压缩 PDF — Frequently Asked Questions

How much can I reduce my PDF size?▼

Typically 30–80% reduction, depending on how many images are in the PDF. Text-only PDFs compress less.

Will compression make my PDF blurry?▼

We use smart compression that reduces file size while keeping text crisp and images acceptably clear.

Can I compress a PDF for email attachments?▼

Yes — most email clients have a 10MB or 25MB limit. Compressing your PDF first ensures reliable delivery.

Does compression remove any content?▼

No pages, text, or images are removed. Only internal data overhead is reduced.

Can I compress the same PDF multiple times?▼

You can, but the gains diminish after the first compression. Run it once for the best result.
