What counts as a difference?

Changed, inserted and removed text is flagged, along with pages whose layout has shifted. Identical pages are marked as unchanged so a long document collapses to the handful of pages worth reading.

Which document should I load first?

Load the older one first. The order decides which side is treated as the baseline, so reversing it inverts every insertion into a deletion and makes the result harder to read than it needs to be.

When is overlay mode more useful than side-by-side?

Overlay is better when you suspect content has moved rather than changed — a table nudged down a page, or a margin altered. Side-by-side is better for wording, where reading both versions matters more than seeing displacement.

About Compare Pdfs

Compare puts two revisions of the same document side by side and marks what changed between them. An overlay mode stacks the pages instead, so shifted lines and moved blocks show up as displacement rather than as two separate lists of differences.

Both documents are opened locally and compared in memory. Nothing about either revision is uploaded, logged or retained after the tab closes.

How to use Compare Pdfs

Load exactly two PDFs — the earlier revision first, the later one second.
Choose side-by-side to read both documents in parallel, or overlay to see one drawn on top of the other.
Step through the flagged pages. Differences are highlighted in place rather than listed away from their context.
Export the annotated comparison if you need to circulate the result rather than just read it.

On a production

Script revisions arrive as coloured pages, but the colour tells you only that a page changed, not what changed on it. Holding the blue draft against the pink one and seeing the altered lines highlighted turns a page-by-page read into a thirty-second check before the day's sides go out.
