How JPEG to HDR conversion works
The JPEG Image format uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. Converting to HDR produces a document file that stores data in the HDR format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. This makes HDR the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
Sources and specifications
Quality levels for JPEG → HDR
| 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 HDR file is good for and why people convert to it.
- Expands dynamic range for brighter highlights and deeper shadows compared with standard JPEG tone mapping
- Produces HDR metadata/encoding for compatible HDR displays to render stronger contrast
- Converting camera JPEGs for HDR viewing on HDR-capable phones and TVs
- Preparing JPEG-based stills for HDR thumbnails and presentations in HDR pipelines
Where your file goes
- It travels to our server over an encrypted HTTPS connection and is converted there.
- The HDR 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
