresh JPG from it whenever you need one.
About the formats
PNG
PNG (Portable Network Graphics) is a lossless image format from 1996 and the usual format for screenshots, logos, diagrams and images with transparency. Every pixel is stored exactly, so text and sharp edges stay crisp.
- Lossless: saving again never reduces quality.
- Supports full transparency (an alpha channel).
- Photos saved as PNG are usually several times larger than as JPG.
JPG
JPG (or JPEG) is the most widely used image format for photos, supported by every camera, phone, browser and image editor. It uses lossy compression, which keeps files small at a small cost in quality.
- Best for photos; text and sharp lines can get blurry edges.
- No transparency: transparent areas become a solid colour.
- The quality setting trades file size against detail.
Frequently asked questions
Are my images uploaded?
No. The PNG is read and the JPG is written by your own browser. Nothing is sent to a server, so screenshots with names, emails or account numbers stay private.
Can I get a black or coloured background instead of white?
This converter always uses white, which is what most people expect from a JPG of a logo or a document. For another colour, put the image on that background in an image editor first.
How much smaller will my files be?
It depends on the image. Photos and screenshots with gradients usually shrink a lot, while simple graphics shrink little or not at all. The file list shows the exact size of every JPG after converting, so you can try another quality setting and compare.
Is PNG to JPG conversion lossless?
No. JPG compression always throws away some detail, which is why the files get smaller. At 90 % or 95 % the difference is very hard to see in photos.
