Frequently asked questions

How much will my file be reduced?

Results vary by PDF type. Image-heavy PDFs typically see 30–70% reduction. Text-only PDFs may see 10–30% savings.

Will compression affect text readability?

No — text and vector content are lossless. Images may be slightly recompressed but at a quality level that remains visually clean.

What if my PDF is already optimized?

The tool will still return a valid PDF. If no further compression is possible, the output size will be close to the original.
