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.
Sources and specifications
Quality levels for PNG → JPEG
| Level | File size | Speed |
|---|---|---|
| Low qualitySmallest file, basic quality | Very small | Very fast |
| Medium qualityRecommendedBalanced size and quality | Medium | Fast |
| High qualityLarger file, great quality | Large | Moderate |
| Maximum qualityLargest file, best possible quality | Very large | Slow |
Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.
When to convert
What the JPEG file is good for and why people convert to it.
- Smaller file size than PNG, especially for photographic images
- Better compatibility with apps and web galleries that optimize for JPEG
- Upload screenshots/photos where JPEG is preferred or required by a site
- Share PNG images via email or messaging apps with size limits
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The JPEG file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.
- Want the file to stay on your device? Private Mode converts images right in the browser. Open Private Mode
