Frequently Asked Questions
How do I convert a PNG to JPG?
Upload your PNG file (or files) to our converter, choose the JPG quality (92% is good for most photos), and click 'Convert to JPG'. The conversion happens in your browser and you can download the result immediately. No software installation or sign-up required.
What happens to transparency when converting PNG to JPG?
JPG does not support transparency, so any transparent pixels in your PNG will be filled with the background color you choose. The default is white (#ffffff), which works well for most photos and screenshots. You can pick any color using the color picker before converting.
Will I lose quality when converting PNG to JPG?
JPG uses lossy compression, which means some quality is lost during conversion — unlike PNG which is lossless. However, at 92% quality, the visual difference is nearly imperceptible for photos, and the file size is typically 50-80% smaller. For archival or print work where quality is critical, keep the quality at 92% or higher. For web/email use, 70-80% quality is usually sufficient.
How much smaller is JPG vs PNG?
JPG files are typically 50-80% smaller than PNG files for photographic content. For example, a 1MB PNG photo might become a 200-400KB JPG at 92% quality. PNG is more efficient than JPG only for images with sharp edges, large areas of solid color, or transparency (like logos, screenshots, and icons) — in those cases, keeping the PNG format is recommended.
Can I convert multiple PNGs to JPG at once?
Yes! Our converter supports batch conversion. Just drag multiple PNG files into the upload area (or click to select multiple), choose your quality and background color, and click 'Convert to JPG'. All files are processed in parallel and you can download them individually or all at once.
Is it safe to convert PNG to JPG online?
Our converter is safer than most online tools because everything happens in your browser — your images are never uploaded to a server. The HTML5 Canvas API does the conversion locally on your device. This makes it ideal for personal photos, confidential documents, or any image you don't want shared with a third-party service.
When should I use PNG vs JPG?
Use PNG for: screenshots, logos, icons, line art, images with transparency, and any image where quality is critical. Use JPG for: photos, complex images with gradients, web images where file size matters, email attachments, and social media uploads. A good rule of thumb: if the image has fewer than 256 colors or contains text, use PNG; otherwise use JPG.
Can I convert JPG back to PNG?
Yes, you can use our free JPG to PNG converter for the reverse direction. Note that converting JPG to PNG will not restore any quality lost in the original JPG-to-JPG conversion — the lossy compression artifacts will be preserved. Use PNG as your final format only if the source was already lossless.
