Compress PDF to 300KB Online — Free
300KB is where banking and property paperwork lives: account opening packs, insurance policies, tenancy and sale contracts, procurement submissions. These are long documents where every page has to stay readable, not a single form you can crush.
That is why this page uses balanced compression rather than the maximum setting. A ten to twenty page contract fits under 300KB with clauses, tables and signatures all still crisp.

The file is encrypted in transit, processed, and deleted automatically afterwards. Nothing is stored and nothing is shared. Compression is also lossless for text — no wording can change.
Some portals measure the encoded upload, which is slightly larger than the file on disk. Aim for around 250KB to leave headroom — target 200KB instead if it keeps failing.
