Web contact forms, CMS uploads and many client portals cap attachments at 1 MB. Targeting 800 KB with EasyPDF leaves a safety margin while keeping images at a clean 150 dpi.

A 6-8 MB report reaches 800 KB with about 88% reduction while images keep 150 dpi, the resolution where charts and screenshots remain sharp on screen. The 200 KB margin under a 1 MB cap absorbs metadata added by portals at upload time.

For 1 MB form limits with margin, e-invoices, newsletters and reports that must stay light but presentable.

Frequently Asked Questions

How do I compress a PDF to 800 KB?

Upload it to EasyPDF and choose balanced compression. A 6-8 MB report typically lands near 800 KB with images kept at 150 dpi.

Why target 800 KB instead of exactly 1 MB?

Upload fields often add metadata or reject files at the boundary. An 800 KB file keeps a 20% margin so the upload never bounces at 1.01 MB.

Will charts and screenshots survive at 800 KB?

Yes. At 150 dpi, charts, tables and interface screenshots stay sharp on screen. Only fine print inside dense images may need zooming.

Can I compress a 800 kb PDF without converting it?

Yes, EasyPDF lets you compress your 800 kb PDF directly without converting it to another format. The original PDF structure and formatting are preserved.

Is it safe to compress 800 kb PDFs online?

Absolutely. EasyPDF processes all files client-side in your browser. Your 800 kb PDFs are never uploaded to any server, ensuring complete privacy and security.
