RAF to HEIC Converter

RAF to HEIC or RAF to JPEG? The Short Answer

Most people converting a Fujifilm RAF reach for HEIC because they want an Apple-friendly file that is smaller than a JPEG. That is a reasonable goal, but the trade is not the one most pages describe. Convert to HEIC when the destination is Apple's Photos library and storage matters. Convert to JPG when the file has to open anywhere else, or when colour fidelity matters more than size — because at this site's default preset the JPEG actually keeps more colour resolution than the HEIC does.

Side-by-side: What Each Target Gives You From a RAF

The size advantage is real — HEVC intra coding is a far newer design than JPEG's — but how large it is depends entirely on the image and the preset, so treat any fixed "half the size" figure with suspicion.

When to Pick HEIC

• The photos are going into an iPhone, iPad or Mac Photos library and will mostly be viewed there.
• You are moving a large shoot onto a device where storage is tight and every file counts.
• The recipient is on Apple hardware and you have confirmed they do not need to forward the files onward.
• You want an intermediate that stays visually close to the render at a small size, and you still hold the .raf masters.

When to Pick JPEG Instead

• Anyone in the chain is on Windows, Android or a browser other than Safari.
• You are uploading to a website, a print lab, a stock library or a submission portal — almost none accept HEIC.
• Saturated or fine coloured detail matters: fabric, signage, foliage, coloured text. JPEG at the Very High preset keeps chroma at full resolution; HEIC does not, at any preset.
• You need the file to still be openable in ten years with no special software.

How to Convert RAF to HEIC

1. Upload Your RAF File: Drag your .raf files onto the page or click "+ Add Files". Only .raf inputs are accepted, and every queued file is converted separately with the same settings.
2. Pick a Quality Preset: Open Advanced Options and set Quality Preset. It ships on "Very High (Recommended)", which is the highest rung that does anything — see the table below.
3. Resize or Cap the Size (Optional): Under Image resolution keep the original dimensions, scale by percentage, or set Preset Resolutions / Width x Height. Switch to "Specific file size" if you need to land under a hard limit — note that Auto Scale is on by default there, which hides the manual resolution fields while it sizes the image for you.
4. Convert and Download: Click Convert and save the HEIC. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.

What the Quality Preset Changes on a HEIC

We encoded the same frame at every rung through the encoder this page uses. Two results are worth knowing before you touch the dropdown:

Comparing the Highest and Very High outputs of the same source gave an absolute pixel difference of zero and the same file size, so moving the dropdown up from the default buys nothing. If you want a better-looking file than the default, the lever is resolution, not the top preset.

Frequently Asked Questions

Will my HEIC keep the RAF's 14-bit colour depth?

No. HEIC as a format can store 10-bit and higher, but the raw decoder in this pipeline develops RAF at 8 bits per channel by default and the converter does not override it, so the pixels are already 8-bit before the HEIC encoder sees them. If you need more than 8 bits from a Fujifilm raw, use in-camera raw conversion to 16-bit TIFF or a desktop raw editor.

Is the "Highest" preset worth using over "Very High"?

No. We compared the two outputs from the same source: identical file size and an absolute pixel difference of zero. "High" (quality 90) is the first rung below the default that changes anything at all. Treat Very High as the ceiling on this page.

Why does my HEIC look slightly less crisp on coloured edges than a JPEG of the same photo?

Because of chroma subsampling. Our HEIC output is 4:2:0 at every preset — the two colour channels are stored at half resolution horizontally and vertically. Our JPEG output stays at 4:4:4 (full colour resolution) for the top three presets. On luminance detail HEIC generally wins; on saturated colour edges a Very High JPEG can look cleaner despite being larger.

Who can actually open a HEIC file I send them?

Apple platforms handle it natively in Photos, Preview and Quick Look. On the web, Safari 17 and later is the only major browser that renders HEIC, which caniuse currently puts at roughly 15% of users; Chrome, Firefox and Edge do not. Windows needs a codec extension installed, and support on Android varies by version and gallery app. If you are not certain about the recipient, send a JPEG.

What is the difference between the HEIC and HEIF output?

Only the filename. HEIC is Apple's name for a HEIF container carrying HEVC-coded image data, which is exactly what both pages produce — the bytes from RAF to HEIF and from this page are the same file under a different extension. Use .heic if the destination is Apple software, .heif if a tool specifically asks for it.

Why does the converted image look different from the camera's rear screen?

The rear preview is a camera-rendered JPEG with a Film Simulation and Fujifilm's own colour science applied. A general-purpose raw render produces a neutral baseline instead, and Fujifilm's X-Trans colour filter array — which is not the 2×2 Bayer grid most demosaic algorithms assume — means different converters resolve micro-detail slightly differently. Neither rendering is wrong; they are different interpretations of the same sensor data.

Does the HEIC keep my EXIF data?

Standard shooting metadata — camera body, lens, shutter, aperture, ISO, date — travels with the image. What does not survive is anything that only means something to a raw file: the un-demosaiced sensor data, the ability to change white balance non-destructively, and the option to re-render with a different Film Simulation later. Keep the .raf if any of that matters.

Can I convert a whole card of RAF files at once, and how are they handled?

Yes — queue as many .raf files as you like and each becomes its own HEIC with the settings you chose; nothing is merged. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public. If the results are still too large, run them through compress HEIC, and the RAF converter hub lists every other target this format can reach.
