About XLSX Compression
XLSX workbooks are packaged archives that grow large mainly from embedded images, charts and stock media. This browser-based compressor reprocesses those heavy assets and repacks the archive at higher efficiency, producing smaller Excel files for email, upload limits and storage savings — while your workbook stays on your own device the whole time.

Vanlige spørsmål
How does XLSX compression work?
XLSX files are ZIP archives containing images, charts and XML. Our tool extracts the archive, re-encodes embedded images at optimized quality levels, and repackages the workbook with efficient compression.
Will my formulas and data change?
Celledata, formler, formatering og pivottabeller forblir intakte. Bare innebygde bilder blir omkodet. Arbeidsboken vil beregne og se lik ut når den åpnes i Excel.
Hvor mye kan jeg redusere XLSX-filstørrelsen?
Arbeidsbøker med mange innebygde bilder kan krympe med 50–80 %. Arbeidsbøker som kun inneholder data ser mindre reduksjoner, hovedsakelig fra mer effektiv arkivompakking.
Er denne XLSX-kompressoren gratis?
Ja, helt gratis uten begrensninger. Behandle så mange Excel-filer du trenger, ingen registrering nødvendig.
