PackFit — Shrink Office & ZIP Files 作者： Mrrage

Get a Word, Excel or PowerPoint file under an email size limit — without uploading it.

• Shrinks .docx, .xlsx, .pptx and .zip by recompressing the images inside
• Your file stays valid — Office reopens the shrunk copy normally
• Your original is left untouched; the smaller copy downloads separately
• See exactly which images were recompressed and by how much
• 100% on-device: no upload, no server, nothing leaves your browser

Honest note: files that are already compressed, or hold no large images, shrink little —
the savings come from big embedded photos.

Free for one file up to 10 MB. PackFit Pro (optional one-time purchase): batch, unlimited
file size, and image quality/dimension controls. License key works offline.
