FAQ
PDF Compress questions.
Does the PDF compressor upload my file?
No. The compressor reads the PDF in your browser and creates a local download.
Why did my PDF not get much smaller?
Some PDFs are already optimized. For stronger reduction on scans or image-heavy PDFs, choose the image-based compression type.
