Frequently Asked Questions

Hoeveel kleiner wordt mijn PDF eigenlijk?▼
It depends on the content. Image-heavy PDFs (scans, photo reports) can shrink by up to 80%, while text-only documents usually see a more modest 10–30% reduction since there's less to optimize.
Zal mijn PDF er wazig uitzien na het comprimeren?▼
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.
Wat is het verschil tussen de compressieniveaus?▼
"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.
Can I compress a PDF that's already been compressed once?▼
Yes, though gains will be smaller the second time around — once images and streams are already optimized, there's simply less redundant data left to strip out.
