Frequently Asked Questions

How much can the file size be reduced?
Typically 40โ€“80% depending on the content. PDFs with lots of images see the biggest reductions, while text-heavy PDFs are already fairly compact.
Will compression affect the quality?
Our smart compression uses optimized algorithms to reduce size while keeping text sharp and images clear. For most use cases, the difference is imperceptible.
Is there a file size limit?
You can compress PDFs up to 100MB. For best performance, we recommend keeping files under 50MB.
