Click inside the file drop area to upload your ERF file or drag & drop it.

Choose your desired format based on your needs—different formats suit different purposes, like JPEG for smaller file sizes. The conversion process typically takes a few seconds, depending on file size and server load.

Q: Can I convert an image to PDF?
A: Yes! You can easily convert images to PDF. Just upload your image, select the PDF format, and your image will be part of a clean, easy-to-share PDF document.
Q: What is image conversion?
A: Image conversion is the process of changing an image from one format to another, like converting a PNG to a JPG. This can help you reduce file size, improve quality, or ensure compatibility with different devices and platforms.
Q: Can I convert a photo to a transparent PNG?
A: Yes, you can convert a photo to a transparent PNG as long as it has a transparent background to begin with. If it doesn’t, you’ll need to remove the background before converting it to PNG to preserve transparency.
Q: Can I convert a photo to black and white?
A: You can definitely convert a photo to black and white, although this feature isn’t built into the conversion process itself. Consider using image editing software to adjust the colors before uploading for conversion. Many apps also have filters that can turn your image black and white!
Q: What’s the best way to maintain image quality during conversion?
A: To preserve image quality, select a lossless format like PNG or TIFF for conversions. Avoid formats that compress images too much, like JPEG, if high quality is your priority.
What is ERF (Epson Raw Format)?
ERF (Epson Raw Format) is the proprietary raw image format used by Epson digital cameras. Like other raw formats, it contains minimally processed data directly from the camera's image sensor.
ERF files preserve the maximum amount of information captured by the camera, including wider dynamic range and color information compared to processed formats like JPEG.
Photographers prefer working with ERF files for high-quality photo editing as they offer greater flexibility for adjusting exposure, white balance, and other parameters without quality degradation.
These files are larger than processed image formats because they contain the uncompressed or lightly compressed raw sensor data along with camera metadata.
How to open ERF?
ERF files can be opened with Epson's proprietary software that comes with their digital cameras, such as Epson Photo Lab or Epson Raw File Converter.
Professional photo editing software like Adobe Photoshop and Adobe Lightroom have native support for opening and processing ERF files.
Other popular photo editing applications such as Capture One, DxO PhotoLab, and Corel AfterShot Pro also support the ERF format.
For free alternatives, RawTherapee and darktable are open-source programs that can process ERF files with advanced editing capabilities.
ERF is Developed by: Epson Corporation
ERF was Released on: Early 2000s
