What changes
JPG and PNG side by side: quality, size and where each one opens.
JPG/JPEG vs PNG

PNG keeps more detail than JPG/JPEG. PNG opens on every major platform. Convert JPG/JPEG files when the app, site or workflow you use needs PNG.
How it works
- Step 1:
Drop the JPG file on the orange block above, or press “Choose JPG”.
- Step 2:
Press “Convert to PNG”. The block shows the progress while the server converts the file.
- Step 3:
Press “Download” to save the PNG file. On Free the link works for 24 hours.
How JPG to PNG conversion works
Converting a JPG (JPEG) image to PNG format changes the file from a lossy-compressed raster image to a lossless-compressed one. JPEG uses Discrete Cosine Transform compression, which permanently discards fine detail to reduce file size. That suits photographs, not images where every pixel must stay exact. PNG uses DEFLATE lossless compression, meaning every pixel is preserved exactly as encoded. This makes PNG the preferred format for screenshots, diagrams, logos, and any image that contains sharp lines or flat areas of colour. The PNG output from a JPG-to-PNG conversion will be pixel-identical to the source JPEG, but the file size will typically be larger because lossless encoding retains all pixel data and no further compression artefacts are introduced. 1converter performs this conversion using ImageMagick, preserving ICC colour profiles, transparency channels (if applicable), and metadata such as EXIF orientation tags.
Sources and specifications
Quality levels for JPG → PNG
| 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 PNG file is good for and why people convert to it.
- No further lossPNG keeps the pixels exactly; artefacts already in the JPG stay
- Transparency supportAdd alpha channel
- Graphics with text or logos
- Images needing transparency
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The PNG 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
