How it works
- Select a PDF.
- Choose light, balanced or strong compression.
- Compare original size, final size and percentage saved.
- Download the result when a real improvement is achieved.
Practical example
An 18 MB scanned PDF may shrink substantially at the balanced level, while an optimized text PDF may not shrink at all.
Formula and explanation
Cifrivo renders each page and embeds it again as a compressed image.
This works well for scans, but flattens the document and may remove selectable text.
