Compress PDF to 1MB — Free Browser-Based Tool
Many online portals, job application forms, and government websites have a strict 1MB PDF upload limit. Our compressor gives you three compression levels to hit that target. Maximum Compression typically reduces PDFs by 70–85%, bringing most documents well under 1MB. Your file never leaves your device.
Recommended setting: Maximum Compression — To reach 1MB, use Maximum Compression first. If the result is still over 1MB, the PDF likely has many high-resolution images. Try splitting it into sections.

Frequently Asked Questions
Can I compress any PDF to under 1MB?
Most single-document PDFs compress to under 1MB with Maximum Compression. Very large PDFs (many pages or embedded high-resolution images) may not reach 1MB — in those cases, try splitting the PDF into smaller sections.
Why do some forms require a PDF under 1MB?
Government portals, HR systems, and application forms often have strict file size limits to reduce server storage costs and upload time. Compressing your PDF is the standard way to meet these requirements.
Does Maximum Compression ruin the PDF?
The PDF will look very slightly softer at 100% zoom, but all content remains fully legible. For form submissions and uploads, the quality is always acceptable.
