Frequently Asked Questions about HEIF to PDF Conversion

Find quick, clear answers to common questions about converting HEIF to PDF. Below, we cover how the process works, supported devices and browsers, file limits, privacy and security, and tips for best results—so you can convert with confidence.

What is the difference between HEIF and PDF

HEIF (High Efficiency Image File Format) is an image and photo container that stores high-quality pictures and bursts with efficient compression, often using HEVC/H.265. It supports features like transparency, depth, live photos, and multiple images in one file, making it ideal for modern photography on mobile devices. In contrast, PDF (Portable Document Format) is a document format designed to preserve layout across platforms, combining text, vector graphics, images, forms, and annotations for reliable viewing and printing.

Use HEIF when you need compact, high-quality images or image sequences; use PDF when you want to share or archive complete documents with fixed formatting. While a PDF can contain images (including ones converted from HEIF), it’s not optimized for photo editing or camera workflows, whereas HEIF is not intended for multi-page documents or rich text layouts.

Will the conversion affect image quality or metadata

In most cases, converting images preserves visible quality, but it can change it depending on the target format and settings. Lossy formats like JPEG may introduce compression artifacts, while lossless formats like PNG or TIFF keep original quality. Higher quality/bitrate settings reduce degradation but increase file size.

Metadata (EXIF, IPTC, XMP) may not always transfer automatically. Some conversions preserve camera data, GPS, and timestamps, while others strip them for privacy or compatibility. If keeping metadata matters, choose formats and options that explicitly enable metadata preservation and verify the output.

Are my HEIF files secure and deleted after conversion

We take your privacy seriously. Your HEIF files are transferred over encrypted connections (HTTPS), and we do not share or sell any content. Only the conversion process accesses your files to generate the output format you requested.

After conversion, your original HEIF and the converted files are automatically deleted from our servers. We also implement routine cleanup to remove any temporary data associated with the process.

For best security, avoid uploading sensitive content and delete results immediately after download if the option is available. If you need stricter control, consider converting files locally using trusted offline tools.

What is the maximum file size or number of files I can upload

The current limits are: a maximum file size of 100 MB per upload and up to 20 files per batch. If you exceed either limit, the upload will be blocked; try reducing the file size or splitting your uploads.

For best results, keep individual files under 100 MB and group no more than 20 files at a time. If you need to process more, upload in multiple batches.

Can I convert multiple HEIF images into a single PDF

Yes—most converters let you merge multiple HEIF images into a single PDF: upload your files, arrange the page order, choose page size and margins, then export as PDF. If needed, first batch-convert HEIF to JPEG/PNG and combine them into a PDF using a merge tool. On macOS, you can select images in Preview and choose “Print” > “Save as PDF”; on Windows, open images and use Print to PDF. For best results, ensure all images share the same orientation and adjust scaling to avoid cropping.

Will the resulting PDF be searchable or just an image

It depends on how the PDF is created. If the tool embeds selectable text, the PDF will be searchable, meaning you can copy text and use the PDF’s search function. If the PDF is generated as a flat raster layer, it will be just an image inside a PDF and not searchable.

Some converters offer OCR (Optical Character Recognition) to detect text in images and make the PDF searchable. Without OCR, any text that originated as pixels (not vector text) will remain non-searchable.

To ensure a searchable PDF, choose options like “retain text,” “embed fonts,” or “enable OCR” when available. If those aren’t present, the result is likely an image-only PDF.

How can I reduce the PDF file size while keeping good quality

Start by optimizing images: downscale oversized images to the document’s target display size and convert them to efficient formats with moderate JPEG quality (around 70–85%) or use JPEG2000/JBIG2 where appropriate. Remove unnecessary elements like hidden layers, embedded thumbnails, and unused fonts, and subset or embed only used glyphs to shrink font data. If possible, flatten complex transparencies and forms.

Use a PDF optimizer or print-to-PDF workflow: in Adobe Acrobat, choose Save as Other → Reduced Size PDF or PDF Optimizer to control image downsampling, compression, and object cleanup. In macOS, print and select Quartz Filter → Reduce File Size. With command line, Ghostscript can compress via presets (e.g., -dPDFSETTINGS=/screen or /ebook) and custom image sampling/compression flags.

Balance size vs. quality by testing multiple presets and reviewing key pages that contain fine text or graphics. Keep vector content as vector when possible (avoid rasterizing pages), and avoid over-compressing small text or line art. Finally, remove metadata, annotations, and embedded media you don’t need, and consider splitting very large PDFs into logical sections to simplify sharing.

Does the converter preserve orientation transparency and color profiles

Yes. Our converter preserves orientation (including EXIF rotation), transparency (alpha channels), and embedded color profiles whenever the target format supports them. For example, PNG and WebP keep transparency, while JPEG does not; supported ICC profiles are carried over or mapped to sRGB when required.

If a chosen format lacks a feature, we apply sensible fallbacks: orientation is baked into pixels, transparency is flattened against a neutral background, and profiles are converted to sRGB to maintain consistent appearance. You can maximize fidelity by selecting a format that supports the features you need.
