Show a side-by-side document comparison and easily spot changes between different file versions.
Upload two versions of a document and PDFSketch highlights added, removed, and changed text side-by-side so you can spot every difference at a glance.
Both documents are compared within a single ephemeral session — neither file is retained after your comparison results are downloaded or the session ends.
reviewing differences between two versions of a PDF This page is designed for contracts, policies, specifications, reports, approvals, and revised drafts.
Use this page when the requested PDF outcome matches the page intent and you want a focused operation without unnecessary format changes.
contracts, policies, specifications, reports, approvals, and revised drafts can use this page when the goal is a specific, repeatable document outcome rather than a general PDF edit. Start with the smallest operation that solves the problem, then use a related PDF tool only when the output requires another deliberate step.
Start with the source document and define the exact output you need. Reviewing differences between two versions of a pdf. Choose the relevant options, process the file, and inspect the result before replacing or sharing the original.
Keep a copy of the original when the operation changes pages, text, structure, permissions, or file format. Confirm the intended output format and review the source for password protection, scanned pages, unusual fonts, tables, signatures, and other elements that may affect the result.
Before you finish, review both visual and textual changes and pay special attention to dates, figures, clauses, and tables. Keep the original when the operation changes or replaces document structure, and verify the output in a normal PDF viewer when the document is important.
Assuming the tool can preserve every document feature without checking the output, especially with scans, tables, signatures, unusual fonts, or complex layouts. This is especially important when the PDF contains signatures, financial values, legal clauses, personal information, or other material that must remain accurate.
Open the output and check the pages that matter most: the first page, a representative middle page, and the final page. For conversions, also inspect tables, images, links, headings, and page breaks. For security-sensitive operations, confirm that the intended protection or removal behavior actually works before distribution.

Yes, the tool aligns matching content and clearly flags pages that were added or removed entirely.
Text content changes are the primary focus; major layout shifts are also visible in the side-by-side rendering.
Text-level diffing requires a text layer — run OCR on scanned PDFs first for accurate word-level comparison.
