Pretvorite HEIC u PDF

What HEIC u PDF does

HEIC u PDF puts images into a PDF, one image per page. It is the usual way to send several photos, scans or screenshots as a single document, for example receipts for an expense claim or photographed pages of a paper form.

JPG files are normally embedded as they are, without re-encoding. Other formats are decoded in the browser and stored as JPEG at the quality you choose, or as PNG when the image has transparent areas. Images are placed in the order of the file list, and each one is scaled to fit and centered on its page.

Settings explained

Page size

Same as image, the default, makes each page as large as its image plus the margin, at 96 pixels per inch. Choose A4, Letter, A3, A5 or Legal when the PDF will be printed or needs a standard size.

Orientation

Only shown when a fixed page size is selected. Automatic uses landscape pages for images that are wider than tall and portrait pages for the rest. Portrait or Landscape uses the same orientation for every page.

Margin

White space around each image, from 0 to 72 points, where 72 points is one inch (25.4 mm). The default is 0. A margin of 18 to 36 points looks good on printed pages.

Quality

JPEG quality from 30 to 100 percent, default 92, for images that have to be re-encoded, such as PNG, HEIC or WEBP. JPG files embedded unchanged and images with transparency, which are stored as PNG, are not affected.

What changes when you convert HEIC to PDF

HEIC is the default photo format on iPhone and iPad. Converting to PDF makes the photo open on Windows, Android and every website.

Each image becomes one PDF page. JPG photos are embedded as they are, without re-compression. Other formats are converted to high-quality JPG, or PNG when they have transparency, before they are placed on the page.

Format comparison

Što je HEIC?

HEIC (High Efficiency Image File Format (HEIF)) je format za slike predstavljen 2015. godine (razvio: MPEG). Format koristi kompresiju s gubicima i podržava prozirnost. Datoteke imaju nastavak .heic ili .heif.

HEIC is an image stored in the HEIF container and compressed with the HEVC (H.265) video codec. Apple made it the default photo format on iPhones starting with iOS 11. One file can hold several images, depth maps and other data, and it keeps quality similar to JPG at a noticeably smaller size.

HEIC is good for storing many photos on a phone, because it saves space while keeping good quality. It can also keep extra information in the same file, such as the depth data used for portrait effects.

Most websites and many Windows and Android apps cannot open HEIC files directly. The HEVC codec is covered by patents, which limits free support. When you share photos outside Apple devices, converting to JPG is often necessary.

HEIC opens natively on iPhone, iPad and Mac. Recent Windows versions can open it with the HEIF and HEVC extensions from the Microsoft Store, and many recent Android phones can read it. Most browsers other than Safari cannot display it.

Što je PDF?

PDF (Portable Document Format) je format za dokumente predstavljen 1993. godine (razvio: Adobe). Datoteke imaju nastavak .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

• Use the up and down arrows next to each file to set the page order before you create the PDF. The first file in the list becomes page 1.
• With Same as image, a photo 4000 pixels wide gives a page more than one meter wide. Choose A4 or Letter for documents that will be printed.
• JPG files are embedded without reading the rotation tag that some phones and cameras store. If a photo appears sideways in the PDF, turn that page with Rotate PDF.
• With one image, the PDF is named after that image. With several images, the result is called images.pdf, so rename it before you send it.

How HEIC u PDF works in your browser

The PDF is opened with pdf-lib, an open-source PDF library that runs in your browser. Pages are copied, rotated, resized or cropped at the PDF object level, so text stays text and vector graphics stay sharp.

Because the original page content is copied rather than re-rendered, there is no quality loss. The only exception is an option that explicitly turns pages into images. The new PDF is assembled in memory on your device and offered as a download.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. HEIC u 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.
