Reduce PDF file size with clear before/after numbers — ideal for scans and image-heavy files.
Pages are re-rendered as optimised JPEG images at a lower resolution. That’s why it works best on scans and image-heavy PDFs — and why text in the output is no longer selectable.
PDFs that are already pure optimised text can’t be shrunk this way — we tell you instead of silently making the file bigger.
