Shrink a PDF to a target size

Perfect for email and upload limits. Pages are re-rendered as compressed images: layout and page count stay identical, but text is no longer selectable and fine detail is reduced.

    Target size: MB
    Target mode automatically finds the best quality that fits under your limit — it tries high quality first and only steps down as far as needed.

    Frequently asked questions

    Are my files really private?

    Yes. Everything runs in JavaScript inside your browser tab. Your files are read into memory on your own device, processed there, and never uploaded, stored, or transmitted anywhere. Close the tab and they're gone. You can even load this page, disconnect from the internet, and it still works.

    What's the difference between Compress and Shrink?

    Compress is lossless: it repacks the PDF's internal structure so nothing about the content changes — same text, same image quality. Savings are modest but free. Shrink is lossy: it re-renders pages as compressed images to hit a target file size. It saves far more space, but text stops being selectable and fine detail is reduced.
