How It Works
Step 1: Estimate a larger bundle
A fifty-page bundle divides 10,000 KB / 50 pages = 200 KB per page before PDF overhead. Use this to assess the pressure on annotated scans and image pages, not as a guarantee that fifty pages will fit.
Step 2: Compress within browser memory
Select the original and target 10,000,000 bytes. The reduction path renders pages as JPEGs and can lower resolution. Text may lose selection, scans may lose fine annotations and photo pages can show artifacts. A larger output budget does not eliminate browser memory limits.
Step 3: Inspect the detail-bearing pages
Review handwritten notes, legend keys and small captions in the download. Best Effort Result over 10 MB means the cap was missed. Use 25 MB only if allowed; otherwise extract required sections or split the bundle when the recipient accepts separate files.
Why Use This Tool
- Keeps the ceiling explicit for a substantial bundle rather than promising a page count.
- Uses a decimal byte proof so a binary file-size display cannot hide a 10,000,000-byte miss.
- A compliant original is returned without an unnecessary image rebuild.
Common Use Cases
Prepare a reference bundle, a document review packet or a set of annotated scans for a field specifying 10 MB. Compare the page with the smallest handwriting, not just the first page. For image-heavy evidence, retain the originals and consider an accepted 25 MB ceiling if detail is lost.

Frequently asked questions
Can fifty annotated pages fit inside 10 MB?
10,000 KB / 50 pages = 200 KB per page before PDF overhead. It is a budget example, not a tested capacity. Sparse digital pages, dense annotations and full-page photos can produce very different results.
Does a 10 MB target avoid quality loss?
No size target guarantees that. Reduction rebuilds pages as JPEG images, potentially losing text selection and search, softening scanned notes and reducing photo detail. Inspect the output and retain the original. Files already within 10,000,000 bytes are returned without compression.
Why can a large PDF fail even with a 10 MB budget?
Output size and working memory are different constraints. Page rendering can exceed browser resources or fail. ExactPDF shows a recovery error for processing failures; if an over-budget candidate is returned, it is labelled Best Effort Result with the actual byte count.
What is the next target after 10 MB?
The next larger dedicated ladder page is 25 MB; choose it only if the destination accepts that size. The neighbouring stricter option is 5 MB. For a fixed 10 MB limit, extract required sections or split into separate files only when permitted.
