Compare the file sizes in the preview, then download the JPG.
PNG vs JPG: When to Use Each
PNG is the right format for graphics with sharp edges, text, logos, and transparency: screenshots, icons, charts, and UI elements. Its lossless compression keeps every pixel perfect. JPG is the right format for photographs and complex gradients, where its perceptual compression delivers dramatically smaller files with no visible difference at high quality settings. A common web performance mistake is serving photographic PNGs that are five to ten times larger than an equivalent JPG. Converting those to JPG at 80 to 85 percent quality is one of the highest-impact page speed wins available. On the other hand, converting a logo or screenshot to JPG introduces blurry artifacts around sharp edges, so keep those as PNG or WebP. Transparency is the deciding factor for the background fill: logos with transparent backgrounds need a chosen fill color when going to JPG, while full-bleed photos have no transparency and convert cleanly. When in doubt, compare the two previews and file sizes this tool shows before downloading.
Background Fill Tips
White is the universal default and matches documents, marketplaces, and most web pages. If the JPG will sit on a colored website section, sample that exact color for an invisible blend. For product photos on dark-themed sites, a dark fill looks far more premium than white. Avoid mid-gray fills for photos with soft shadows, since the shadow edges can show a faint halo against the fill color.
Frequently Asked Questions
Why does my PNG need a background when converting to JPG?
The JPG format does not support transparency. Any transparent pixels must become a solid color, and white is the standard choice for photos and documents. Without a fill, transparent areas would render as black in most converters. This tool lets you pick any background color instead.
What quality setting should I use?
90 percent is the sweet spot for most uses: visually identical to the original with a much smaller file. Use 95 to 100 for print or archival work, and 70 to 80 for web images where loading speed matters more than pixel perfection.
Will converting reduce the image dimensions?
No. Pixel dimensions stay exactly the same: a 2000 by 1500 PNG becomes a 2000 by 1500 JPG. Only the format and compression change. If you also need smaller dimensions, resize first with the social media image resizer tool and then convert, since converting first and resizing second is equally fine quality-wise.
Can I convert JPG back to PNG?
Yes, but it will not restore quality lost in JPG compression, and the file will be larger. PNG is lossless, so converting JPG to PNG just wraps the existing pixels in a bigger file. Convert from the highest quality source you have.
Is my image uploaded to a server?
No. Conversion runs entirely in your browser using the Canvas API. Your images never leave your device, which is faster than uploading and completely private. There are no file size limits imposed by a server and no queues during busy times.
Why is the JPG so much smaller than the PNG?
PNG uses lossless compression that preserves every pixel exactly, which is inefficient for photographs with millions of colors. JPG uses perceptual compression that discards detail the human eye barely notices, often shrinking photos to 10 to 20 percent of the PNG size.
