What is an ERF file?
ERF – Epson RAW photo. ERF is a RAW photo format from Epson: the data straight from the camera's sensor, before it is turned into a JPG. It keeps more detail to adjust, but needs a RAW converter to be opened.
ERF Converter →What is a WEBP file?
WEBP – WebP image. WebP is a format from Google for the web. It makes pictures smaller than JPG or PNG, supports transparency and animation, and is read by every current browser.

Good to know
- Choose a quality in Options: lower numbers make a smaller WEBP with less detail.
- ERF files are developed on our server with the camera's own white balance, then saved as WEBP. Expect a good-looking picture, not a replacement for your RAW editor.
- Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.
Frequently asked questions
Is converting ERF to WEBP free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my ERF pictures uploaded anywhere?
This conversion runs on our server, because a browser can't develop camera RAW files. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion.
How large can the ERF file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Can I change the size or quality of the WEBP?
Yes. Click Options next to the file to set a width and height, choose a quality, remove metadata and more. Only the settings that make sense for ERF to WEBP are shown.
Can I convert several ERF files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
