About Office Compression
DOCX, XLSX, and PPTX files are ZIP containers with images embedded inside. Our compressor recompresses every embedded image at ~70% JPEG quality — the text, styles, and layout stay exactly the same.
Word Documents
Image-heavy DOCX files shrink 40–70% — perfect for email and cloud storage.
Excel Spreadsheets
XLSX files with images or charts compress significantly with zero data loss.
PowerPoint
PPTX with photos compresses dramatically — ideal for presentations shared online.
Preserves Edits
After compression, the file is still fully editable — you're not flattening anything.
Frequently Asked Questions
How much smaller can Office files get?+
Typically 40–80% for image-heavy documents. Text-only documents compress very little (already small).
Will my formatting be preserved?+
Yes. Styles, headings, tables, formulas, slide layouts — all preserved. Only embedded images are recompressed.
Can I still edit the compressed file?+
Yes. The output is a normal DOCX/XLSX/PPTX — fully editable in Word, Excel, PowerPoint, or LibreOffice.
What formats are supported?+
DOCX (Word), XLSX (Excel), and PPTX (PowerPoint). Older .doc, .xls, .ppt formats aren't supported — convert them first.
Is Office compression free?+
Yes — completely free, no signup, no watermark.
