In der heutigen CAD- und Ingenieurswelt ist die präzise Handhabung von Bilddaten entscheidend. Oftmals stehen Unternehmen vor der Herausforderung, moderne, weboptimierte Formate wie WEBP in ältere, aber in spezifischen Arbeitsabläufen noch fest verankerte Standards wie SUN (Sun Raster) zu überführen. Dies kann aus Kompatibilitätsgründen mit spezialisierter Software, Archivierungsnotwendigkeiten oder der Integration in bestehende, teils jahrzehntealte Systeme resultieren. Unser Konverter wurde entwickelt, um diesen Übergang nahtlos und verlustfrei zu gestalten. Wir verstehen die Notwendigkeit von Datenintegrität und Effizienz, besonders wenn es um technische Dokumentationen oder bildgestützte Analyseprozesse geht. Verlassen Sie sich auf eine Lösung, die nicht nur technisch einwandfrei funktioniert, sondern auch den hohen Anforderungen an Datenschutz und Verlässlichkeit gerecht wird, die in DACH-Unternehmen Standard sind.

In einigen deutschen Ingenieurbüros und Forschungseinrichtungen wird das SUN-Format aufgrund seiner Einfachheit und frühen Verbreitung auf UNIX-Workstations weiterhin für bestimmte Legacy-Anwendungen genutzt, insbesondere bei der Darstellung von Rastergrafiken in älteren Simulationsprogrammen.
About WEBP to SUN Conversion
WEBP (introduced 2010) and SUN are both image formats, but they differ in important ways. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. SUN is a widely used file format.
When you convert WEBP to SUN, the goal is to convert between formats quickly. Converting WEBP to SUN maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your WEBP file is decoded and re-encoded as SUN. The conversion involves 4 steps: (1) your webp file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in sun format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you need a SUN file. For the opposite direction, CocoConvert also supports SUN to WEBP conversion.
How to Convert WEBP to SUN
- 1
Upload .webp file
Select your WEBP file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .sun
Set SUN as the output format. The converter uses optimal settings based on the WEBP→SUN conversion profile.
- 3
Convert
The server-side engine decodes your WEBP file and re-encodes it as SUN. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .sun file. Multiple output files can be downloaded together.

Frequently Asked Questions
What is the difference between WEBP and SUN?
WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. SUN is a widely used file format.
Does WEBP to SUN conversion affect quality?
Converting WEBP to SUN maintains high quality with CocoConvert's optimised encoder settings.
Which format has better compression, WEBP or SUN?
WEBP uses both compression. SUN is widely supported. The better choice depends on whether you prioritize file size or quality.
How long does WEBP to SUN conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is WEBP or SUN better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
