Under the Hood

Compression works by downscaling embedded images to a target DPI and applying efficient encoding. You can choose between different quality levels depending on whether you prioritize smaller size or higher fidelity. Text and vector elements remain sharp regardless of the compression level.

Popular Scenarios

  • Email attachments

    Shrink a PDF below common email size limits so it can be sent without a file-sharing link.

  • Web publishing

    Reduce file size for faster downloads when hosting PDFs on a website.

  • Storage savings

    Compress archived documents to free up disk space without losing important content.

Frequently Asked Questions

How much smaller will my file be?

It depends on the content. PDFs with many high-resolution images can often be reduced by 50-80%. Text-heavy documents see smaller reductions.

Will compression make text blurry?

No. Text and vector graphics remain crisp. Only embedded raster images are optimized.

Can I compress a file that is already compressed?

You can try, but the size reduction will be minimal if the file has already been optimized.
