How do I compress a PDF to 1MB?

Upload your PDF, click the "1 MB" preset, and click Compress. The tool automatically finds the optimal quality level to bring your file under 1MB.

Why would I need a PDF under 1MB?

Job application portals, university admissions, HR systems, and many email servers impose a 1MB file size limit. This tool lets you meet those requirements while keeping your document readable.

Is there a file size limit for the input PDF?

You can compress PDFs up to 150MB. Since all processing happens in your browser, very large files may take more time depending on your device.

Will my compressed PDF still be readable?

Yes — the tool uses binary search to find the highest quality that still meets your target, so the result is as readable as possible within the size constraint.
