HEIC Converter
Convert HEIC files to JPG, PNG, WebP, and 11 more formats — free, online, no upload
What Is HEICcon? A Free HEIC Image Converter
HEICcon is a free heic converter that transforms Apple's or Iphone's HEIC photos into 14 different formats – JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, PSD, ICO, and more directly in your browser.
The heic file converter decodes HEIC using WebAssembly compiled version of libheif v1.21.2 library. What it means is that HEICcon decodes HEIC images directly in the browser without needing to upload them to the server.
The encoding process varies by format: JPG, PNG, and WebP use the browser's Canvas API; specialized formats like PSD and TIFF use dedicated JavaScript libraries.
Most HEIC image converter tools like cloudconvert, freeconvert, heictojpg.com upload your files to remote servers for conversion. HEICcon runs and converts all your HEIC images entirely in your browser. Your private photos never leave your device.
You can convert a batch of up to 50 HEIC photos at once. All files are converted in parallel via Web Workers from your browser, which means they get converted very fast. Drag and drop, paste a URL, or import from Google Drive and Dropbox. Free, unlimited, no sign-up.
Supported Output Formats
HEICcon supports 14 output formats. Each has different strengths — pick based on where the image is going.
Format | Type | Transparency | Best For |
|---|---|---|---|
JPG | Lossy | No | Photos for web, email, social media |
Lossless | Yes | Screenshots, graphics, design assets | |
WebP | Lossy | Yes | Modern web images (smaller than JPG) |
Lossy | Yes | Best compression, newest browsers | |
GIF | Palette | Yes | Simple graphics, 256 colors max |
BMP | Uncompressed | No | Legacy software, Windows icons |
TIFF | Uncompressed | Yes | Print, publishing, archival |
PSD | Flattened | Yes | Opens in Photoshop, Affinity Photo |
ICO | Multi-size | Yes | Favicons, Windows application icons |
TGA | RLE | Yes | Game development, 3D rendering |
PPM | Raw | No | Academic, Unix pipelines |
The heif converter also accepts .heif files — HEIF is the container format, HEIC is the codec name. Both work identically.
For most users, JPG is the right choice. It opens everywhere and produces reasonable file sizes. Choose PNG if you need lossless quality or transparency. Choose AVIF for the smallest files on modern browsers.
How to Convert HEIC Files
Four steps. Nothing to install.
1. Pick a format. The dropdown defaults to JPG. Select any of the 14 output formats — PNG, WebP, AVIF, TIFF, and more.
2. Add files. Drag .heic or .heif files onto the drop zone. Or click to open a file picker. The chevron menu lets you paste a URL or import from Google Drive and Dropbox. The heic online converter accepts up to 50 files per batch.
3. Adjust settings. Compression toggle is off by default — output uses highest quality for your chosen format. Turn it on for a quality slider. To resize, enter width and height (1–16,384 px). Three fit modes: contain, cover, stretch.
4. Convert and download. Click Convert or press ⌘Enter (Mac) / Ctrl+Enter (Windows). Each file processes through a Web Worker — HEIC decode is heaviest at ~40% of the progress bar. When done, download files individually or as a ZIP.
The heic photo converter handles everything from a single iPhone photo to a batch of 50 vacation shots.
What Is a HEIC Image File Format?
A heic file is a photo saved in Apple's High Efficiency Image Container format. Since iOS 11, iPhones save photos in HEIC format by default.
HEIC uses the HEVC video codec for compression and due to this, the files are roughly 50% smaller than JPEG at the same visual quality. HEIC also supports 10-bit color depth, Display P3 wide gamut, transparency, and Live Photo embedding.
The problem with HEIC format is compatibility. Windows doesn't open heic file formats without a paid codec extension. Most web browsers can't display HEIC (Safari is the exception). Email clients, social platforms, and older image editors reject the format entirely.
Converting solves this. The heic converter online transforms HEIC into universally compatible formats — JPG opens everywhere, PNG preserves lossless quality, WebP works on all modern browsers. The conversion runs in your browser, so there's nothing to install and no files to upload.
If you have iPhone photos that won't open on your Windows PC or won't upload to a website, HEIC compatibility is almost certainly the issue. Converting to JPG is the fastest fix.
Frequently Asked Questions
Yes. HEICcon is a free heic converter with no daily limits, no sign-up, and no watermarks. Convert as many files as you want. Batch up to 50 at once. The conversion runs in your browser — there's no server cost to pass on to users.
Select JPG from the format dropdown (it's the default). Drag your .heic files onto the drop zone. Click Convert. Download the resulting .jpg files individually or as a ZIP. The entire process takes seconds and requires no software installation.
If you just want to view the photo: convert it to JPG or PNG first, then open the result. HEICcon generates a preview thumbnail during conversion, so you can see what's in the file before downloading. On Windows, you can also install Microsoft's HEVC extension from the Store — but it's a paid download. Converting to JPG is faster and free.
HEICcon runs entirely in your browser. No server processes your images. No upload endpoint exists — your files never leave your device. The only network requests are loading the page and (for cloud imports) fetching files from Google Drive or Dropbox. The conversion itself is 100% local.
HEIF is the container format (High Efficiency Image Format). HEIC is HEIF with HEVC compression — the specific codec iPhones use. Both .heic and .heif files work identically in HEICcon. The decoder handles both extensions.
