Image Format Converter Convert HEIC／WEBP／PNG／JPG in Your Browser, No Upload
💡 This tool can convert HEIC files OUT to JPG／PNG／WEBP, but since HEIC is a patent-licensed format with no open-source browser encoder, converting other formats INTO HEIC is not supported. Please keep this limitation in mind.

What is HEIC, and why won't my iPhone photos open?
HEIC (High Efficiency Image Container) is the image container Apple made the default camera format starting with iOS 11. Built on HEVC compression, it typically shrinks file size by 40–50% compared to JPG at the same visual quality, saving substantial storage space on your iPhone.
That efficiency comes with a real compatibility cost: when you send an iPhone photo to a Windows PC, an Android phone, an older browser, or upload it to a website, social platform, or company system that hasn't added HEIC support, the file often refuses to open, shows a blank thumbnail, or triggers an “unsupported file format” error. It's one of the most common everyday headaches for iPhone users worldwide, regardless of language or region.
🔒 This tool decodes and converts your image 100% locally in your browser. Nothing is ever uploaded to a server, and everything is cleared automatically once you close the page — your private photos stay private.
How to Use (3 Steps)
- Upload an image: drag and drop, or click to select a HEIC, PNG, JPG, or WEBP file.
- Automatic decoding: if a HEIC file is detected, it's decoded locally and previewed within a few seconds, depending on file size.
- Pick a format and download: choose your target format (JPG／PNG／WEBP). For JPG or WEBP, drag the quality slider to balance size and clarity, compare the before/after file size, then download with one click.

Frequently Asked Questions (FAQ)
Q1: Why won't photos from my iPhone open on Windows or other phones?
Since iOS 11, iPhones save photos in HEIC by default, but many older operating systems, browsers, and websites still lack native HEIC decoding support, causing files to fail to open or render incorrectly. Converting to JPG or PNG with this tool makes the image openable on virtually any device or platform.
Q2: Does this tool upload my photos to a server?
No. This tool uses browser-based WASM technology to decode and convert entirely on your own device — your photo never leaves your computer or phone.
Q3: Can I convert a PNG or JPG back into HEIC?
Not currently. HEIC is a patent-licensed format, and no mainstream browser ships an open-source HEIC encoder. Rather than fake a feature that doesn't really exist, this tool honestly supports only the “convert out of HEIC” direction and does not offer “convert into HEIC.”
Q4: Will the converted image lose quality?
Converting to PNG is lossless, so no quality is lost — but the file is usually larger. Converting to JPG or WEBP uses lossy compression, so you can use the quality slider to balance file size against clarity: a higher value means better quality but a larger file.
Q5: Where can I learn more about the HEIC format?
HEIC's formal name is the High Efficiency Image File Format (HEIF). You can find the technical details on Wikipedia: HEIF.
