Is compressing a PDF free?

Yes, completely free with no file limits beyond the upload size cap.

Will the text still be selectable/searchable?

Yes. Compression only recompresses embedded images - text and vector content are left untouched.

How much smaller will my PDF be?

It depends heavily on the source - PDFs with large embedded photos or scanned pages shrink the most, often 50-90%. A PDF with mostly text may barely change.

PDF Compressor

Reduce PDF file size online, free, by recompressing embedded images.

Compression works by downsampling and recompressing embedded images inside the PDF - text and vector content stay sharp. Scanned/image-heavy PDFs shrink the most; text-only PDFs may barely change.
