What is FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

What is WEBP2?

WebP2 is the next-generation image format from Google, building on the success of WebP with significantly improved compression efficiency. It targets 30% additional size reduction over WebP at equivalent quality.

When Should You Use FITS vs WEBP2?

FITS vs WEBP2: Key Differences

• •FITS and WEBP2 diverge on compression: lossless compression for the source, lossy compression for the target.
• •Moving from FITS (lossy) to WEBP2 (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: WEBP2 does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: Varies from 1MB to several GB for FITS vs 30-50% smaller than JPEG, 15-20% smaller than WebP for WEBP2.
• •Primary audience: FITS is built for astronomy, scientific imaging, research scenarios, while WEBP2 focuses on high-efficiency web graphics, next-gen responsive images — pick the format that matches your output requirement.

Advantages of FITS

• ✓FITS uses lossless compression tailored for Astronomy, scientific imaging, research.
• ✓FITS is supported natively on virtually every device, browser, and operating system.
• ✓FITS files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓FITS integrates seamlessly with all major creative tools and workflows.

Advantages of WEBP2

• ✓WEBP2 applies lossy compression specifically calibrated for High-efficiency web graphics, next-gen responsive images.
• ✓WEBP2 enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓WEBP2 delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find WEBP2 support built into virtually every tool that handles High-efficiency web graphics, next-gen responsive images — no plugins or converters needed.

Best Practices for FITS to WEBP2 Conversion

• →When converting FITS to WEBP2, check whether WEBP2 supports transparency — if not, your transparent areas will be filled with a solid color
• →Use WEBP2 for maximum quality archival and FITS for lossless workflows
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting FITS to WEBP2 Conversion

• !Converting FITS to WEBP2 gives blurry output → increase the quality setting before conversion
• !Colors look different in WEBP2 than FITS → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → WEBP2 uses different compression, file size differences of 2-5x are normal
• !Transparent areas in FITS turned white in WEBP2 → WEBP2 may not support transparency
