How to Use Compress DOCX

Compressing Word Documents

Word files get huge when they have lots of images or have been edited by multiple people. This compresses them down - sometimes by 75% - while keeping everything readable. Good for email attachments that won't send because they're too big, or for saving space in cloud storage. Compresses images, removes unused formatting styles, strips edit history, all that stuff.

Everything processes in your browser. File stays on your computer.

Upload

  • Click upload or drag your .docx or .doc file in.
  • Handles files up to 200MB.
  • Shows filename and original size.

Pick Compression Level

  • Three options:
  • Maximum: Smallest file (60-75% reduction). Images get compressed hard (70% quality), 96 DPI, converted to WebP. Use this for email attachments.
  • Balanced: Middle ground (40-60% reduction). 85% image quality, 150 DPI, WebP conversion. Good for most situations.
  • Quality: Light compression (20-35% reduction). 95% quality, 300 DPI, keeps original formats. For professional docs or stuff you're printing.
  • Each shows what it does so you know what you're getting.

Advanced Options

  • Click advanced if you want more control:
  • Image quality slider: 50% (tiny) to 100% (highest quality).
  • DPI slider: 72 (screen only) to 300 (print quality).
  • WebP conversion: Newer format that compresses better than JPEG.
  • Remove unused styles: Dumps formatting definitions nobody's using.
  • Remove duplicates: If the same image appears multiple times, only keeps one copy.
  • Optimize XML: Compresses the file structure itself.
  • Remove history: Strips tracked changes and edit history.
  • Strip metadata: Removes author info, dates, etc.
  • Optimize fonts: Only embeds characters actually used.

Start Compressing

  • Hit compress.
  • Progress bar shows it working through stages - analyzing, compressing images, cleaning up content, optimizing structure.
  • Usually takes seconds. Big files with tons of images take longer.

Results

  • After it's done:
  • Original size vs compressed size.
  • How much you saved.
  • Percentage reduction.
  • Chart showing where the space came from - images, styles, XML, fonts, metadata.
  • Stats on how many images got processed, styles removed, etc.

Download

  • Click download.
  • Saves with "_COMPRESSED" in filename.
  • Opens normally in Word, Google Docs, whatever.
  • Content and formatting look the same. Just smaller file.

What Gets Compressed:

  • Images: Main source of savings usually. Quality stays decent even with compression.
  • Styles: Removes formatting definitions nobody's using.
  • Duplicates: If the same image is in there 5 times, only keeps one.
  • Structure: Compresses the XML that makes up the .docx file.
  • Fonts: Only embeds characters you actually use instead of entire fonts.
  • Metadata: Author info, dates, edit history.

When to Use Each Level:

  • Maximum: Email attachments with size limits.
  • Balanced: Most everyday sharing and uploading.
  • Quality: Professional docs you're printing or presenting.

Other Stuff:

  • Quality stays good: Even at max compression, text is perfect and images look fine.
  • Works everywhere: Opens in Word, Google Docs, LibreOffice, whatever.
  • In-browser: File never uploads to a server. Stays on your computer.
  • Can hit 75% reduction: Really bloated files compress a ton.

Upload, pick compression level, download. Good for email attachments that are too big, saving cloud storage space, or just shrinking files that have gotten huge over time.
