Reduce a PDF to 1 MB
ShrinkBeam searches for a practical combination of image quality and resolution that approaches the selected 1 MB target. The work happens directly in your browser.
Can every PDF be compressed below 1 MB?
No. Long documents, scans and image-heavy PDFs may require substantial quality reduction and sometimes cannot reach exactly 1 MB. In that case ShrinkBeam aims for the smallest practical result.
How to make a PDF smaller than 1 MB
Select the PDF, keep the 1 MB target, start compression and save the result. If the document can be reduced sufficiently, the downloaded file will fit the target while your original remains untouched.
