Why this free PNG to JPG converter runs in your browser
Most online converters upload your image to a server, convert it remotely, and send it back. That round trip takes time and puts your file on someone else's infrastructure. OnlyFiles skips all of that.
The conversion uses the Canvas API built into every modern browser. Your PNG is loaded into an invisible canvas element, rendered, and exported as a JPG. The entire process happens in JavaScript on your device. No network requests. No server contact. You can disconnect from the internet after loading this page and the converter still works.
How the free PNG to JPG conversion works
The browser's Canvas API loads your PNG image, including any transparency data. It draws the image onto a canvas element with a white background (since JPG does not support transparency). It then exports the canvas content as a JPG file at a 92% quality setting.
The result is a standard JPG file that works everywhere. The 92% quality setting preserves visual detail while reducing file size compared to the original PNG. For most images, the JPG will be 60 to 80% smaller than the PNG.
Transparency in the original PNG becomes a solid white background in the JPG output. If you need to preserve transparency, convert to WebP instead.
PNG vs JPG and when to convert
PNG is lossless and supports transparency. It is ideal for screenshots, text-heavy graphics, logos, and images where every pixel matters. The tradeoff is file size, as PNG files are significantly larger than JPG for photographic content.
JPG uses lossy compression that is optimized for photographs and complex images with gradients. It produces much smaller files but does not support transparency and introduces minor compression artifacts.
Convert PNG to JPG when you need a smaller file for uploading, emailing, or embedding in documents. Keep your original PNG for editing, archival, or when transparency is required.
Common questions about free PNG to JPG conversion
Does converting PNG to JPG reduce quality?
There is a small quality reduction because JPG uses lossy compression. At the 92% quality setting OnlyFiles uses, the difference is not visible for photographs and most graphics. Fine text and hard pixel edges may show very slight softening.
What happens to transparency when I convert PNG to JPG?
JPG does not support transparency. Transparent areas in your PNG become a solid white background in the JPG output.
How much smaller will the JPG file be?
For photographic images, the JPG is typically 60 to 80% smaller than the PNG. For simple graphics with solid colors, the reduction may be less dramatic.
