Does compressing a PDF reduce its quality?

PDF Mavericks uses smart compression that targets redundant image data and metadata. For most documents, the visual quality is indistinguishable from the original. You can choose compression level to balance size vs. quality.

Is there a file size limit for the PDF compressor?

Our compressor supports files up to 100MB. All processing happens in your browser — your file is never uploaded to any server.

How much can I reduce a PDF file size?

Typical size reductions range from 30% to 90% depending on the content. PDFs with many high-resolution images see the greatest savings.

Is the PDF compressor really free?

Yes. The compressor is completely free with no registration, no daily limits, and no hidden fees.

Can I compress multiple PDFs at once?

Currently you can compress one PDF at a time. Upload your file, choose your compression settings, and download the result instantly.
