Frequently Asked Questions
Q.01Why did my PDF file size barely decrease after compression?
If your PDF contains mostly digital text, vector charts, or was already optimized when saved from Word or Canva, it is already as small as possible. FILPDF never compresses files in a way that would ruin text clarity.
Q.02Will compressing a PDF make text or drawings blurry?
No. Our compression selectively optimizes large embedded photos and background images. Text fonts, line art, and vector graphics remain crisp and clear at any zoom level.
Q.03Which compression level should I choose for email attachments?
Choose "Recommended Compression". It reduces file size by 50% to 70% while keeping text and photos looking sharp on screens and standard office printers—easily fitting under typical 25MB email limits.
Q.04How can I get the maximum file reduction for a scanned PDF?
Scanned documents contain full-page images. Choose Extreme Compression for an immediate 70% to 85% size reduction. If your document is black and white, converting to Grayscale PDF first removes extra color channels for maximum byte savings.
