Compress PDF to 1 MB
Shrink a PDF to under 1 MB for email attachments and general uploads with a 1 MB cap. Free and private — pages are re-rendered at progressively lower quality in your browser until the file fits, never uploaded.
To compress a PDF to 1 MB, this tool re-renders the pages at progressively lower quality and resolution until the file drops under 1 MB. Drop your PDF and it targets 1 MB automatically. If 1 MB isn't reachable, it delivers the smallest version it can and tells you the exact size rather than faking success. Processing happens locally in your browser.

Frequently asked questions
How do I compress a PDF to 1 MB?
Load your PDF here and it steps the image quality and resolution down until the file is under 1 MB, then lets you download it. You'll see the final size first.
Will the text stay selectable?
No — to hit a strict size target, pages are re-rendered as images, so text becomes part of the image. Keep the original if you need selectable text.
What if the PDF can't reach 1 MB?
Very long or dense PDFs may not fit 1 MB while staying readable. In that case the tool shows the smallest size it achieved instead of claiming success.
Is my PDF uploaded?
No — compression runs entirely in your browser.
