ERF
ERF is the camera RAW format of Epson digital cameras, such as the R-D1 rangefinder. It stores unprocessed sensor data for later adjustment. Software support for ERF is limited, so the files are usually converted to JPG, PNG, or TIFF.

PS
PS (PostScript) is a page description language developed by Adobe for printing. A PostScript file describes text, vector graphics, and images on each page and is used by printers and publishing tools. Few viewers open PS directly, so it is often converted to PDF, PNG, or JPG.
What happens when ERF becomes PS
Source format
ERF is the image source or target format for this conversion path.
Target format
PS is the image source or target format for this conversion path.
What changes
The ERF pixels are decoded and written using PS compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when PS supports them.
- Codec and quality implications
- Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a ERF file no larger than 1 GB.
- Confirm that PS is selected as the target.
- Download the PS file and check the result before deleting your source.
Troubleshooting
- The ERF file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The PS file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
