FAQ
How much can the file size be reduced?
Depending on internal metadata and image resolutions, you can typically expect a 30% to 70% reduction for scanned files.
Will text become unreadable after compression?
Standard compression preserves text clarity. For maximum compression, heavy raster texts might blur slightly. We suggest using Standard compression for invoice documents.
What is the maximum allowed upload size?
You can upload a single document up to 100MB.
Is it safe to upload confidential files?
Yes. Because the processing occurs within your browser memory local space, there is zero network exposure of document contents.
Can I compress encrypted PDFs?
No. Please decrypt the protected PDF using our Unlock tool first, then proceed with compression.
