How does PDF compression work?

PDF compression for Dropbox uses WebAssembly technology to process your files directly in the browser. Unlike cloud services, no file is sent to a server. The algorithm reduces embedded image weight, removes unnecessary metadata, and optimizes the internal PDF structure. The result: a lighter file, perfect for Dropbox, while preserving text readability and visual quality of graphic elements.

Compression Quality Levels

Light

20-40% reduction. Ideal for documents with few images. Quality nearly identical to original.

Medium

40-60% reduction. Good balance between size and quality. Recommended for most uses.

Maximum

60-90% reduction. Perfect for email or messaging attachments. Images are more compressed.

Privacy & Security

When you compress a PDF for Dropbox with FreeConversion, your files never leave your device. Processing happens entirely in your browser using WebAssembly — no data is sent to a remote server. This is the ideal solution for sensitive documents: contracts, resumes, invoices, bank statements. Unlike other online tools, we never store, read, or analyze your files.

Dropbox file size limit: 2 Go (gratuit)
