How It Works
Step 1: Allocate room for dense pages
A six-page agreement has 600 KB / 6 pages = 100 KB per page before PDF overhead. Distinguish plain clauses from scanned signature pages: tiny annotations and stamps may need more detail than a mostly empty page.
Step 2: Use 600 KB as a ceiling
Run compression from the original PDF. The engine searches JPEG quality at successive page resolutions; it does not preserve text objects while selectively shrinking photos. A digital agreement may lose search, and a scanned signature can soften.
Step 3: Check the evidence that matters
Inspect handwritten initials, footnotes and exhibit labels in the download. If Best Effort Result is still over 600,000 bytes, use 800 KB only if accepted. If 600 KB is mandatory, extract the requested agreement or exhibits rather than discarding required evidence.
Why Use This Tool
- 600 KB is 100 KB more than 500 KB: a 20% increase that can matter for a short, dense packet.
- A decimal byte check distinguishes a valid output from an attractive rounded size label.
- You can keep an already-compliant original without forcing a JPEG rebuild.
- The returned candidate is reviewable even when the target is missed, with the failure clearly labelled.
Common Use Cases
For example, prepare a short agreement with a signature sheet, a compact evidence extract or a statement with dense footnotes when the recipient specifies 600 KB. Quality review should focus on initials, punctuation and small exhibit references. Photos of signed pages with shadows are a harder input than a clean scan. Keep the source for searching, printing and any later review of the full record.

Frequently asked questions
Does 600 KB give six pages enough space?
600 KB / 6 pages = 100 KB per page before overhead. That is a planning average, not a six-page guarantee. Plain text clauses, noisy signature scans and photo exhibits spend the image budget differently, so review every required page.
What changes when I move from 500 KB to 600 KB?
The ceiling rises by 100 KB, or 20%. This can allow a less aggressive result, but quality is still source-dependent. The compressor tests image quality and page resolution; it does not guarantee that an extra 100 KB preserves a particular stamp or signature.
Will a 600 KB agreement still support text search?
Do not assume so. When compression is needed, pages are rendered as JPEG images inside a new PDF. Digital text can lose search and selection, while scanned fine print and photo detail can soften. Keep the original and inspect initials and footnotes in the export.
What should I do with a 600 KB Best Effort Result?
Read the exact bytes: an over-limit result has not met 600,000 bytes, even though it is available to review. The engine can retain the original if candidates would be larger. Try 800 KB if permitted; otherwise extract only the required sections or use a cleaner scan.
