Honest PDF compression with measured output
Recommended compression safely rebuilds the PDF structure and removes avoidable metadata. Maximum compression rasterizes pages, which can reduce image-heavy files more substantially but removes selectable text. Vinverse reports the real generated size and never invents savings.
Two approaches
Choose structure-safe optimization or stronger rasterized output.
Honest outcome
Already optimized files are reported clearly instead of showing fake reductions.
Questions
Frequently asked questions
Why did my PDF barely shrink?
Some PDFs are already optimized or mostly contain compact text and vector data. In that case there may be little safe data to remove.
What does Maximum Compression change?
It rebuilds pages as compressed images. This is effective for scans, but selectable text and links are not retained.
Is the PDF uploaded?
No. Both compression modes run locally in your browser.
