It depends on content. Image-heavy PDFs (presentations, scanned documents) typically shrink 60–80%. Text-only PDFs (CVs, reports) compress 20–40% since they're already small. Run a second pass to compress further.
No. Text remains perfectly sharp (it's vector data). Images are re-encoded at high quality — the difference is imperceptible to the human eye at normal viewing sizes.
Yes. Download the compressed file and upload it again. Each pass removes additional redundancy. After 2–3 passes you typically reach the minimum achievable size.
Comparable quality at zero cost. Adobe Acrobat Pro costs $30/month for the same compression result. PDFTash uses Ghostscript — the same engine that powers many professional compression tools.
