What is BPG?

Better Portable Graphics (BPG) is a modern image format based on HEVC video compression, offering excellent compression efficiency.

What is FITS?

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

When Should You Use BPG vs FITS?

Use BPG When...

Reach for BPG when your priority is web images with superior compression — its efficient compression makes sharing fast and storage minimal.

Use FITS When...

Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.

BPG vs FITS: Key Differences

  • •BPG uses lossy compression while FITS uses lossless compression — this is the fundamental technical difference between the two formats.
  • •Moving from BPG (lossless) to FITS (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •BPG files are typically 30-50% smaller than JPEG at same quality while FITS files range Varies from 1MB to several GB
  • •Primary audience: BPG is built for web images with superior compression scenarios, while FITS focuses on astronomy, scientific imaging, research — pick the format that matches your output requirement.

Advantages of BPG

  • ✓BPG uses lossy compression tailored for Web images with superior compression.
  • ✓BPG is supported natively on virtually every device, browser, and operating system.
  • ✓BPG files are compact and quick to transfer, even over slow connections.
  • ✓BPG integrates seamlessly with all major creative tools and workflows.

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.

Best Practices for BPG to FITS Conversion

  • →When converting BPG to FITS, check whether FITS supports transparency — if not, your transparent areas will be filled with a solid color
  • →Use FITS for maximum quality archival and BPG for smaller file sizes when quality is less critical
  • →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 BPG to FITS Conversion

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

FAQs

Is converting BPG to FITS free?

Yes, GoConvertFile offers free conversion of BPG to FITS for files up to 100MB. No registration required.

How long does it take to convert BPG to FITS?

Most BPG to FITS conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is FITS best used for?

FITS is ideal for astronomy, scientific imaging, research. Flexible Image Transport System, scientific data format

Does converting BPG to FITS lose quality?

No, converting BPG to FITS does not cause additional quality loss — FITS uses lossless compression. However, any artifacts already present in the original BPG file will persist in the FITS output.

What file size should I expect after converting BPG to FITS?

FITS files are typically 2-5x larger than equivalent BPG files because FITS preserves all pixel data. This is expected and necessary for lossless quality.

Will transparency be preserved when converting BPG to FITS?

Yes, FITS supports transparency. Alpha channel information from BPG is preserved during conversion.
