Features

Slides matched by content, not position

If someone inserted a slide near the start, the slides after it are still recognised as the same slides. You see one added slide, not twenty changed ones.

Before and after, side by side

Each difference comes with a picture of the old and the new slide, with the changed areas outlined.

Exact text changes

For every changed slide you get the old wording and the new wording, plus text that was added or removed, including tables.

Pictures, notes and look

Replaced pictures and edited speaker notes are listed. A slide with the same words but a different position, size, colour or font is reported as a change in look.

Moved and removed slides

A slide that reappears elsewhere in the deck is reported as moved, with its old and new number. Slides that are gone are listed as removed.

A report you can send

The full report is a PDF with a summary page and one page per difference, ready to forward to whoever needs to approve the changes.

When a colleague or client sends back version 7 of a deck, finding what they changed means flipping between two windows slide by slide. Upload the old file and the new file here and you get the answer in seconds: which slides changed, which were added, removed or moved, the exact wording that changed, and a before-and-after picture of each one. The first differences are shown in full for free.

Frequently Asked Questions

Does PowerPoint have a compare feature?

The desktop app has Review > Compare, which merges two files and asks you to accept or reject each change one at a time. This tool gives you the whole list at once, with before-and-after pictures, in the browser, and nothing in either file is modified.

What kinds of changes does it find?

Changed, added and removed text (including tables), replaced or added pictures, edited speaker notes, slides that were added, removed or moved, and slides whose look changed while the words stayed the same.

Are my files changed?

No. Both files are only read. The result is a separate report.

What is free and what is paid?

The counts, the status of every slide and the first three differences in full detail are free. The full report with every difference uses credits or a plan.

How big can the files be?

Up to 60 MB and 120 slides each. Pictures of the slides are made for the first 80 slides; beyond that the comparison is by text, pictures and notes.

Can it compare a PDF with a PowerPoint?

Not yet. Both files need to be .pptx. If one is a PDF, convert it to PowerPoint first, though a converted file will show many layout differences.
