Podepsat PDF

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.

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.

Komprimovat PDF

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.

Vyplnit formuláře PDF

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.

Porovnat dva PDF

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.

Opravit PDF

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.

Extrahovat obrázky z PDF

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.

Číst PDF nahlas

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.

Najít a odstranit prázdné/duplicitní stránky

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.

Spojit stránky pro tisk

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.

Převést na odstíny šedi

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.

Záložky / obsah

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.
