File Formats

Autoenhance supports a wide range of standard, high-quality, and RAW file formats to suit your needs. On this page, you can see a list of the files we support, along with an overview of which to pick for your use case.

hashtag
Standard Quality Images

Standard-quality images are the most common type due to their small file sizes and high compatibility, but they aren't designed for modern photographers' needs.

Autoenhance currently supports the following commonly used file formats:

  • JPEG (Joint Photographic Experts Group)

  • WEBP (Web Picture format)

hashtag
Pros

  • Small file size, which makes them fast to upload to and process with Autoenhance.

  • Widely supported and can be edited without any compatibility issues.

hashtag
Cons

  • Formats like JPEG use Lossy Compression to reduce image quality by discarding some data. Repeated saving can further degrade the image.

  • Images have a restricted range of brightness levels, which can result in loss of detail in very bright or very dark areas.

hashtag
High Quality Images

High-quality images are an increasingly popular image format that balances compatibility with quality, allowing images to display the full range of colours on modern displays in a way that is easy to share.

Autoenhance currently supports the following commonly used file formats:

  • AVIF (AV1 Image File Format)

  • HEIC (High Efficiency Image Coding)

  • TIFF (Tagged Image File Format)

hashtag
Pros

  • Images can capture and display a wider range of brightness levels, preserving details in both highlights and shadows.

  • With higher bit depths, images display more accurate, vibrant colours, improving overall image quality.

  • With the exception of TIFFs, their small file sizes make them fast to upload and process with Autoenhance.

  • Enjoys good support and can be edited without any compatibility issues.

hashtag
Cons

  • Not many cameras export to these formats directly, so usually a conversion step is required using software like Adobe Lightroom before uploading to Autoenhance.

  • Doesn't contain all the data recorded by the camera, so there are still limitations on how the image can be edited compared to RAW.

hashtag
Raw Quality Images

Raw-quality images focus on capturing the data as the camera captures it, allowing full flexibility during the editing process. This comes at the cost of compatibility and file size.

Note on Incompatible Files:

If you are having issues with your specific RAW format (such as the new Nikon HE* High Efficiency compression found in newer Z-series cameras such as the Z9, Z8, Zf, and Z6 III) we recommend exporting these to JPG in a tool like Lightroom. We are looking to add support as soon as possible.

⚠️ Known Issue: Sony Lossless Compressed. We are currently working on full support for Sony Lossless Compressed (L) RAW files. At this time, these files may process with a visible border that requires manual cropping after downloading.

  • Recommended Workaround: For the best results without manual editing, please set your Sony camera to Uncompressed or standard Compressed (Not "Lossless Compressed").

Autoenhance currently supports the following RAW file formats:

  • Adobe Digital Negative (.dng) - Version 1.4 or lower only.

    • Warning: DNGs saved in "Express" format may cause processing errors. Additionally, DNGs relying on "Stage 3" operations may not render visually as expected.

    • Recommendation: When using Adobe DNG Converter, set compatibility to "Camera Raw 7.1 and later" (DNG 1.4).

  • Apple ProRaw (.dng)

  • Canon (.cr2, .cr3)

  • DJI Drone (.dng)

  • Fujifilm (.raf)

  • Hasselblad (.3fr, .fff)

  • Leica (.rwl, .dng)

  • Nikon (.nef, .nrw) — Excluding HE/HE formats*

  • Olympus / OM System (.orf)

  • Panasonic (.rw2)

  • Pentax (.pef)

  • Sigma (.x3f)

  • Sony (.arw, .srf, .sr2)

  • Tagged Image File Format (.tiff)

hashtag
Pros

  • Access to the original data captured by the camera gives Autoenhance the flexibility to create the best possible enhancement.

  • Support for a wider range of professional camera manufacturers.

hashtag
Cons

  • Most file formats are proprietary and undocumented. While we update frequently, this can occasionally lead to compatibility issues when a manufacturer launches a new model with a novel compression format.

  • The flexibility of the editing process means the output in different programs can look different from what you might expect.

  • File sizes can grow very large, slowing Autoenhance uploads.
