About the Compress PDF tool

100% private: This tool runs entirely inside your web browser. Your files are never uploaded to a server — they never leave your device. That makes it faster, and it means your documents stay completely confidential.

How compression works

Tallywise reduces file size primarily by re-encoding embedded images at a lower resolution and quality level that you control, then rebuilding the PDF. Text-heavy documents also benefit from stream optimization.

When to compress

Compress when a PDF is too large to email (many inboxes cap attachments around 20–25 MB) or when a website form rejects your upload for being too big.

Frequently Asked Questions

Will compression blur my text?

No. Text and vector graphics stay crisp. Size savings come mainly from images, so scanned or image-heavy PDFs shrink the most.

How much smaller will my file get?

It depends on the content. Image-heavy or scanned PDFs can shrink dramatically, while documents that are already mostly text may only reduce a little.
