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
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.
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.
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.
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.
The web converter accepts files up to 25MB (free tier; 100MB with eligible paid browser access), which covers most ARW files. High-resolution cameras may produce larger RAW files — the authenticated API supports up to 500MB.
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.
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.
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.
