RAF is Fujifilm's RAW camera format with its distinctive X-Trans sensor data. That is why users land on this page looking for a AVIF copy. A RAF → AVIF operation is one of the simplest image jobs there is: same pixel grid, different wrapper. What genuinely changes is how lossy the codec is, whether alpha survives, and how large the final file ends up. KaijuConverter picks safe defaults for each of those and lets you override them under Advanced. Background. RAF is Fujifilm's RAW camera format with its distinctive X-Trans sensor data. Destination side, AVIF is the AV1-based next-gen image codec, extremely efficient with full HDR and alpha support.
Fujifilm RAW
Source formatRAF is the RAW image format used by Fujifilm cameras, containing unprocessed sensor data with Fujifilm color science.
AVIF Image
Target formatAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
Why convert RAF to AVIF
The real reason to move from RAF to AVIF is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking AVIF solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
RAF → AVIF
Provide the RAF
Click or drag to upload. We accept a single RAF file per job, with an optional queue of additional images for batch mode.
Encode to AVIF
The conversion decodes the RAF, resolves the colour space to sRGB and writes the AVIF container around the pixel data.
Save the AVIF
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all AVIF outputs is produced instead.
Common Use Cases
Document embeds
Word, Google Docs and Pages embed AVIF with correct aspect ratio; RAF may appear as a broken image icon.
Printer-friendly export
Consumer and office printers drive AVIF through their print spoolers with no additional drivers.
Presentation slides
PowerPoint and Keynote treat AVIF as a first-class citizen; RAF may need manual re-insertion per slide.
Online form uploads
Identity verification, job applications and legal forms often list AVIF as the only accepted image format.
Quality & Compatibility
RAF-to-AVIF conversion does not change the visible content. Quality is capped by the RAF decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original RAF alongside the AVIF copy.
Tips for Best Results
- Large RAF files may look identical to small AVIF files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export AVIF at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related RAF images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both RAF and AVIF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If AVIF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded RAF exactly, but cannot recover detail that RAF had already compressed away.
Often yes, especially when AVIF is lossless. RAF tuned for efficient web delivery will usually produce smaller files than AVIF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
