How It Works
Step 1: Plan around the complete report
A thirty-page report divides 3,000 KB / 30 pages = 100 KB per page before PDF overhead. Count diagrams, scanned appendices and photo pages separately from plain text when judging whether that average is realistic.
Step 2: Compress toward 3,000,000 bytes
Run the target from the original file. ExactPDF rebuilds over-budget pages as JPEG images and tests quality at successive resolutions. Digital text can lose search; scanned tables may blur, and photo evidence may lose texture or fine features.
Step 3: Review the appendix as carefully as the cover
Check small table headings, drawing callouts and the least legible scanned page. Best Effort Result over 3 MB has not met the cap. If accepted, 5 MB adds 2,000 KB of space. If the limit is fixed, split sections only when the recipient allows multiple files.
Why Use This Tool
- Keeps the decision tied to a 3 MB receiving ceiling rather than a generic percentage reduction.
- Thirty text pages and thirty camera scans can require very different compromises.
- A result includes exact bytes so an over-limit packet cannot masquerade as a valid submission.
- The original remains the best starting point for retries at 2 MB or 5 MB; repeated JPEG rebuilding cannot recover lost detail.
Common Use Cases
For example, prepare a compact technical report, a proposal with an appendix or a set of scanned supporting records for a destination that explicitly allows 3 MB. Thin drawing lines and small numerical labels need a closer check than a large heading. This target is a delivery budget, not a preservation format for detailed originals. A shorter extract may be more useful than reducing the entire report until its appendix becomes unreadable.

Frequently asked questions
Is 3 MB enough for a thirty-page report?
3,000 KB / 30 pages = 100 KB per page before the PDF structure uses any bytes. That example is a planning constraint, not a claim about how many pages will fit. Text-only material, scanned appendices and photo pages have different detail requirements.
What should I inspect in a 3 MB technical PDF?
Look at drawing callouts, thin lines, table headings and scanned footnotes in the download. The reduction path rebuilds whole pages as JPEG images; digital text can lose selection and scans or photos can lose fine detail. Keep the original for printing and searching.
Why can an already-compact report miss 3 MB?
Rasterizing lean digital pages may not save space. If no under-budget candidate is found, ExactPDF shows Best Effort Result with actual bytes and keeps the original when image candidates would be larger. That is a target miss, not a certified readable minimum.
Should I retry at 2 MB or 5 MB?
Use 5 MB if permitted when 3 MB is unreachable or damages required detail; it adds 2,000 KB to the whole-file budget. Use 2 MB only for a stricter receiving limit. For a fixed 3 MB cap, extract or split sections only as the submission instructions allow.
