OCR PDF text search

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

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

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

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

PDF to JPG

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

PDF to HTML

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 pretvoriti PDF u sive tonove online

  1. Odaberite PDF datoteku iz koje želite ukloniti boju.
  2. Odaberite standardnu ili visoku rezoluciju, ovisno o tome koliko oštar treba ostati tekst i koliko mala treba biti datoteka.
  3. Kliknite Pretvori u sive tonove.
  4. Preuzmite crno-bijeli rezultat.

Zašto koristiti VitePDF

  • Korisno kada nekome želite dati (ili arhivirati) pravu datoteku u sivim tonovima, a ne samo ispisati jedan primjerak crno-bijelo.
  • Dvije postavke rezolucije, tako da ovisno o dokumentu možete birati između oštrijeg teksta ili manje datoteke.
  • Sve se odvija u vašem pregledniku — vaš PDF nikada se nikamo ne prenosi.

Često postavljana pitanja

Trebam li ovo samo za crno-bijeli ispis?

Obično ne — većina pisača i dijaloga za ispis ima vlastite opcije „Crno-bijelo” ili „Sivi tonovi”, koje za jedan otisak daju oštriji rezultat jer stranicu nije potrebno prvo pretvoriti u sliku. Koristite ovaj alat kada vam je zaista potrebna datoteka u sivim tonovima — za slanje nekome, arhiviranje ili prijenos negdje gdje je potrebna već pretvorena datoteka.

Hoće li datoteka postati manja?

Ne nužno. Svaka stranica postaje spljoštena slika, pa dokument koji se izvorno uglavnom sastojao od malog, kompaktnog teksta može kao JPEG stranice u sivim tonovima postati veći, iako vizualno izgleda jednostavnije. PDF datoteke s puno slika u boji vjerojatno će postati manje.

Ostaje li tekst nakon toga moguće označiti ili pretraživati?

Ne — pretvorbom u sive tonove svaka se stranica spljošti u sliku, pa tekst više nije moguće označiti ni pretraživati — isti kompromis nastaje i kod VitePDF alata Kompresija PDF-a i Prikrij sadržaj PDF-a kada oni rasterizacijom obrađuju stranicu.

Postoji li ograničenje veličine datoteke?

Datoteke do 140 MB besplatne su — Premium verzija u potpunosti uklanja to ograničenje.
