| Analytics | The privacy policy says DrawDiff uses Google Analytics 4 for anonymous usage data, including visited pages, general region, device category, and feature events; it says this data excludes PDF content and filenames. | Google Analytics is used for page-view and browser metrics but the site says it does not receive file contents or comparison results. |
| Intended users | The site names engineering drawing reviewers, architecture and construction teams, legal and contract reviewers, and defense and government users. | The About page identifies legal professionals, financial analysts and auditors, journalists and fact-checkers, and software developers as users. |
| Local processing | PDF data is read through the browser File API and processed in browser memory without document uploads. | Comparisons run in the browser; the site says file data is not sent to its servers or external services. |
| Offline use | The security page says the app can work offline after it has loaded and that the single-file app can be hosted on an internal web server for air-gapped environments. | After the first page load, cached libraries allow comparisons while disconnected from the internet. |
| Purpose | DrawDiff compares engineering drawings, technical documents, and contracts using pixel-accurate PDF overlays. | SmarterDiff compares text, Word documents, PDFs, spreadsheets, folders, and images in a browser without uploading files. |
| Support | The privacy policy directs questions to [email protected]. | Bug reports and feature requests are handled through a contact form requesting browser, format and problem details. |
| Text comparison | A selected PDF region can be extracted and compared at word level, with added and removed words color-coded. | Text can be compared by line, word or character, with ignore-case and ignore-whitespace options. |
| What it does | DrawDiff compares engineering drawings, technical documents, contracts and other PDF revisions with pixel-level, color-coded overlays. | SmarterDiff compares text, Word documents, PDFs, spreadsheets, folders and images inside a browser. |

In their own words
SmarterDiff
SmarterDiff is a free browser-based tool for comparing text, Word documents, PDFs, spreadsheets, folders, and images. Text comparisons can show line, word, or character differences, with options to ignore case and whitespace. Excel and CSV comparisons check cell values and formulas, while image comparisons use pixel differences with overlay, side-by-side, and slider views. It can compare finalized.docx text, but not Word tracked-change markup; scanned PDFs without embedded text cannot be compared as text. SmarterDiff says comparisons run in the browser and files or results are not sent to its servers or external services. Comparisons can work offline after the first page load while browser libraries remain cached. File size depends on available computer memory and browser limits. It is a manual, one-off tool without workflow automation or integrations. The Free plan costs nothing, is ad-supported, requires no account, and has no artificial limits.
