When to Convert

Common scenarios where this conversion is useful

Sharing Sony photos without RAW software

Not everyone has Lightroom or Capture One. Converting your ARW files to TIFF lets anyone view and use your photos with standard image viewers and web browsers.

Professional print submission

Print labs and publishers typically require TIFF. Converting ARW to TIFF produces a print-ready file at full sensor resolution with no compression artifacts.

Long-term photo archival

TIFF is universally supported and will remain readable for decades. Converting ARW to TIFF creates a future-proof archival copy if you're concerned about long-term ARW format support.

Magazine and editorial submission

Editorial workflows often require TIFF format. Convert your ARW images to TIFF for submission to magazines, stock agencies, and editorial clients.

Frequently Asked Questions

Does converting ARW to TIFF lose quality?

Some quality reduction is inherent when converting from RAW to any standard format. RAW files contain 12-14 bits of color data per channel, while TIFF uses 8 bits. However, dcraw applies professional white balance and color processing to produce high-quality output. The result looks excellent for sharing, printing, and web use.

What about white balance and exposure adjustments?

dcraw automatically applies the camera's recorded white balance settings. Unlike Lightroom or Capture One, you can't manually adjust exposure or color temperature before conversion. If you need creative control over RAW processing, use dedicated RAW software first.

Can I batch convert multiple ARW files?

The web interface handles one file at a time. For batch processing, use the authenticated API (/v1/convert) which supports programmatic access for automated workflows.

Is the conversion secure?

Your ARW file is uploaded via encrypted TLS, processed on our servers using dcraw, and automatically deleted immediately after conversion. We never store, view, or analyze your photos.

What's the maximum file size?

The web converter accepts files up to 25MB (free tier; 500MB on Pro), which covers most ARW files. High-resolution cameras may produce larger RAW files — the authenticated API supports up to 500MB.

Is TIFF the best format for archiving ARW photos?

TIFF preserves maximum quality with uncompressed data, making it excellent for archival. However, the original ARW file actually contains more data (12-14 bit RAW). For true archival, keep the RAW file. Use TIFF when you need a universal archival format that any software can open.

Can I use the TIFF for professional printing?

Yes. TIFF is the standard format for professional print workflows. The output includes full color data at the sensor's native resolution, suitable for large format prints and commercial printing.

Why is the TIFF file so large?

TIFF stores uncompressed pixel data. A 24-megapixel ARW file produces roughly a 70MB TIFF (24M pixels × 3 bytes/pixel). This is the tradeoff for guaranteed archival quality with zero compression artifacts.
