مقارنة PDF

قارن ملفي PDF صفحة بصفحة كصور مُعالجة وأبرز ما تغيّر باللون الأحمر — بالكامل في متصفحك.

تقارن هذه الأداة صور الصفحات المعالجة، وليس النص — استبدال خط يبدو متطابقًا سيظهر بلا تغيير، بينما إزاحة بمقدار بكسل واحد في التخطيط ستظهر كتغيير.

تتم معالجة كلا الملفين في متصفحك — لا شيء يُرفع حتى تقوم بالتنزيل.

How it helps

Renders every shared page of both PDFs and highlights differences in red.
Shows a changed-percentage stat for each page.
Catches visual changes text-diff tools miss — layout shifts, image edits, formatting.
Processed in your browser until you download.

Best practices

  • - Use this for visual/layout review — contract redlines, design proofs, invoice template changes.
  • - If the two PDFs have different page counts, only the shared pages are compared; the rest is flagged.
  • - For pure text changes (a word added/removed with no layout shift), a dedicated text-diff tool may be clearer.
  • - High scan resolution or very large pages may render slower — give it a moment.

Limitations

  • - This compares rendered pixels, not underlying text — a font substitution that looks identical won't be flagged.
  • - Pages are compared independently by index; inserted or deleted pages will shift every later page's comparison.
  • - No text-level diff (word additions/deletions) is produced — only a visual highlight.

FAQ

Does this compare text or images?

Images — each page is rendered to a raster image and compared pixel by pixel. This catches any visual change, including ones that wouldn't show up in a pure text diff, but it can't tell you which words changed.

What happens if the PDFs have different page counts?

Only the pages present in both PDFs (by index) are compared; the tool flags the page-count mismatch so you know some pages weren't checked.

Why does a small formatting tweak show a large changed percentage?

If text reflows even slightly, every pixel from that point down can shift, which shows up as 'changed' even though the content itself barely differs — this is a visual diff, not a semantic one.

Is anything uploaded?

No. Both PDFs are processed entirely in your browser; nothing is sent anywhere until you choose to download a diff image.
