Reduce PDF file size

PDF files can contain structural objects, streams, metadata, and other internal data that contribute to file size. Structural optimization can remove some unnecessary overhead and produce a smaller PDF.

Does PDF compression reduce image quality?

PickSutra’s current PDF compressor uses lossless structural compression. It does not aggressively recompress embedded images, so the tool is not intended for maximum image-size reduction. PDFs containing large photographs or scanned images may therefore see limited size reduction.

When should you compress a PDF?

Compressing a PDF can be useful before uploading a document to a website, attaching it to an email, storing it online, or sharing it with someone when the original file is larger than necessary.
