OCR PDF text search

Scans every page (including scanned/image-only pages with no selectable text) so you can search for a word or phrase.

PDF to Word

Extracts the real text where the PDF has it, and runs OCR automatically on scanned/image-only pages. Works best for simple, single-column documents — complex layouts, tables, and multi-column text won't be preserved exactly.

PDF to PowerPoint

Each page becomes one slide, rendered as a full-page image — layout, fonts, and graphics come out exactly as they look in the PDF. Runs entirely in your browser.

PDF to Excel

Reconstructs rows and columns from the PDF’s own text spacing, and runs OCR automatically on scanned/image-only pages. Works best for simple, clearly-aligned tables — free-form text near a table may get split oddly.

PDF to JPG

Each page becomes a .jpg image. Runs entirely in your browser — nothing is uploaded. Multiple pages are zipped together for download.

JPG to PDF
HTML to PDF

PDF to HTML

Produces one self-contained .html file — an image of each page with an invisible text layer on top, so it looks exactly like the PDF but the text stays selectable, searchable (Ctrl/Cmd+F), and copyable. Runs entirely in your browser.

Kako zaštititi PDF lozinkom online

  1. Odaberite PDF koji želite zaključati.
  2. Unesite lozinku koju ljudi moraju znati da bi ga otvorili.
  3. Po želji označite „Onemogući ispis” i/ili „Onemogući kopiranje” kako biste ograničili što se može raditi nakon otvaranja.
  4. Kliknite gumb Zaštiti PDF i preuzmite kopiju zaštićenu lozinkom.

Zašto koristiti VitePDF

  • Stvarno AES-256 šifriranje — datoteci je nakon toga zaista potrebna vaša lozinka za otvaranje u bilo kojem čitaču PDF-a.
  • Neobavezna ograničenja dozvola (bez ispisa, bez kopiranja) vrijede i za osobe koje imaju lozinku.
  • Nije potreban račun, dokumentu se ne dodaje vodeni žig.

Često postavljana pitanja

Radi li ovo sa svakim čitačem PDF-a ili samo s VitePDF-om?

Sa svakim uobičajenim čitačem PDF-a — Adobe Acrobat, Preview, PDF preglednicima u pregledniku i tako dalje. Lozinka je dio stvarnog šifriranja datoteke, a ne posebnost ove web stranice.

Mogu li kasnije ukloniti lozinku?

Da — upotrijebite VitePDF alat Otključaj PDF s istom lozinkom kako biste dobili nezaštićenu kopiju.

Je li moja datoteka sigurna pri korištenju ovog alata?

Vaša datoteka i lozinka prenose se na poslužitelj za obradu — poput svakog online alata za zaštitu PDF-a koji koristi stvarno šifriranje — i ne pohranjuju se nakon obrade.
