Frequently asked questions
How much smaller will my PDF get?
It depends on how the file was written. PDFs from older generators or heavy editing often shrink 10β40% through structure repacking alone. Files that are already tightly packed (mostly one big scanned image) may shrink only slightly β and if no gain is possible, you get the original back unchanged.
Does compression reduce image quality or blur text?
No. This is lossless structural compression β images are not re-encoded and text is not rasterized. The document renders identically before and after.
Why is my compressed file the same size as the original?
That PDF was already optimally packed. Rather than hand you a file that grew, the tool detects this and returns your original bytes, reporting 0% savings honestly.
Is metadata removal safe?
Yes β only descriptive fields (title, author, creator software, keywords) are cleared. Nothing that affects rendering, fonts, or page content is touched.
Your files stay private
Your PDF is repacked in memory and discarded the moment the download is served. The metadata we strip is deleted, not collected β we never read or retain document contents. Account holders see only size numbers in their history.
