Tips
- The tool compares text only, so it skips layout and images.
- Use paragraph mode for long blocks of text; line mode for structured lists.
- If a PDF is image-only, extract with “PDF to Text” first or OCR elsewhere.
How to use Compare PDFs (Text) effectively
Use this browser-only PDF workflow with one clear output goal: choose the file, confirm the relevant pages or format settings, and export a test result before sharing.
How it works
The page reads the selected PDF in your browser and prepares a new output file from the settings you choose. Keep the source file unchanged, review the preview or downloaded sample, and repeat with adjusted settings only when the output does not match the intended use.
When to use
Use this tool for quick PDF cleanup, conversion, annotation, or extraction tasks when you want a local workflow without uploading the document to a server.
Common mistakes to avoid
- Exporting a large document before testing one small sample.
- Assuming all PDF viewers handle fonts, images, and page boxes in exactly the same way.
- Overwriting the original file before checking the downloaded result.
- Using browser output for regulated documents without your normal document review step.

FAQ
What should I check before exporting a PDF?
Load the PDF, confirm the page range or output format, then export a small sample if the file is large. This keeps browser-only processing predictable.
Why might another PDF tool produce a different file?
PDF tools can choose different image settings, font handling, compression levels, or page box rules. Compare a preview page before using the output in a workflow.
Can I rely on the exported PDF?
Use the preview and a quick download check before sharing. Browser processing is useful for everyday edits, but sensitive or regulated documents should be reviewed in your normal document workflow.
Can I reproduce the same export later?
Yes if you keep the same source file and settings. Save the output with a clear filename so the page order, format, or compression choice is easy to verify.
Are my PDF files uploaded?
PDF processing runs in your browser. Files are not uploaded automatically; only use share or external storage when you choose to.
