Converting RAW to TIFF, explained
This pipeline extracts the full-resolution preview embedded in your RAW files and re-encodes it as TIFF — the lossless interchange format that print shops, archives and editing suites accept without complaint. The TIFF encoding happens in-browser too, so the whole RAW→TIFF trip never touches a server.
The same honesty as the JPG sibling applies: this preserves the camera's rendering losslessly from here onward; it doesn't reprocess sensor data. For tonal editing headroom, develop the RAW in dedicated software — for a lossless copy of what the camera saw, this is the two-click route.
Where a RAW-to-TIFF handoff fits, and where it doesn't
Intake systems are the reason this page exists: print labs, stock agencies, university repositories and court exhibit rules that accept TIFF and refuse JPG and RAW alike. What you get is the camera's own rendering of the shot, wrapped in a container that will never lose another bit no matter how many times it is opened and re-saved. What you do not get is a 16-bit linear file with RAW editing headroom — this is an 8-bit sRGB image derived from the embedded preview, with the camera's white balance and picture style baked in. For that headroom, export a 16-bit TIFF from Lightroom, Capture One, darktable or RawTherapee instead.
Mechanically, the preview JPEG is decoded to pixels on a canvas and written out as uncompressed RGBA TIFF: no ICC profile, no EXIF, and the orientation exactly as the camera stored the preview, which may be sideways for portrait frames — the Rotate Image tool fixes that in one pass. Each conversion holds the full uncompressed image in browser memory, so queue a handful of files at a time rather than a whole card. Output names keep the RAW's base name with a .tif extension. If an 8-bit TIFF at this size is more than the recipient needs, RAW to JPG delivers the identical pixels at roughly a twentieth of the bytes.

Frequently asked questions
Everything you need to know about the RAW to TIFF.
01Why is my TIFF sideways, and how do I fix it?
Because the preview is written exactly as the camera stored it, and no EXIF orientation tag is carried into the TIFF, so a portrait frame can open on its side. Run the file through the Rotate Image tool: the rotation is applied to the pixels and re-saved, which every viewer then honours. Keep the RAW file, which remains the only editable copy.
02Why convert RAW to TIFF instead of JPG?
Pipeline requirements: print workflows, archival standards and some editors specify TIFF. The conversion is lossless from the preview onward — no further generation loss no matter how many times the TIFF is re-saved. The cost is size: TIFFs run many times larger than JPGs.
03How large will the TIFF be, and is it compressed?
Uncompressed, 8-bit RGBA at four bytes per pixel: a 24-megapixel preview (6000×4000) becomes a 96 MB TIFF, and a 45-megapixel one about 180 MB. The in-browser TIFF writer applies no LZW or ZIP compression, so treat the result as a handoff file — open it in Photoshop, Affinity or GIMP and re-save with LZW once if you need to archive it. Convert a few files at a time rather than a whole card, both for download size and for browser memory.
