Réduire la taille du fichier PDF en ligne

Large PDFs can be slow to email or upload. This tool optimizes the internal structure and removes unnecessary metadata to make the file smaller.

Pourquoi compresser ou nettoyer les fichiers PDF avant de les partager ?

PDF documents often contain hidden metadata including the author's name, software used to create the file, creation and modification dates, and even embedded comments or annotations. When you email a PDF or upload it to a website, this information becomes publicly visible.

Large PDF files can also be problematic — they exceed email attachment limits, take longer to upload, and consume more storage space. Our browser-based PDF tools compress, merge, and clean your documents instantly without uploading anything to external servers.

Quelles métadonnées sont supprimées des PDF ?

Our PDF metadata remover strips author names, company information, creation dates, modification history, software identifiers, and any embedded comments. The document content remains unchanged; only the tracking information is removed for your privacy.

Est-il sûr de traiter des PDF dans le navigateur ?

Absolutely. Unlike online PDF converters that upload your files to remote servers, our tools run entirely in your browser using WebAssembly technology. Your documents never leave your device, ensuring complete confidentiality for sensitive contracts, resumes, or personal documents.
