Frequently asked questions

Does compressing upload my PDF?

No. PDFSnap compresses PDFs entirely in your browser. Your file never leaves your device — not even temporarily.

Will compression reduce quality?

Image-heavy PDFs are re-rendered as JPEG pages. Balanced keeps better quality; Maximum produces the smallest file. Text-only PDFs may not shrink much.

Is PDF compression free?

Yes. No account, subscription, usage limits, or watermarks.

Why is my compressed file the same size?

If the PDF is already optimized or mostly text, re-compression may not help. PDFSnap returns the original when the output would be larger.

How much can PDFSnap reduce a PDF file size?

Typical image-heavy PDFs see 40–80% file size reduction. Results vary depending on how the PDF was originally created and its content type.

Can I compress a PDF for email?

Yes. Use Maximum compression mode to get the file under 10 MB or 25 MB for email attachments. All compression happens locally — no upload required.
