PNG to JPG Converter

PNG is a lossless format built for graphics, transparency, and editing accuracy. JPG trades some of that precision for much smaller files — typically 3-10x smaller for photographic content. Converting PNG to JPG makes sense when file size matters more than pixel-perfect fidelity or when the destination (a platform, an email attachment limit, a print vendor) simply requires JPG.

PNG vs JPG: what actually changes

• Compression: JPG discards some data to shrink file size. At 90%+ quality, the loss is invisible to the eye; it becomes visible as blocky artifacts only at low quality settings.
• Transparency: JPG has no alpha channel. Any transparent areas in the source PNG get filled with a solid background color (white by default) — there's no way around this.
• File size: This is the whole point of converting — JPG output is dramatically smaller, which matters for email attachments, uploads with size limits, and page load speed.
• When not to convert: If the PNG has transparency you need to keep, or if you'll be re-editing the image repeatedly, stay in PNG (or move to WebP, which supports both transparency and strong compression).

How to convert PNG to JPG

1. Upload: Drag and drop your PNG files.
2. Set quality: 85-95% keeps quality loss invisible; go lower only if you specifically need a smaller file.
3. Convert: Runs locally via WebAssembly — nothing uploaded.
4. Download: Individually or as a ZIP.
