Welkom bij de stroopwafel GIF hotline!
Deze functionaliteit is momenteel helaas offline voor onderhoud. Gelukkig is vergelijkbare functionaliteit ook elders beschikbaar:
Op <https://gifrun.com/> kunt u bijvoorbeeld via een web-interface gifjes maken van youtube-filmpjes. Geavanceerde gebruikers kunnen u ook <https://youtube-dl.org/> proberen, waarna u gifjes kan genereren via bijvoorbeeld <https://ezgif.com/>.

Namens de directie van Stroopwafel B.V. onze excuses voor dit ongemak.""")
