ERF is the RAW image format used by Epson digital cameras, containing unprocessed sensor data.
FITS (Flexible Image Transport System) is a standard format for astronomical data.
FreeFileConvert uses tuned encoding for ERF to FTS conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload ERF files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized FTS results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent FTS audio with dependable progress tracking.
ERF files preserve full sensor information for post-processing flexibility.
FITS files can contain multi-dimensional data, tables, and extensive metadata headers.
Upload your image file in the ERF format from your device, Dropbox, or Google Drive.
Select FTS as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
