How to convert PNG to JPG
PNG stores image data losslessly, which makes it accurate but produces large files, especially for photographs. A full-resolution photo from a modern camera can be 10 to 30 MB as PNG. The equivalent JPEG at quality 85 is typically 1 to 4 MB, looking nearly identical to the naked eye in most viewing conditions. Converting PNG to JPG makes sense when you need a smaller file for sharing, uploading, or web use, and the image does not require transparency or exact pixel preservation.
This converter processes the PNG locally in your browser using WebAssembly. Nothing is uploaded to a server. You choose the JPEG quality level before converting, and the output file is ready to download immediately. The conversion is a single-step process with no registration, size limits, or watermarks.
Upload the PNG
Drop your .png file onto the converter. Large PNG files (10+ MB) are handled locally and are not limited by a server upload size cap.
Set JPEG quality
Choose a quality level between 1 and 100. Quality 85 is a solid default for photographs. Quality 70 to 75 is fine for web thumbnails. Quality 95 and above retains nearly all visual detail at a significantly larger file size than 85.
Convert in browser
The PNG pixel data is decoded and encoded as JPEG using the quality setting you chose. JPEG uses DCT-based compression that divides the image into 8x8 blocks, which is why very low quality settings produce a blocky appearance.
Download the JPG
Download the resulting JPEG file. Transparent areas in the PNG will be filled with white, since JPEG does not support transparency.
Frequently asked questions
Does converting PNG to JPEG cause quality loss?
Yes. JPEG is a lossy format. Information is discarded during encoding, and the loss is permanent. At quality 85 or above, the difference is not visible under normal viewing conditions, but it is not identical to the original PNG at the pixel level.
What happens to transparent pixels in the PNG?
JPEG has no alpha channel. All transparent areas are composited onto a white background before encoding. If you need transparency preserved, use WebP (which supports transparency and is lossy) or keep the PNG.
Is the PNG uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly. Your file never leaves your device.
Why is my JPG file larger than expected?
If the quality setting is very high (95 to 100), JPEG files can sometimes be larger than the source PNG for simple images with few colors or large solid areas. In that case, lower the quality or keep the PNG.
Should I convert my PNG logo to JPEG?
Usually not. Logos typically have sharp edges, solid colors, and text, all of which JPEG handles poorly. The block compression artifacts are most visible on these elements. Keep logos as PNG or SVG.
