Frequently asked questions
- Is 500 KB a good balance?
- Often yes — 500 KB is roomy enough to keep images looking good while staying small enough for most email and upload limits.
- What kinds of PDFs shrink the most?
- Scanned documents and image-heavy PDFs shrink the most. Text-only PDFs are already small, so there's little to remove.
- Do my files get uploaded?
- No — everything runs in your browser. Your PDF never leaves your device.
500 KB: small enough to send, big enough to look good
500 KB is the comfortable middle ground. It clears most email attachment checks and upload forms while leaving enough headroom that photos, diagrams, and multi-page scans still look crisp. If 100 KB or 200 KB forced too much quality loss on your document, 500 KB is usually where images stop looking soft.
Best for image-rich and multi-page documents
This target shines on a portfolio with photographs, a report with charts and screenshots, or a scanned booklet of several pages. Because HivePDF re-encodes images per page and keeps real text selectable, you get a noticeably smaller file that still reads and prints well. If your document slips under 500 KB easily, you'll simply get a higher-quality result.
