Перегляд PDF онлайн

What Перегляд PDF does

Перегляд PDF opens a PDF in a simple viewer in your browser. It is useful on shared or work computers without a PDF app, or when a file does not open in the viewer you normally use. You can zoom, jump to a page and search the text.

Pages are rendered with pdf.js as you scroll, so long documents open quickly and only the pages near the screen are drawn. Password-protected files ask for the password before they open. The reader only displays the file: it does not change it or create a new one.

Як користуватися: Перегляд PDF

1. Перетягніть PDF або натисніть, щоб відкрити файл.
2. Прокручуйте, масштабуйте, переходьте до потрібної сторінки або шукайте в тексті.

When to use Перегляд PDF

• Read a PDF attachment on a library, school or office computer where you cannot install software.
• Look through a long manual or report and jump straight to the pages that mention a product name or keyword.
• Open a password-protected bank statement or payslip on a device without a PDF app by entering its password.
• Check a PDF you just created with another tool, such as a merged or compressed file, before you send it.

Settings explained

Zoom in

The plus and minus buttons change the zoom in steps of about 20 percent, from 25 to 400 percent. When a file opens, the zoom is set so the page fits the width of the viewer.

Page

The page box shows the page you are viewing and the total number of pages. Type a page number and press Enter to jump straight to that page.

Search in document

Type a word or phrase and click Find. The search ignores upper and lower case and lists every page with a match as a button. The viewer jumps to the first one; click the others to go there.

Password

Appears when a file is protected. Enter the password and click Open. If it is wrong, a message appears and you can try again. The file itself stays protected.

Що таке PDF?

PDF (Portable Document Format) — формат документів, представлений у 1993 році (розробник — Adobe). Розширення файлів: .pdf.

PDF was created by Adobe to show documents the same way on any device and printer. A PDF file describes pages with text, fonts, vector graphics and images at fixed positions. It became an open ISO standard in 2008, and there are special variants such as PDF/A for archiving and PDF/X for printing.

PDF is the right choice for documents that must look the same everywhere, such as contracts, invoices, forms, manuals, reports and files for printing. It also supports digital signatures, fillable forms, comments and password protection.

PDF is hard to edit, because text is stored as positioned pieces, not as flowing paragraphs. Converting a PDF to Word may change the layout. Scanned PDFs contain pictures of text, not real text, unless OCR has been applied.

All major web browsers open PDF files directly. Windows, macOS, iOS and most Android phones include a PDF viewer, and Adobe Acrobat Reader and many free apps can view, annotate and fill PDF forms on all platforms.

Tips for the best result

• Search finds words only in PDFs that contain real text. Scanned pages are images, so a search there finds nothing, even if you can read the words.
• The search shows which pages match but does not mark the words on the page. Zoom in to find the word quickly on a page with a lot of text.
• In long documents, use the page box instead of scrolling. Pages are drawn only when you reach them, so after a fast scroll a page can stay blank briefly.
• Use Start over to close the file and open another one. The reader never changes your file, so there is nothing to save.

How Перегляд PDF works in your browser

Pages are rendered with pdf.js, the PDF engine built into Firefox, running on your device. It reads fonts, vector graphics and embedded images and draws each page on a canvas.

For conversions and previews, the rendered pages are encoded as images in your browser. Text search, zoom and page navigation all work on the local copy of the file.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Перегляд PDF works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
