    How it gets under 2 MB
    _ □ x

    Most of a large PDF is its images: scanned pages, photos, screenshots. CrunchBox redraws them as JPGs at a lower quality and, when needed, with fewer pixels.

    It starts gentle and measures the result. If the file is still over 2 MB, it works out how much more the images have to give and moves to a stronger setting. It stops at the gentlest setting that fits, so your PDF is not compressed harder than the limit needs.

    Text, fonts, and drawings are not touched. Text stays sharp, and you can still select and search it.

    Sometimes 2 MB is out of reach. The tool tells you, and tells you which case it is:

    • The images are already as small as they go. You get the smallest version it could make, with its size
    • The text, fonts, and drawings alone are over 2 MB. This tool only shrinks images, so a long text-heavy PDF may not fit

    When a tight limit takes images down far enough that small text in a scan may blur, the result says so. Open the file and check it before you send it.

    What 2 MB means here
    _ □ x

    Sites count a megabyte two ways: 1,000,000 bytes or 1,048,576 bytes. CrunchBox uses the smaller one, so "under 2 MB" means 2,000,000 bytes or less. That fits a 2 MB limit whichever way the site counts.

    Your PDF never leaves your device. Loading, compressing, and download all happen in your browser, and nothing is uploaded. That matters most for the documents people usually need to shrink: IDs, contracts, tax forms, medical records.

    This is why we run entirely in-browser: if we can't touch your files, we can't lose them, leak them, or profile them.
