Document Compression

DjVu excels at compressing scanned pages — your HEIC document photos become remarkably compact without losing readability.

Efficient Storage

DjVu files are dramatically smaller than equivalent PDFs for scanned content — saving storage and speeding up transfers.

Cloud Processing

DjVu encoding runs on Convertio servers — no specialized document imaging software needed on your device.

About formats

HEIC (High Efficiency Image Container) is Apple's branded implementation of the HEIF (High Efficiency Image File Format) standard that uses HEVC (H.265) as its image compression codec. Apple adopted HEIC as the default photo format on iPhones and iPads starting with iOS 11 in September 2017, replacing JPEG for newly captured images. HEIC files store photographs compressed with the intra-frame coding mode of the HEVC video codec, which applies sophisticated prediction, transform, and entropy coding techniques that achieve roughly 50% better compression than JPEG at equivalent visual quality. The ISOBMFF (ISO Base Media File Format) container supports multiple images in a single file, enabling Live Photos (a still plus a short video clip), burst sequences, depth maps from dual-camera systems, and HDR gain maps that allow compatible displays to render extended dynamic range. HEIC also stores alpha channels, auxiliary images for computational photography features (portrait mode depth data, semantic segmentation masks), and comprehensive EXIF/XMP metadata. One advantage is storage efficiency: iPhones shooting HEIC use roughly half the storage of equivalent JPEG captures with no visible quality loss, a significant benefit on devices where storage is finite and photos accumulate rapidly. The format's integration with Apple's ecosystem is another key strength — HEIC files are natively supported across macOS, iOS, iPadOS, and iCloud Photos, and automatic JPEG transcoding during file sharing ensures compatibility when sending photos to non-Apple devices. HEIC can also be opened by Windows 10/11 (with codec), GIMP, ImageMagick, and Adobe Lightroom.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.

Frequently Asked Questions

Why convert HEIC to DJVU?

DjVu achieves extreme compression for document images — converting HEIC photos of documents or pages creates compact, shareable files.

What viewers open DJVU?

WinDjView, DjView, Okular on Linux, Sumatra PDF on Windows, and Evince on GNOME desktops handle DjVu documents.

Is DJVU good for photos?

DjVu excels at scanned documents, not general photography. Use it when your HEIC photos are of text pages, forms, or scanned materials.

Is DJVU smaller than PDF?

For scanned documents, DjVu often achieves significantly better compression than PDF — sometimes 5-10x smaller.

Is HEIC to DJVU conversion free?

Standard conversions are free. Premium plans support batch processing for document scanning workflows.
