Compress PDF: what it is for
Compressing a PDF is essential for emailing it, uploading it to portals with a size limit or saving storage. CruzForge analyses every embedded image and only reduces the ones that are heavier than necessary, the way professional desktop compressors do.
Instead of several hard-to-understand compression levels, a single “maximum without quality loss” mode is applied and you are shown the exact result before downloading.
Frequently asked questions
How much smaller does a PDF get?
It depends on the content. PDFs with many photos (catalogues, colour scans, slide decks) usually shrink by 40% to 80%. Text-only PDFs are already light and barely change.
Is quality lost?
Photos are reduced to a resolution that is ample for screens and normal printing and recompressed at high quality. Text and vector drawings stay exactly the same.
Why doesn't my PDF get smaller?
If it was already optimized, or is almost all text, there is nothing heavy to reduce without hurting quality. In that case the tool tells you so instead of degrading the document.
Can I compress a PDF to send it by email?
Yes, that is the most common use: many mail providers limit attachments to 20–25 MB.
