Convert PNG to JPG for smaller files — typically 60–80% smaller for photographic content. Note: JPG has no alpha channel, so transparent PNG regions get flattened onto white.
The output uses the same production-grade encoder pipeline as our dedicated Convert to JPG tool: MozJPEG's trellis multipass for JPEG, oxipng at max effort for PNG, sharp-YUV libwebp for WebP, and SSIM-tuned libavif for AVIF. Files are optimized to be measurably smaller than what most online converters produce at the same quality setting.
Why convert PNG to JPG?
Convert PNG to JPG for smaller files — typically 60–80% smaller for photographic content. Note: JPG has no alpha channel, so transparent PNG regions get flattened onto white.
Common reasons to use JPG instead of PNG: Photos, product images, hero shots without transparency.
How the conversion works
Your PNG file is decoded in your browser using WebAssembly codecs (no upload, no server processing), then re-encoded as JPG using our production-grade encoder pipeline. The full round-trip typically completes in under a second per file on modern hardware. Nothing about your file is logged, cached, or transmitted anywhere.
Batch, privacy, and downloads
Drop up to 20 PNG files at once. Each file shows a preview, its before/after size, and a per-file download button. Hit "Download all" to get a single ZIP archive of all converted JPG files. Filenames preserve the original name and swap the extension automatically.
