How PNG to JPEG Conversion Works

Portable Network Graphics (PNG) uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. JPEG Image (JPEG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. This conversion changes the file's encoding, compression method, and supported feature set. Some pixel detail is discarded by the target's lossy encoder; quality is configurable via the compression setting. The result is a standard JPEG file readable by any compatible application. 1converter handles PNG-to-JPEG conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.

Frequently Asked Questions

Everything you need to know about converting PNG to JPEG

No. PNG is lossless, while JPEG uses lossy compression, so fine gradients and sharp edges may show artifacts at lower quality settings.
JPEG doesn’t support an alpha channel. Transparency from PNG is flattened into the selected background color, so fully transparent areas become opaque.
Often yes, especially for photos and images with smooth color variation. For simple graphics with few colors, PNG can sometimes be smaller.
JPEG is widely supported across browsers, image viewers, and most design tools. PNG is also common, but JPEG is more universally optimized for web delivery.
