    Keep text mode optimizes the PDF structure without touching the content, so savings are usually modest. Strong mode redraws each page as a compressed image — very effective for scans and photo-heavy files, but the text is no longer selectable or searchable.

    If the compressed file would be larger than the original, the original is kept.

    Frequently asked questions

    Which mode should I use?

    Try Keep text first. If the file is still too large — typically scanned documents — use Strong.

    Why can't I select text after strong compression?

    Strong mode turns each page into an image to save space. Keep the original if you need searchable text.

    Are my files uploaded?

    No. Compression runs in your browser.
