Frequently Asked Questions

How much smaller will my PDF actually get?▼
Depèn del contingut. Els PDF pesats en imatges (escaneigs, informes fotogràfics) poden reduir-se fins a un 80%, mentre que els documents només de text solen veure una reducció més modesta del 10 al 30%, ja que hi ha menys per optimitzar.
El meu PDF es veurà borrós després de comprimir-lo?▼
Only if you choose "Extreme," which trades some image sharpness for the smallest possible file. "Recommended" is built to keep text crisp and images clear while still cutting the file down significantly.
Is there a file size limit for compression?▼
Compression runs on your own device, so the practical ceiling is your available RAM rather than a fixed cap — most laptops and phones handle files up to 100MB comfortably.
What's the difference between the compression levels?▼
"Less" applies lossless, structure-only compression with no visible quality change. "Recommended" balances size and quality for everyday sharing. "Extreme" prioritizes the smallest file, which can slightly soften high-resolution images.
Puc comprimir un PDF que ja s'hagi comprimit una vegada?▼
Sí, tot i que els guanys seran menors la segona vegada: un cop les imatges i els fluxos ja estiguin optimitzats, simplement queden menys dades redundants per eliminar.
