Need help?Convert Image to HEIF Online
Turn JPG, PNG, HEIC, WebP, TIFF, BMP, or a camera RAW into HEIF — the High Efficiency Image File Format Apple ships as .heic. A HEIF still is an HEVC-intra-coded image that runs roughly half the size of an equivalent JPEG at similar quality, with support for 10-bit color, HDR, and transparency. The honest catch: HEIF is great for Apple-ecosystem storage but poorly supported elsewhere — Chrome, Firefox, and Edge can't open it, and Windows needs an extension installed first. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
How to Convert Image to HEIF
- Upload Your Image File: Drag and drop or click "+ Add Files" to add one or many images. The converter accepts 36 input types — JPG, JPEG, JFIF, PNG, GIF, HEIC, AVIF, WebP, BMP, TIFF, TIF, ICO, PSD, EPS, XCF, and RAW camera formats like CR2, CR3, NEF, ARW, DNG, RW2, ORF, PEF, RAF, 3FR, X3F, MRW, DCR, ERF, and MOS.
- Pick a Quality Preset: Open the options and set "Quality Preset" — it defaults to Very High (Recommended). Because HEIF is lossy, lower presets shrink the file further at the cost of detail; keep it high for an archive copy.
- Resize or Target a File Size (Optional): Use "Resolution Percentage" (Keep original by default), a Preset Resolution, or a custom Width and Height to downscale, or switch to "Specific file size" to hit an upload cap.
- Convert and Download: Click Convert and save the
.heiffile. No sign-up, no watermark.
HEIF vs JPEG, WebP, and AVIF
| Property | HEIF / HEIC | JPEG | WebP | AVIF |
|---|---|---|---|---|
| Standard | ISO/IEC 23008-12, MPEG-H Part 12 (2017) | ISO/IEC 10918 (1992) | Google (2010) | AOMedia (2019) |
| Codec | HEVC (H.265) intra | JPEG DCT | VP8 / VP8L | AV1 |
| Typical size at similar quality | ~40-50% smaller than JPEG | Baseline | 25-34% smaller than JPEG | ~50% smaller than JPEG |
| Color depth | Up to 10-bit and 12-bit | 8-bit | 8-bit | Up to 12-bit |
| Transparency / HDR | Yes / Yes | No / No | Alpha only | Yes / Yes |
| Native browser support | Safari 17+ only | Every browser | Chrome, Firefox, Edge, Safari 16+ | Chrome, Firefox, Safari 16.4+ |
| Best for | Apple-ecosystem storage savings | Universal sharing | Web delivery everywhere | Modern-browser delivery |
For an efficient image that actually opens on the open web, Image to WebP and Image to AVIF are far better supported than HEIF; for maximum compatibility on any device, Image to JPG is the safe pick.
Frequently Asked Questions
Why won't my HEIF file open on Windows, Android, or in Chrome?
HEIF support is narrow. On Apple devices it's built in from iOS 11 and macOS High Sierra 10.13 onward. On Windows you need the HEIF/HEVC Image Extensions installed from the Microsoft Store before Photos and File Explorer can open .heic/.heif files, and Android support varies by manufacturer. Among browsers, only Safari 17 and later can display HEIF natively — Chrome, Firefox, and Edge cannot open it at all. If the image needs to be viewable outside Apple's ecosystem, convert it back with HEIF to JPG or target Image to WebP instead.
Will converting to HEIF improve my image's quality?
No. HEIF is a more efficient, higher-bit-depth format, but it's lossy (HEVC-intra coding, like JPEG), so re-encoding a JPG to HEIF makes the file smaller, not sharper. The detail a JPEG discarded when it was first saved is gone for good, and HEIF can't bring it back. The real win here is storage — you get roughly the same picture in about half the bytes, plus a 10-bit container for future edits.
How much smaller will the HEIF file be than the original?
At similar visual quality, HEIF files are typically about 40-50% smaller than JPEG because the HEVC (H.265) codec compresses more efficiently than JPEG's older method. In our testing, a 12-megapixel JPEG re-encoded to HEIF at the Very High preset came out roughly half the original size with no visible difference on screen. Heavily detailed photos compress less than flat or smooth ones, so treat the 40-50% range as a guide rather than a guarantee.
What's the difference between HEIF and HEIC?
HEIF (High Efficiency Image File Format) is the container, standardized as ISO/IEC 23008-12, MPEG-H Part 12. HEIC is the specific case where that container holds an image coded with HEVC (H.265) — which is what Apple uses, and why iPhone photos carry the .heic extension. In everyday use the terms are interchangeable; the files this tool produces are HEVC-coded HEIF images.
What input formats can I convert to HEIF?
This is a general image-to-HEIF landing tool, so it accepts 36 input types: JPG/JPEG/JFIF, PNG, GIF, HEIC, AVIF, WebP, BMP, TIFF/TIF, ICO, PSD, EPS, XCF, and a wide set of RAW camera formats — CR2, CR3, CRW, NEF, ARW, DNG, RW2, ORF, PEF, RAF, 3FR, X3F, MRW, DCR, ERF, and MOS. Each source is decoded and re-encoded as a HEVC-coded HEIF image at the quality preset you choose.
How are my files handled, and are they private?
Your image is uploaded over an encrypted (TLS) connection, converted on our servers, and the files are deleted automatically a few hours after conversion. There's no sign-up, no watermark, and your files are never shared or made public. The practical limit on a very large RAW or PSD is upload size and time, not your device.
