Compress PDF to 1MB

1. Upload your PDF (up to 50 MB).
2. The compressor automatically targets 1 MB or under.
3. Download the compressed PDF.

1 MB is generous — most PDFs fit easily with minimal compression. Quality stays essentially identical to the original.

1 MB is the cap on many platforms (email systems, marketplaces, government portals). Most PDFs fit easily at 1 MB with minimal compression, preserving high-quality images and sharp text.

The compressor analyzes the PDF and iterates image quality until the output is 1 MB or under. Text is preserved losslessly; images retain high resolution.
