PDF 서명

This places an image of your signature on the page — it doesn't create a certified digital signature (no PKI certificate or signing audit trail). For contracts that legally require certified e-signatures, use a dedicated signing service.

내용 가리기

No redactions yet.

Pages with at least one redaction are converted to a flat image before download, so hidden text and objects underneath can't be recovered — not just visually covered. Those pages lose their selectable/searchable text layer.

PDF 압축

Scanning for compressible images…

Only JPEG images inside the PDF are recompressed — text and vector graphics stay untouched and fully searchable. Other image types (PNG, scanned black-and-white formats) aren't recompressed yet, and a PDF with little or no image content may not shrink much.

PDF 양식 작성

Fields are filled directly on the page preview — click into a box, type, check, or choose an option. Everything happens in your browser; the PDF is never uploaded.

Extracting text…

Feel free to edit the text before copying — nothing here is sent anywhere. Only real, selectable text is extracted; scanned/image-only pages won't produce text here — try VitePDF's OCR tool for those.

두 PDF 비교

This is a visual comparison — each page is rendered as an image and checked pixel by pixel, so it catches text, layout, and image changes alike, but it doesn't diff the underlying text word-for-word. Everything happens in your browser.

PDF 복구

Repair tries two things: first, rebuilding the file's internal structure while keeping everything editable and searchable — this recovers most real-world corruption. If the damage is too severe for that, it falls back to recovering whatever individual pages can still be read as images.

PDF에서 이미지 추출

Scanning for images…

This version pulls out JPEG images (the most common kind in scanned and photo-heavy PDFs). Other embedded formats — PNG, indexed color, scanned black-and-white — aren't extracted yet.

PDF 메타데이터 편집

Leave any field blank to remove that piece of information entirely. Everything else about the file — pages, text, formatting — stays exactly as it was.

PDF 소리 내어 읽기

Feel free to edit the text before playing — useful for skipping over garbled extraction. Reading happens entirely in your browser using its built-in voice; nothing is uploaded.

빈 페이지/중복 페이지 찾기 및 제거

Blank pages are detected by how much of the page has any content at all. Duplicates are found with a pixel-by-pixel visual comparison against every earlier page, so near-identical pages are caught even if they're not next to each other.

인쇄용 페이지 합치기

Each original page is placed as real vector content, not a flattened image — text inside stays sharp when printed, though it's too small on the sheet to select or search afterward.

그레이스케일로 변환

Every page is converted to a flat, black-and-white image, so the result is no longer searchable/selectable text, and text-heavy files may end up larger, not smaller. If you just need a grayscale print, choosing "Black & white" in your printer's own dialog usually gives a sharper result without converting the file at all — use this tool when you need an actual grayscale file to share.

북마크 / 목차

No bookmarks added yet.

Adds a bookmarks panel that most PDF readers show down the side, linking straight to each page. This version supports one flat list (no nested sub-sections yet). Saving replaces any bookmarks the PDF already has.
