PNG to JPG Converter
PNG files store every pixel losslessly, which is excellent for screenshots and logos but produces large files for photographs. Converting to JPG applies lossy compression that typically cuts the file size by 70–90% with no visible difference on photographic content.

How to convert PNG to JPG
- Drop your PNG file onto the upload area, or click it to choose a file from your device.
- Pick a quality level. 90% keeps the image visually identical to the original in most photos.
- Press “Convert to JPG” and wait a moment - the work happens on your own device.
- Compare the original and converted sizes, then press “Download JPG”.
Why convert PNG to JPG?
The most common reason is size. A photo saved as PNG can easily be 4–5 MB; the same photo as a quality-90 JPG is usually under 600 KB. That matters for page load times, email attachment limits and upload forms that cap files at 2 MB.
Compatibility is the second reason. JPG is accepted virtually everywhere - print services, marketplace listings, older CMS uploaders and document editors all handle it without complaint.
The trade-off is transparency. JPG has no alpha channel, so any transparent area has to be filled with a solid colour. This converter uses white, which is the right choice for most logos and product shots placed on a white page.

Frequently asked questions
Will converting PNG to JPG reduce the image quality?
JPG uses lossy compression, so some data is discarded. At the default 90% quality the difference is invisible on photographs. On sharp-edged content such as screenshots or text you may notice slight halos around edges, in which case keep the PNG or use WebP instead.
What happens to transparent areas?
JPG cannot store transparency, so transparent pixels are filled with white before the image is encoded. If you need to keep transparency, convert to WebP instead.
Are my images uploaded to a server?
No. The conversion uses the Canvas API in your browser. The file is read from your device, converted locally and offered back to you as a download. It is never sent anywhere.
Is there a file size limit?
There is no server limit because there is no server. In practice very large images (above roughly 50 MP) can exhaust the memory your browser tab is allowed to use, especially on older phones.
