RAF to TIFF Converter

Convert RAF to TIFF: What This Tutorial Covers

This walks a Fujifilm shooter through turning a .RAF raw capture into a TIFF — the format print labs and editors expect for a high-fidelity working copy. The one setting that trips people up is the Compression Type, which defaults to JPEG (lossy); the steps below show how to get a genuinely lossless TIFF and what to do when the output looks off.

How to Convert RAF to TIFF

1. Upload Your RAF File: Drag and drop your Fujifilm .RAF files onto the page or click "+ Add Files" to browse. You can queue several at once and they convert with the same settings.
2. Set the Compression Type: Open Advanced Options and change "Compression Type" from its JPEG default to LZW or Deflate for a lossless TIFF; leave it on JPEG only if you specifically want a smaller, lossy file.
3. Set DPI and Resolution (Optional): Pick a DPI preset for print (300 DPI is the print-ready default) and either keep the original capture size under "Image resolution" or scale it down with "Preset Resolutions" or a Width/Height.
4. Convert and Download: Click "Convert" and save your TIFF. No sign-up, no watermark.

Walk-through: Choosing a Compression Type

TIFF is a container that can hold image data several different ways, and the choice decides whether your file stays lossless. On this page the "Compression Type" dropdown opens on JPEG, which is lossy — fine for a smaller proof, wrong for an archival or print master. Match the setting to the job:

• Want a true lossless master (archive, print, further editing): choose LZW or Deflate. Both shrink the file with zero quality loss, and the image can be edited and re-saved repeatedly without degrading. LZW has the broadest reader support; Deflate (ZIP) usually packs a bit smaller.
• Want the largest compatibility with old print RIPs and scanners: choose None (uncompressed). The file is big but every TIFF reader on earth opens it.
• Want a smaller TIFF and don't mind lossy: keep JPEG. Use this only when file size matters more than pixel-perfect fidelity.

If you just need a finished picture to share or post rather than an editable master, a TIFF is overkill — convert straight to JPG instead and skip the compression decision entirely.

Common Errors and How to Fix Them

• "My TIFF is lossy / lost quality" — the Compression Type was left on the JPEG default. Re-run with LZW or Deflate (or None) for a lossless result.
• "The file is enormous" — uncompressed TIFFs of a full-resolution Fuji capture run into tens of megabytes. Switch from None to LZW or Deflate to shrink it losslessly, or drop the DPI/resolution if you don't need full size.
• "The colors or look don't match my camera" — Fujifilm Film Simulations (Velvia, Classic Chrome, Acros) are render-time instructions, not pixels stored in the RAF, so a neutral render won't reproduce them. Apply the look in a RAF-aware editor first, then convert the exported image.
• "My browser won't preview the TIFF" — that's expected. Outside Safari, browsers don't display TIFF natively (MDN); open it in an image editor or photo viewer instead.
• "Won't upload" — confirm the file is a Fujifilm .RAF and not an already-converted JPEG, and that the upload finished, since raw files are large and take longer to send.

When This Doesn't Work

This converter renders the raw file once and bakes in the current white balance, exposure, and tone, so the TIFF carries no more editing latitude than any finished image — demosaicing and the baked render discard the recovery headroom RAW holds. If you still need to push shadows, highlights, or white balance, do that in a RAW developer (Lightroom, Capture One, RawTherapee, or Fujifilm's own tools) and export the TIFF from there. Keep the original .RAF as your master either way. For a web-ready delivery copy rather than an editing master, RAF to AVIF or RAF to JPG is the better target. The same conversion is available as RAF to TIF — .tif and .tiff are the same format, just a different extension.

Frequently Asked Questions

Why is my RAF to TIFF output lossy when TIFF is supposed to be lossless?

Because the "Compression Type" dropdown defaults to JPEG, which is a lossy scheme TIFF is allowed to use. TIFF itself is a container that supports several compression methods — for a lossless file pick LZW, Deflate, or None instead. With any of those the image can be edited and re-saved without losing quality, which is the whole reason to choose TIFF over JPG.

Should I pick LZW or Deflate for a lossless TIFF?

Both are lossless and both are good defaults. LZW is the older, most universally readable TIFF compression, so choose it if an old print RIP or scanner has to open the file. Deflate (ZIP compression) typically produces a slightly smaller file and is well supported in modern software. If a tool refuses to open a Deflate TIFF, re-export as LZW.

Is 300 DPI the right setting for sending a TIFF to a print lab?

The DPI tag tells a printer how large to lay the pixels down; it doesn't change the pixel data itself. 300 DPI is the standard for photo prints and the default here, so most labs accept the file as-is. For oversized prints viewed from a distance you can go lower, and some fine-art reproduction labs ask for more — check your lab's spec sheet, but 300 DPI is the safe default for a RAF rendered at full resolution.

Do I keep my RAW editing latitude after converting RAF to TIFF?

No. A RAF holds unprocessed sensor data, which is why exposure, white balance, and highlight recovery stay adjustable while it's raw. Converting renders the photo — demosaicing the sensor data and baking in the current settings — so the TIFF is a finished image. It's a high-fidelity finished image (lossless if you choose LZW or Deflate), but the recovery headroom is gone. Keep the original .RAF if you might re-edit.

Does this handle X-Trans files from Fujifilm X-series cameras?

Yes. Most Fujifilm X-series bodies use the X-Trans color filter array — a 6×6 pattern instead of the usual Bayer grid — and the converter demosaics it into a standard TIFF. RAF files from GFX medium-format and some entry-level Fujifilm models, which use a conventional Bayer sensor, convert the same way.

Why does the TIFF look different from the preview on my Fujifilm camera?

The in-camera preview applies a Film Simulation (Velvia, Astia, Classic Chrome, Acros and so on) that isn't stored as pixels in the RAF — it's a render-time instruction. A faithful, neutral render of the raw data won't reproduce that look. To match the camera, apply your film simulation or edit in a RAF-aware developer, export the finished frame, and convert that.

How large a RAF can I upload, and how is my file handled?

In our testing, a full-resolution Fujifilm RAF saved as an LZW TIFF stayed close to the size of the original raw file, since lossless compression preserves all the detail. Your file is uploaded over an encrypted connection, rendered and encoded to TIFF on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The practical limit is upload size and time, not your device, since raw files often run tens of megabytes each.
