Qu'est-ce que Diviser un PDF ?

PDF Split decoupe un PDF en fichiers plus petits. Divise par page, par plage ou par chapitre. Rien n'est envoye. Depose un PDF et marque les points de coupure. L'outil cree un fichier par plage. Tout tourne dans ton navigateur. Le contenu des pages reste identique dans chaque morceau. Polices, graphiques vectoriels, liens et champs de formulaire sont conserves. Le fichier source ne va jamais sur nos serveurs. Tape 1-3, 5, 7-10 ou 12. Le mode page par page donne un PDF par page. Les avocats extraient des pages de pieces de longs PDF. Les comptables separent des dumps fiscaux multi-clients en dossiers par client. Les editeurs decoupent des chapitres de livre. Les etudiants recuperent les pages assignees d'un PDF de manuel. Les equipes IT decoupent de gros rapports sous la limite de 25 Mo de Gmail.

Quand dois-je utiliser cet outil ?

  • Extraire une seule page de contrat signé d'un long accord
  • Séparer les chapitres d'un livre scanné en fichiers PDF individuels
  • Isoler uniquement les justificatifs de dépenses d'un export bancaire groupé
  • Diviser un PDF multi-factures en un fichier par client

Questions fréquemment posées

La division envoie-t-elle mon PDF quelque part ?

No. WikiPlus PDF Split runs entirely inside your browser tab without transmitting a single byte of your document to any server. When you open a PDF file in the tool, the browser reads its bytes from your local file system into tab memory using the FileReader API. The pdf-lib library parses the document structure and extracts the requested pages — all of this happens within the same sandboxed browser process on your own device. The resulting output PDFs are assembled in local memory and delivered to your downloads folder through the browser's native save mechanism. No copy of your file is created on a WikiPlus server at any point. No filename, file size, page count, or content metadata is logged in any analytics or monitoring system. This matters for the types of documents people most commonly need to split: signed NDAs and contracts contain confidential commercial terms; medical records contain protected health information; court filings may be under seal; bank statements list account numbers. Uploading these to a server-based splitter creates a record on a third-party system that you cannot independently audit or retract. WikiPlus eliminates that risk entirely by keeping every operation local. You can verify this yourself: open your browser's developer tools, switch to the Network panel, and watch for outbound requests while splitting a PDF. You will see no network request that carries your file data. For additional certainty, load the page once to cache the page assets, then disconnect your device from the internet and run the split. It completes successfully in fully offline mode, which proves nothing depends on a server connection. Tip: after downloading the split output files, verify that each piece opens correctly in your default PDF viewer before deleting or archiving the source file.

Comment spécifier des plages de pages personnalisées ?

WikiPlus PDF Split accepts page ranges in a simple comma-separated syntax that covers all practical splitting scenarios. Type your ranges into the custom-range input field and separate each range with a comma. A hyphenated pair like 1-5 extracts pages one through five as a single output file. A single number like 8 extracts just page eight on its own. A combination like 1-3, 5, 8-10, 12 produces four separate output PDFs: one containing pages one through three, one containing only page five, one containing pages eight through ten, and one containing page twelve. Page numbers follow the document's visible sequence starting from page one — they correspond to the numbers shown in the PDF viewer's page counter, not to the internal PDF object indices, which are invisible to readers. If you specify a range that exceeds the document's total page count, the tool flags the invalid range in red before the split runs so you can correct it without wasting time. Open-ended ranges (for example, 5- meaning page five to the end) are not supported in the current release — you must specify both endpoints. For the common task of extracting a contiguous block from the middle of a document, type the first and last page numbers of that block separated by a hyphen. For extracting a handful of non-contiguous pages, list them individually separated by commas. The split creates one output file per range entry, preserving all text layers, fonts, images, hyperlinks, and annotations from the source pages exactly as they appeared in the original. Tip: for documents where pages are logically grouped by section (chapters, exhibits, departments), note the first and last page number of each section before typing the range strings to avoid off-by-one errors.

Puis-je diviser un PDF protégé par mot de passe ?

Not directly in its encrypted state. If the source PDF has a user-open password, the tool cannot read the page content because the content streams are encrypted at the byte level — decryption requires the password key, and without it the page data is unreadable ciphertext that cannot be split into meaningful output. If the source PDF has an owner password (a permissions restriction preventing printing, copying, or editing) but no user-open password, some PDF readers allow opening the file normally while blocking certain viewer actions, and the WikiPlus splitter can often read and split these files because owner restrictions are viewer-enforced conventions, not true content encryption. For files with a user-open password you know, the correct workflow is two steps: first, use WikiPlus PDF Unlock with the password to produce a decrypted copy of the file — this runs locally in your browser and does not transmit the password or file contents anywhere. Second, load the unlocked copy into WikiPlus PDF Split and proceed with your chosen split mode. This two-step workflow is intentional. WikiPlus never attempts to bypass encryption using brute-force or dictionary attacks — the tool is designed only to process documents you are authorized to open. The password you enter in PDF Unlock is consumed immediately in browser memory to decrypt the local file copy and is never transmitted, stored, or logged. The resulting unlocked copy is saved only to your device. If the source file lives on a shared network drive or cloud folder, the original encrypted copy in that location remains untouched — only your local decrypted copy is affected. Tip: after unlocking, save the decrypted copy to a location you control and remember to delete it when the split task is complete if you do not want an unencrypted copy persisting on your device.

Le splitter PDF est-il gratuit ?

Yes, completely and permanently. WikiPlus PDF Split is free with no registration, no email verification, no credit card, no trial period, and no hidden upgrade gate behind a free tier. Every feature of the splitter is available from the first visit without creating an account: split by every page, split by fixed intervals (every N pages), split by custom page ranges, and download all outputs as a single ZIP archive. There are no daily, weekly, or monthly usage caps. There is no file size limit imposed by a paywall — the practical upper limit is your browser's available RAM, not an artificial restriction. Output files are clean PDFs with no WikiPlus watermarks, no added branding pages, and no embedded metadata attributing the split to this tool. The tool is sustained by simple display advertising shown on the page — the ads fund free operation without restricting the tool's functionality for any user on any visit. This model differs from competing PDF splitters that offer a free tier with limitations: some cap daily splits at two or three files, some restrict the file size on free plans to 10–25 MB, and some add watermarks to the first or last page of each output. WikiPlus imposes none of these restrictions. A student splitting a 400-page textbook PDF into individual chapters, a paralegal splitting a discovery PDF into per-exhibit files, and a small business owner splitting a multi-invoice PDF into per-client files all get the same unlimited access. Tip: for PDF files larger than 50 MB, consider running WikiPlus PDF Compress on the source file first — a smaller source PDF splits faster and produces smaller output files that are easier to email or upload to document portals.
