How It Works
Step 1: Compare page count with image content
An eight-page report divides 800 KB / 8 pages = 100 KB per page before PDF overhead. A report with eight text pages is a different input from eight full-page charts or camera photos. Identify the pages where colour and labels carry meaning.
Step 2: Target 800,000 bytes
Choose the source and run compression. The engine renders pages into JPEG images, adjusting quality and then resolution if needed. Text may lose selection; scanned axes, coloured legends and photographic detail may become less distinct.
Step 3: Validate charts as well as text
Open the output and compare axis labels, legends and fine table rules. Best Effort Result over the displayed limit means 800 KB was not reached. If allowed, 1 MB adds 200 KB of room. For a fixed 800 KB field, shorten the packet only within its instructions.
Why Use This Tool
- 800 KB provides 80% of the decimal 1 MB budget, a useful distinction when the upload field names the smaller ceiling.
- A chart that looks acceptable as a thumbnail can still have unreadable labels; inspect the exported pages.
- The tool returns an already-compliant original without altering it.
- An over-budget candidate is shown with actual bytes rather than presented as a completed target.
Common Use Cases
Use this ceiling for a short illustrated report, a document with a few charts or a compact supporting packet when 800 KB is explicitly requested. For example, an eight-page summary with one dense chart needs a different quality review from a photo contact sheet. Preserve the original for detail-sensitive reading. If the receiving field accepts 1 MB, compare that result before accepting blurred chart labels.

Frequently asked questions
Can eight illustrated pages fit in 800 KB?
800 KB / 8 pages = 100 KB per page before PDF overhead. This is an illustration of the constraint, not a promise. Sparse text, dense charts and full-page photographs have different detail requirements; the saved output needs a page-by-page review.
How different is 800 KB from the 1 MB target?
ExactPDF uses decimal units: 800 KB is 800,000 bytes and 1 MB is 1,000,000 bytes. Moving up adds 200 KB, a 25% increase over 800 KB. Choose the larger target only when the receiving field permits it.
What quality should I expect for charts and photographs at 800 KB?
JPEG rebuilding can soften fine chart labels and introduce artifacts around coloured lines; photographs can lose texture. Digital text can lose selection and search as well. Compare the export with the original at a readable zoom instead of relying on the final size alone.
Why did compression stop above 800,000 bytes?
The available attempts did not produce an under-budget result. ExactPDF shows Best Effort Result, the exact bytes and the over-limit warning; it keeps the original when candidates would grow it. Try an allowed 1 MB target or reduce the required packet. A processing error uses a separate recovery message.
