PDF 페이지 재정렬 및 추출 도구

Reorder, remove, or extract pages from any PDF instantly — all in your browser. No upload, 100% privacy.

이 도구가 하는 일

This PDF Page Reorder & Extract tool lets you load a PDF file and manipulate its pages directly in your browser memory. You can visually reorder pages, select pages to extract into a new file, and remove unneeded pages. Everything happens locally — the file never leaves your machine. That keeps your documents private and speeds up the workflow.

Client-side Processing

PDF bytes are read and processed entirely in the browser using modern libraries. No file uploads, no server-side storage — perfect for sensitive documents.

Drag & Drop Reordering

Arrange pages with drag-and-drop thumbnails, or use quick buttons to move pages left/right. Visual reordering makes it fast to reorganize any document.

Extract & Download

Select pages to extract into a new PDF. After you confirm, the new PDF is created locally and downloaded automatically — no server round trips.

Small & Fast

Code is optimized to lazy-load heavy modules only when needed. The UI is minimal and built for performance to keep First Contentful Paint fast.

Accessibility First

Keyboard-friendly controls, clear labels, and ARIA attributes make the tool usable for everyone, including people using assistive technologies.

No Account Required

Use the tool immediately — no sign ups, no tracking, and a straightforward UX that prioritizes privacy and speed.

작동 방식 — 간단하고 안전하게

  1. Upload or drop a PDF file using the upload area. The file is read into browser memory as a binary array.
  2. Reorder pages with drag-and-drop or arrow controls. Page indices update immediately so you can track order changes.
  3. Create a new PDF client-side by copying pages in the chosen order and saving them into a new file blob.
  4. Download instantly — the resulting PDF is provided as a download link and is never uploaded to any server.

Under the hood we use a lightweight PDF library (for example pdf-lib) and render thumbnails with a small canvas. Heavy modules are loaded only when the user uploads a file to keep the landing page fast.

단계별: 도구 사용 방법

1 — Click the upload area or drag a PDF file into the page. Supported files: .pdf.

2 — Use the drag handle to move a tile, or click a page for precise movement.

3 — When ready, click Download PDF. The download begins immediately and your original file remains unchanged on your device.

개인 정보 보호 및 보안 — 클라이언트 측 처리의 중요성

Security and privacy are central design principles for this tool. Because every operation happens in the browser, your PDF file is never transmitted to a third-party server. That means:

  • No uploads: the file is read locally and processed in memory.
  • No logs: there’s nothing to store on servers, so there are no retained copies.
  • Temporary data: browser memory and temporary object URLs are released after download.
  • Open behavior: the code can be audited — we encourage transparency for privacy-minded users.

성능 및 구현 팁

To keep the page fast and score well on Lighthouse, follow these best practices:

  • Lazy-load heavy libraries: import pdf-lib only when the user uploads a file (`await import('pdf-lib')`).
  • Use Web Workers: move intensive PDF processing off the main thread to keep UI responsive.
  • Optimize thumbnails: generate low-res thumbnails for quick preview and only render high-res if requested.
  • Limit memory use: revoke object URLs and release arrays after download to avoid excessive memory consumption on mobile.
  • Minimize client script size: keep the landing page free of heavy bundles and delay analytics or ad scripts until after the user interacts.

문제 해결 및 실용 팁

Browser compatibility
Modern browsers (Chrome, Firefox, Edge, Safari) support the APIs required. Mobile browsers work, but large files may be memory-heavy — prefer desktop for very large PDFs.
Large PDFs
For very large PDFs (hundreds of pages), consider splitting the job or using the extract-by-range feature to process smaller chunks to reduce memory pressure.
Printing & page sizes
Page sizes and orientation are preserved when copying pages. If you require reflow or resizing, use a dedicated PDF editor before reordering.

자주 묻는 질문

Is my PDF uploaded to the internet?

No. All processing is done client-side in your browser. The file never leaves your device unless you manually upload it somewhere else.

What file types are supported?

This tool supports standard .pdf files. Encrypted or password-protected files cannot be processed unless you decrypt them locally first.

Can I use this on mobile?

Yes — the interface is responsive. For very large files, desktops handle memory better.

Will the page keep a copy of my file?

No — the tool does not send or store files on a server. Temporary memory and object URLs are released promptly after download.

What happens if the page crashes?

If the browser crashes, the file may remain unchanged on disk. We recommend saving important files before processing very large PDFs.
