Why Compress a PDF?
Large PDFs are slow to email and can be rejected by upload limits. Compressing a PDF reduces its size so it sends faster and stores easily, while keeping the document readable and sharp.
Smaller File Size
Fit under email and upload limits without splitting the document.
Quality You Control
Pick the balance between file size and visual quality that suits you.
Processed Locally
Compression runs in your browser, so nothing is uploaded anywhere.
Compress PDF FAQ
Will compressing reduce the quality of my PDF?
It depends on the level you pick. 'Less' keeps high quality with modest savings, 'recommended' balances size and clarity, and 'extreme' shrinks the most by lowering image quality. Text usually stays crisp at every level.
How much smaller will my file get?
Savings depend on the content. PDFs full of high-resolution images shrink the most, often by half or more, while text-only documents are already compact and change less. The tool shows the exact percentage saved after it runs.
Is my file safe when I compress it?
Yes. The entire process happens in your browser on your own device. Your PDF is never uploaded, so sensitive files like invoices and reports stay completely private.
