Why do websites reject my PDF?
Most portals that accept documents limit the size of each file. When your PDF is over the limit the upload fails, often with no explanation. Scanned pages and phone photos are the usual cause, since every page becomes a large image.
How the compression works
We first try lossless optimisation. If that's enough, text stays selectable. If not, pages are re-rendered as optimised images and quality is tuned automatically until the file fits the size you picked.
FAQ
Why pick an exact size?
Many portals reject files above a limit. Here you choose the limit and the PDF comes out under it.
Will text stay selectable?
If lossless optimisation is enough, yes. When stronger reduction is needed, pages become optimised images, which works great for scans but text is no longer selectable.
Is it really free?
Yes. No daily limits and no sign-up.
