Compress PDF for Email vs Optimize PDF for Email: which should you use?

Both reduce PDF size for email, but they optimise differently: aggressive compression for the smallest attachment, versus balanced optimisation that protects image quality.

When to use Compress PDF for Email

Choose Compress PDF for Email when the priority is getting under a mailbox limit and some image softening is acceptable.

Reduce PDF file size to fit email attachment limits while maintaining readability.

When to use Optimize PDF for Email

Choose Optimise PDF for Email when the document is client-facing and photos, plans or charts must still look professional.

Shrink your PDF files specifically for email while keeping them looking professional.

The verdict

Hard size pressure: compress. Quality-sensitive documents: optimise.

Both tools run inside your session, are UK GDPR-aligned, and every uploaded file is purged within 1 hour under our non-persistence guarantee.

Frequently asked questions

Will body text stay readable?
Yes — text is not rasterised, so it stays sharp regardless of image downsampling.
What if I need a specific ceiling like 2MB?
Use Compress PDF Under 2MB, which targets that hard limit directly.
Does compression remove metadata?
It may drop embedded previews; use the Metadata Scrubber if removal must be guaranteed.
