📁 Compress a PDF
Our free online PDF compressor lets you instantly reduce the size of your documents. Choose between light, medium, or strong compression depending on your needs, for files that are easier to share by email or store, while maintaining optimal visual quality.
Why use our PDF compressor?
A PDF file that is too large can quickly become a problem, whether you need to send it as an email attachment or upload it to an administrative portal. Our online tool adapts to your needs with three smart compression modes:
1. Light Compression (Maximum Quality)
Ideal for documents containing a lot of text and a few images. It slightly reduces your document size while keeping visual quality strictly identical to the original.
2. Medium Compression (Perfect Balance)
The best compromise for everyday use. It significantly reduces file size by removing redundant data and slightly lowering image resolution. The result is perfect for web use.
3. Strong Compression (Minimum Size)
Designed for extremely large files or submissions to platforms with strict size limits (for example, to easily meet KB or MB limits). This mode maximizes graphic optimization while keeping your document perfectly readable.
4. Total Privacy:
Your files are processed quickly and then automatically deleted from the server.
