Download Caesium gratis herunder

Caesium, som du kan downloade gratis til Windows og Mac, kan bruges til hurtigt og enkelt at komprimere alle dine billeder!

Hvis du tager mange billeder med din mobiltelefon eller et spejlreflekskamera, så ved du også, at billederne hurtigt kan komme til at fylde rigtig meget. Hvis du har en stor harddisk, så er dette ikke et problem, men hvis du nu ønsker at dele dem med vennerne på din blog eller en online fildelingstjeneste, så kan det godt være, at du løber ind i pladsproblemer. Dette problem kan du løse med billedkomprimeringsværktøjet Caesium!



Caesium er open source og derfor helt gratis! Vi har lavet en lille test af Windows-udgaven af programmet, og her på siden har vi skrevet lidt om, hvordan programmet fungerer. Caesium er også tilængelig til Mac, og vi gætter på, at programmet fungerer cirka ens på begge operativsystemer.


Desuden vil vi lige nævne, at det er meget vigtigt at huske på, at når man komprimerer og formindsker sine billeder, så mister de også billedkvalitet. Derfor anbefaler vi, at man aldrig sletter de originale billedfiler, medmindre man er helt sikker på, at man ikke får brug for filerne igen på et senere tidspunkt.


Sådan downloades Caesium


Det allerførste skridt er selvfølgelig at hente og installere Caesium på computeren. Det er ikke vigtigt, om du bruger Windows eller Mac, for når du trykker på download-knappen her på siden, så bliver du ført videre til programmets officielle hjemmeside, hvor alle installationsfilerne er tilgængelige.


Da vi selv testede Caesium, gjorde vi det på en PC med Windows 11. Installationsprocessen kan ses på GIF-billedet nedenfor.



Da vi installerede programmet, der blev vi bedt om at vælge, hvor vi ønskede at installere det på computeren, samt om vi ønskede en skrivebordsgenvej. Herefter var Caesium installeret efter et kort øjeblik.


Desuden er det værd at nævne, at Caesium også kan downloades som en transportabel applikation til Windows. Vælger man denne udgave, så kan man overføre programmet til en ekstern harddisk, et USB-stik eller lignende, som man kan køre programmet fra på andre computere. Hvis du synes, at transportable applikationer lyder spændende, så kan vi anbefale dig at læse vores anmeldelse af værktøjet PortableApps.com på dette link.


Start med at importere billeder


Efter installationen af Caesium, så skal du selvfølgelig starte med at tilføje de billeder til programmet, som du ønsker at komprimere. Brugerfladen i Caesium er ekstremt simpel, så dette tager ingen tid. Med knapperne i toppen af programmet kan du vælge enten at importere enkelte billedfiler eller en hel mappe.


Hvis du fx har billederne liggende på skrivebordet, så kan du også bare gribe fat i dem med musen og trække dem direkte ind i Caesium. Nemt og super smart! Herefter skal du vælge de ønskede komprimerings- og resizing-indstillinger, som det bliver beskrevet i de følgende afsnit.


Komprimeringsindstillinger


Med Caesium kan du både komprimere dine billeder og formindske dem i bredden og højden. Ønsker du at gøre det førstnævnte, så kan du indstille, hvordan Caesium skal komprimere dine billeder ved at klikke på “Compression” ude i højre side af programmet.


På nedenstående skærmbillede kan du se de forskellige komprimeringsindstillinger.



Caesium understøtter filtyperne JPEG, PNG og WebP. Ved at trække i de forskellige sliders kan du styre komprimeringen. Jo mere du komprimerer dine billeder, jo mindre kommer de til at fylde, men til gengæld mister du også mere billedkvalitet.


Resizing-indstillinger


Det er også muligt at ændre opløsningen på dine billeder ved at foretage en resizing af dem. Dette gør du ved at klikke på knappen “Resize”.



Når et billede resizes, så formindsker du billedets antal pixels. Vælger du eksempelvis højden og bredden skal være en tredjedel mindre, så kommer billeder også til at fylde endnu mindre plads. Til gengæld bliver billedet hurtigere pixeleret, hvis du zoomer for langt ind på det.


Output-indstillinger


Når du har besluttet dig for, hvordan dine billeder skal komprimeres og resizes, så skal du klikke på knappen “Output”. Herinde kan du indstille, hvordan Caesium skal eksportere dine billeder.



Først og fremmest skal du vælge hvor på computeren, at Caesium skal eksportere billederne til. Det kan selvfølgelig være lige præcis den filplacering, som du ønsker. Derudover kan du også styre filnavnene på de nye billeder ved at skrive noget i tekstfeltet “Suffix”. Herefter trykker du på “Compress”-knappen, og så klarer Caesium resten.


Når komprimeringen er færdig, så er det muligt at se det originale billede og det komprimerede billede side om side nede i bunden af Caesium. Dette er super smart, for så kan du hurtigt få en fornemmelse for, om komprimeringen har kostet for meget på billedkvaliteten.


Når man deler sine billeder på internettet, så er det sommetider smart at indsætte et lille vandmærke på dem, så alle ved, hvor billederne kommer fra. Sådan en funktion kunne vi ikke finde i Caesium, men det er også det eneste minus ved programmet, som vi kan komme i tanke op.


Alternativ: Online Caesium-app


Her til sidst vil vi lige nævne, at Caesium faktisk også eksisterer som en slags online app på internettet, som du kan anvende direkte i din internetbrowser. Appen finder du ved at klikke dig ind på hjemmesiden caesium.app.


Online-applikationen er super simpel at anvende, men der er dog nogle væsentlige restriktioner. Eksempelvis kan du højest komprimere 5 filer ad gangen, og hver fil må højest fylde 10 MB. Desuden er der slet ikke en resizing-funktion til at formindske højden og bredden på billeder med.


Vi synes, at online-versionen af Caesium er super smart, men den kan altså kun bruges til meget simple formål. Ønsker du den fulde funktionalitet, så skal du altså hente og installere programmet.


Samlet vurdering


Som du kan læse her på siden, så synes vi, at Caesium er et smart lille værktøj!


Det eneste nævneværdige minus, som vi kan komme i tanke om, er manglen på en vandmærke-funktion, men ellers er vi ret begrejstrede for Caesium! Programmet er jo gratis og både tilgængeligt til Windows og Mac, så vi synes egentlig ikke, at man kan forlange så meget mere.


Så hvis du står og mangler et billedkomprimeringsprogram, så er Caesium et godt bud på et smart stykke software!
