HOW TO CONVERT ARW → TIFF
Provide the ARW
Click or drag to upload. We accept a single ARW file per job, with an optional queue of additional images for batch mode.
Encode to TIFF
The conversion decodes the ARW, resolves the colour space to sRGB and writes the TIFF container around the pixel data.
Save the TIFF
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all TIFF outputs is produced instead.
Situation. ARW is Sony's RAW photo format for Alpha cameras. Solution: a TIFF, produced below. A ARW → TIFF 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. Technical note: ARW is Sony's RAW photo format for Alpha cameras. Compare that with TIFF is the archival multi-page master format used in scanning, print and document pipelines.
Why convert ARW to TIFF
The real reason to move from ARW to TIFF 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 TIFF solves those edge cases at the cost of a short conversion step.

ARW vs TIFF — Strengths and limitations
What each format does best, and where it falls short.
ARW Strengths
- Full 14-bit sensor data on flagship bodies.
- Rich Sony metadata (Creative Style, DRO, Focus Magnifier).
- Supported by every major raw processor.
- Lossless compression available on modern bodies.
Limitations
- Proprietary — new Sony body launch = Lightroom update required.
- Lossy compression was the only option on many older bodies (visible banding in highlights).
- File sizes are huge on 50+ MP bodies.
TIFF Strengths
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitations
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
Quality & Compatibility
ARW-to-TIFF conversion does not change the visible content. Quality is capped by the ARW decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original ARW alongside the TIFF copy.
Tips for Best Results
- Large ARW files may look identical to small TIFF files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export TIFF at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related ARW images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both ARW and TIFF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If TIFF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded ARW exactly, but cannot recover detail that ARW had already compressed away.
Often yes, especially when TIFF is lossless. ARW tuned for efficient web delivery will usually produce smaller files than TIFF'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.
Sony RAW ARW

TIFF Image
Target formatTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Common Use Cases
Share across platforms
Send TIFF files to anyone without worrying about whether they have the right software for ARW.
Embed in documents
Drop TIFF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TIFF often produces smaller files than ARW for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
