About Compress PDF to 1MB
Who it is for
People reducing scanned documents, brochures or reports for portals and email systems that impose a 1MB attachment limit.
What it helps you do
Choose a lower resolution and quality, select the PDF, review the output size, and download or recompress it with different settings.
How local compression is different
Processing stays on your device instead of sending confidential pages to a cloud service. Pages are rendered as images, so the output is best for visual documents and its text will not remain searchable.
What to do next
Choose a file in the tool above, review the settings, then download the result. You can also use the full compressor guide for format details and tips.
