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 WebP lets anyone view and use your photos with standard image viewers and web browsers.

Photography portfolio websites

Convert ARW photos to WebP for your portfolio site. Smaller file sizes mean faster page loads, which improves both user experience and SEO rankings.

Online gallery optimization

Photo galleries with dozens of high-resolution images benefit dramatically from WebP compression. Visitors see your photos faster, especially on mobile connections.

Blog and content marketing

Photography blogs and tutorials need high-quality images that load quickly. WebP delivers both, keeping readers engaged without bandwidth penalties.

Frequently Asked Questions

Does converting ARW to WebP 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 WebP 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.

How much smaller is WebP compared to JPG from ARW?

WebP typically produces files 25-35% smaller than JPG at equivalent visual quality. A 5MB JPG from a RAW conversion might be 3-4MB as WebP with no visible difference. This makes WebP ideal for web galleries and online portfolios.

Can I use WebP for my photography portfolio?

Yes. WebP is supported in all modern browsers and produces excellent photo quality. Many photography portfolio platforms (SmugMug, Squarespace, WordPress) accept WebP. The smaller files mean faster page loads for your visitors.

Is WebP good for social media?

Most social platforms re-encode uploaded images, so the format matters less for social media. However, WebP is useful for your own website or blog where you control the image format and want optimal loading speed.
