Page Balance Check - Free Online Browser Tool

Report ink coverage and image load page by page, so you know which pages will print heavy.

Print cost is driven by how much of the sheet is covered, and one page of solid artwork can cost more than the rest of the document combined. This measures coverage per page so you know where the pressure is before it reaches the printer.

How to Use the Page Balance Check Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the document

    Every page is rendered and measured, so allow time on a long document.

  2. Set the threshold

    Twenty percent is a sensible default for flagging the pages worth revisiting.

  3. Optionally include page sizes

    Helpful when handing the report to someone who needs the full specification.

  4. Download the report

    Each page gets an ink percentage, a colour percentage and a verbal label.

Frequently Asked Questions

What counts as heavy?

Around 30% coverage upward, where the ink cost climbs sharply. The report labels each page so you can see which ones those are without doing the arithmetic.

What does the colour percentage mean?

The share of pixels where the colour channels differ noticeably, which distinguishes genuinely colour content from grey text. Anti-aliased edges are excluded so grey type is not miscounted as colour.

Will it reduce the file size?

No. This is a report, not a conversion. Use it to decide which pages to simplify, then act on those pages separately.

Does it account for images versus text?

No, it measures coverage, which is what drives cost. A page of dense text and a page of a photograph can score similarly and cost very differently once they are printed.

Why does it flag blank pages?

Because a blank page is still a sheet, and in a batch run a document with a dozen blanks is paying for them. The report makes the count visible.
