Free Grammar Checker Online — Fix Grammar & Spelling

PDF to Word

Basic text version: this extracts the readable text from a text-based PDF and saves it as an editable Word (.doc) file you can open in Microsoft Word or Google Docs. It works on PDFs that contain real text — scanned documents and complex layouts (columns, tables, images) won’t carry over.

Merge PDF

Pick two or more PDFs and they’ll be combined into a single file, in the order you selected them. Everything happens in your browser — your files are never uploaded.

    Compress PDF

    Two ways to shrink a PDF. “Re-save” tidies the file structure without touching quality. “Strong” rebuilds every page as an image at your chosen quality — much smaller for scan-heavy PDFs, but text becomes part of the image.

    JPG to PDF

    Turn one or more images (JPG, PNG, WebP and more) into a single PDF — one image per page, sized to fit the page.

      Split PDF

      Pull pages out of a PDF: either download every page as its own one-page PDF, or extract just the page range you need into a single new file.

      PDF to JPG

      Renders every page of your PDF as a JPG image and downloads them one by one (page-1.jpg, page-2.jpg…). Best for documents up to about 50 pages.

      Word to PDF

      Runs on a connected serviceConverting a Word document to PDF with its layout, fonts and tables perfectly intact needs a document-conversion service. This tool activates on the live SavyTools website — it isn’t connected yet, and no file you choose here is uploaded or converted.

      2. Run the check and review each suggested correction.
      3. Accept the corrections you agree with and ignore any that change your meaning.
      4. Read the final text once through before you send or submit it.

      Frequently Asked Questions

      Which errors does it catch?

      It catches spelling mistakes, grammar errors, missing or misplaced punctuation, and common style slips, as provided by the connected grammar service. It cannot judge whether your argument or facts are correct.

      Is my text private?

      Your text is sent to the connected grammar service for the check itself. It is not published anywhere, and you should not paste confidential or sensitive material into any online checker.

      Does it work in languages other than English?

      English is the primary language. The live tool will list any other supported languages once it is connected, so check there before pasting text in another language.

      Tips

      Ignore any suggestion that would change what you meant to say; grammar tools sometimes misread context. After accepting corrections, read the whole text once through, since a corrected sentence can still sound awkward. Use the checker as a second pair of eyes, not as a replacement for proofreading. This tool runs through a connected grammar service on the live site.
