Convert PNG to JPG
Convert PNG images to JPG format with adjustable quality and dramatically smaller file sizes. PNG files are lossless and often 3-10x larger than necessary for photographs and web images. Converting to JPG reduces file size by 50-80% while maintaining visual quality that's virtually indistinguishable from the original. Compresso processes everything in your browser — your images are never uploaded to any server.

When to Convert PNG to JPG
PNG and JPG serve different purposes. PNG excels at graphics with sharp edges, text, transparency, and flat colors. JPG excels at photographs and complex images with gradients and many colors. Converting from PNG to JPG makes sense when:
- The image is a photograph that was saved as PNG unnecessarily — screenshots of photos, camera exports defaulting to PNG, or images downloaded from websites in PNG format
- File size is a concern — PNG photos are dramatically larger than necessary for web, email, and social media use
- A website or form requires JPG format — some upload portals specifically accept only JPG/JPEG files
- You're optimizing web performance — every extra KB slows down page loads, and PNG photos waste bandwidth
When NOT to Convert
Keep your images in PNG format when:
- You need transparency — JPG has no alpha channel; consider PNG to WebP instead
- The image has sharp text or UI elements — JPG compression creates visible artifacts around hard edges
- It's a logo or icon with few colors — PNG may actually be smaller than JPG for simple graphics
- You need pixel-perfect accuracy — for archival, medical, or scientific images
File Size Comparison
To give you a sense of the savings, here's what typical conversion results look like:
- Photograph (2000×1500): PNG ~8MB → JPG at 80% ~600KB (92% smaller)
- Screenshot with some photos: PNG ~3MB → JPG at 80% ~400KB (87% smaller)
- Complex illustration: PNG ~2MB → JPG at 85% ~300KB (85% smaller)
- Simple graphic with few colors: PNG ~50KB → JPG at 80% ~80KB (actually larger — keep as PNG)

Frequently Asked Questions
Why convert PNG to JPG?
PNG files are lossless and support transparency, but this comes at a significant file size cost. A photograph saved as PNG might be 5-15MB, while the same image as JPG at 80% quality could be 500KB-1MB — a 90% reduction with virtually no visible quality difference. Converting to JPG is essential for web performance, email attachments, and any context where file size matters.
Does converting PNG to JPG lose quality?
JPG uses lossy compression, so there is technically some quality reduction. However, at 80-90% quality settings, the difference is virtually invisible to the human eye for photographs and complex images. The only case where you'd notice is images with sharp text or geometric patterns — for those, consider keeping PNG or converting to WebP instead.
What happens to transparency when converting PNG to JPG?
JPG doesn't support transparency. Any transparent areas in your PNG will be replaced with a white background during conversion. If you need to preserve transparency while reducing file size, consider converting to WebP instead — WebP supports transparency with much smaller file sizes than PNG.
What quality setting should I use for PNG to JPG conversion?
For web images and social media: 75-80%. For email attachments: 70-80%. For high-quality prints or archival: 90-95%. For thumbnails and previews: 60-70%. The key insight is that most of the file size savings happen between 100% and 85% — going below 70% saves relatively less while quality drops become noticeable.
Can I convert multiple PNGs to JPG at once?
Yes! Compresso supports batch conversion. Upload multiple PNG files simultaneously, set your desired quality level, and all files are converted to JPG with the same settings. Download individually or grab all converted files as a single ZIP archive.
Is PNG to JPG conversion free?
Yes, completely free with no limits on file count, file size, or daily usage. No account or sign-up required. Compresso runs everything in your browser using client-side JavaScript.
Are my images uploaded anywhere during conversion?
No. All conversion processing happens entirely on your device in your browser. Your PNG files are read into browser memory, converted to JPG locally, and the output files are saved directly to your device. No network requests are made — your images never leave your computer.
Should I convert PNG to JPG or WebP?
For maximum compatibility (email, social media, older software): choose JPG. For web use where you control the platform: choose WebP — it produces 25-35% smaller files than JPG at equivalent quality. If you need transparency: WebP is the only option (JPG doesn't support transparency). For most web scenarios today, WebP is the better choice.
