Technical Specifications & Limits

  • Maximum file size: Up to 50 MB.
  • JPEG transparency: JPEG does not support alpha channels; transparent regions are filled with your chosen background color (default white).
  • Animated GIFs: Transcoding exports the primary first frame as a high-fidelity static image.

Troubleshooting Common Issues

⚠Converting PNG to JPEG turned transparent regions black.

JPEG cannot store transparency. Choose a background fill color (e.g. white or light gray) in the converter options to composite behind the image.

⚠WebP is not opening on an older desktop application.

WebP is a modern web standard. Convert the image to PNG or JPEG for legacy image viewers.

Frequently Asked Questions

Does this simply rename the file extension?

No! SciHive performs genuine pixel re-encoding through HTML5 canvas and blob serializers, writing the authentic binary container and MIME headers.

Which format should I choose for modern web pages?

WebP offers the best balance, delivering 25–35% smaller file sizes than JPEG while supporting full alpha transparency.

Can I convert vector SVGs to raster PNGs?

Yes, uploading an SVG will render and rasterize the vector paths into crisp PNG or JPEG images at your chosen resolution.
