300KB sits in a practical middle ground — strict enough to require actual compression for most scanned documents, but forgiving enough that the result usually looks fine. You will hit this limit on court e-filing portals, some insurance claim forms, LMS platforms like Moodle, and vendor registration systems.
Contracts, lease agreements, and legal correspondence often need to be submitted through portals that were not designed with large PDFs in mind. A scanned contract with several pages can easily be 2–5MB. Getting it down to 300KB is very doable for a 2–3 page document, though quality will be reduced on any scanned images or photos within the file.
Text-only PDFs — like a Word document exported to PDF — compress extremely well and will often come in well under 300KB with no visible changes at all. The tricky ones are scanned documents and PDFs with embedded images, charts, or photographs.
If your portal allows 500KB, use our Compress PDF to 500KB tool instead — the extra headroom means noticeably better output quality. For tighter limits, see 200KB or 50KB.
Text-heavy PDFs compress very easily and will usually hit 300KB with no quality loss. Scanned documents and image-heavy PDFs require more aggressive compression and will have some visible quality reduction.
It depends on the court system. Some accept up to 500KB or 1MB per document. Check the specific portal requirements — if 500KB is allowed, use our Compress PDF to 500KB tool for better quality output.
For standard charts with clear lines and labels, yes. Dense technical diagrams with fine print may have some degradation — always preview before sending.
