Common mistakes to avoid
- Optimiser sans sauvegarder l'original : impossible de revenir en arrière.
- Compresser les images au maximum : photos floues dans le document.
- Supprimer les polices intégrées : affichage cassé chez les destinataires sans la police.
Pro tips
- Compressez les images à 150 DPI pour le web, 300 DPI pour l'impression.
- Supprimez les versions anciennes et données personnelles avant envoi externe.
- Un .docx optimisé pèse souvent 50 à 80 % de moins qu'à l'origine.

Optimize and Reduce the Size of Your Word Documents
Lighten your bulky DOCX files without visible loss of quality. Ideal for email, archiving, or web publication, Word optimization compresses images and internal resources while preserving the layout.
Compress Embedded Images
High-resolution images often account for 80% of a document's weight. Our tool intelligently recompresses them to drastically reduce the size of the final file.
Clean Up Unused Resources
Orphaned styles, superfluous embedded fonts, and residual metadata are removed to produce a compact, clean, and share-ready file.
Preserve Editorial Quality and Layout
Our algorithm maintains text readability, font fidelity, and table structure. Optimization remains invisible to the reader while freeing up significant storage space.
Text, Titles, and Styles Intact
The hierarchy of your titles, your custom styles, and pagination remain identical after optimization. No manual reprocessing is necessary.
Tables, Lists, and Links Preserved
Complex tables, bulleted lists, hyperlinks, and bookmarks are preserved identically to ensure an unchanged reading experience.
Use Cases: Emailing, Archiving, and Web Publishing
An optimized Word document easily passes Gmail and Outlook attachment limits, speeds up downloads on intranets, and reduces cloud storage costs for teams managing thousands of documents.
Bypass Email Attachment Limits
Reduce a 30 MB report to 5 MB to meet Gmail, Outlook, or Yahoo quotas. No third-party transfer service needed.
Optimize for Web Download and SEO
A lightweight file downloads faster, improves user experience, and boosts the SEO of pages hosting downloadable documents.
