Before you start
- Keep the original PDF; compression is not a reversible edit.
- Start with Balanced unless the recipient specifies a size or print-quality requirement.
MV ToolsPDF tool
PDF Compressor Online
Compress PDF files with PDF processing and download a smaller temporary PDF.
Before you compress
Choose a profile for the way the PDF will be used next, then open the result before replacing the original.
- Start with Balanced for ordinary email and portal uploads.
- Check small text, tables, signatures, photos, and any barcode or QR code after compression.
- Keep the original: text-only or already optimized PDFs may not get smaller.
One PDF up to 100 MB is processed temporarily on the server. The default cleanup window is 30 minutes; download results promptly.
How to Compress a PDF Without Losing ReadabilityChoose compression deliberately
Check the result
- Open image-heavy and text-heavy pages at normal reading size.
- Compare page count, readability, and the final file size before sharing.
Know the limit: Already optimized or mostly text PDFs may barely shrink, and stronger profiles can soften images.

Common Use Cases
- Reducing scanned PDF files before uploading or emailing
- Making image-heavy PDF reports smaller for sharing
- Testing screen, ebook, printer, and prepress compression profiles
How Data Is Handled
Uploaded PDFs and compressed PDFs are processed temporarily on the server and are cleaned up automatically after the retention window.
FAQ
Which compression level should I choose?
Balanced is a good default. Smallest file creates stronger compression, while high quality and maximum quality preserve more visual detail.
Will every PDF become smaller?
No. Scanned or image-heavy PDFs usually shrink the most. Already optimized or text-only PDFs may not shrink and can sometimes become slightly larger.
Are uploaded PDFs stored permanently?
No. Uploaded and compressed PDFs are temporary and are cleaned up automatically.
