Frequently asked questions
Will compression blur text?
Text-based PDFs usually stay sharp. Photo-heavy scans may show slight image softening — that is how most size savings appear.
How small can a PDF get?
Depends on content. Already-optimized digital PDFs shrink little; scanned 300dpi packs often drop substantially.
Is Compress PDF safe for legal documents?
Files never upload to our servers. Always keep an archival original if your policy requires an uncompressed master.
Compress vs Reduce File Size — which should I use?
Start with Compress PDF. Use Reduce File Size when a portal still rejects the file and you accept stronger image downsampling.
Does this work offline?
After the page loads, processing runs in the browser. Offline use depends on whether assets are already cached by your browser.
