XCF to HEIC

How to Convert XCF to HEIC Online

1. Upload Your XCF File: Drag and drop or click "Add Files" to select GIMP project files (.xcf). Flatten layered projects in GIMP first (Image → Flatten Image, then re-save the .xcf) — a multi-layer XCF is read as a multi-page image and a single layer is written, not the merged canvas. Batch conversion is supported — drop in an entire folder of XCFs to process them with the same settings.
2. Pick a Quality Preset: Default is "Very High (Recommended)". Pick Highest for archival-grade output, Medium or Low for smaller files, or switch to "Image Quality (%)" for a numeric slider. To meet a target size (Discord 10 MB, Gmail 25 MB, iMessage attachments), use "Specific file size" or "Target file size (%)" to auto-scale quality.
3. Resize if Needed (Optional): Under "Image Resolution," keep original, pick a Preset Resolution (4K, 1440p, 1080p, 720p), enter a custom Width × Height (aspect ratio is preserved when only one is set), or scale by Resolution Percentage.
4. Convert and Download: Click Convert. The rendered image is encoded with HEVC and wrapped in an HEIC container. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert XCF to HEIC?

XCF is GIMP's native project format — it preserves layers, channels, paths, selections, transparency, and guides, but only GIMP, Krita, Photopea, and a handful of other editors can open it. HEIC (High Efficiency Image Container, ISO/IEC 23008-12) is Apple's image format — the default photo format on every iPhone with an A10 Fusion chip or newer (iPhone 7 and later) since iOS 11 shipped on September 19, 2017. HEIC stores roughly twice as much image data as a same-quality JPEG by using HEVC compression, so a 1.18 MB JPEG drops to about 756 KB as HEIC at the same visible quality.

• Send GIMP edits to an iPhone or iPad — AirDrop, iMessage, and Apple Photos handle.heic natively. Exporting your XCF as HEIC means it lands on the device without re-encoding and without ballooning storage.
• Build assets for iOS / Mac apps — Xcode, SwiftUI, and AppKit all read HEIC. A flattened HEIC export from GIMP slots into asset catalogs at half the size of equivalent PNG or JPEG.
• Archive edited photos at half the JPEG size — HEIC's HEVC compression means a folder of finished photo edits takes about 50% less disk space than the same images saved as high-quality JPEG, with no visible quality loss.
• Match the format your camera roll already uses — if you sync GIMP edits back into Apple Photos, keeping HEIC avoids the JPEG transcode step that Photos otherwise performs.
• Keep wide-gamut and 10-bit data alive — HEIC supports 10-bit and 12-bit color, where JPEG caps at 8-bit. If your XCF was created from a high-bit-depth RAW import, HEIC preserves more tonal range than a JPEG export.
• Skip GIMP's libheif dependency — on some Linux installs the bundled GIMP can't export HEIC unless libheif is installed separately. Converting online avoids the package-management detour.

Frequently Asked Questions

Are my GIMP layers preserved in the HEIC?

No, and the merge is not performed here either. HEIC is a delivery format, not an editing format, and a multi-layer XCF is read as a multi-page image from which a single layer is written rather than the composite GIMP shows on canvas — so the other layers' artwork is missing and the regions they covered arrive transparent. Flatten in GIMP before uploading (Image → Flatten Image, then re-save the .xcf) and the HEIC matches your canvas exactly; a single-layer XCF is already fine. Keep the original .xcf as your editable source of truth, and if you need a layered file other apps can edit, export PSD or layered TIFF from GIMP directly — that is a GIMP export, not a conversion this page performs.

Will the HEIC open on my iPhone?

Yes — every iPhone with iOS 11 or newer (iPhone 5s and later run iOS 11; iPhone 7 with the A10 Fusion chip and later can both display and capture HEIC). AirDrop the file or save it to iCloud Drive and the Photos app opens it natively, no plugin required.

Will my HEIC open on Windows?

On Windows 10 version 1803 and later, install the free "HEIF Image Extensions" from the Microsoft Store and HEIC opens in Photos and File Explorer. Windows 11 22H2 and later ship HEIF support built-in. If a colleague on older Windows can't open the file, send them a HEIC to JPG link instead.

What happens to transparency in my XCF?

HEIC supports an alpha channel, so transparent areas in the XCF are preserved in the HEIC. If the result looks far more transparent than expected, the cause is an unflattened stack rather than the encoder — the areas the missing layers covered are simply empty. Flatten in GIMP and re-convert. If you need maximum transparency compatibility (some older HEIC viewers ignore alpha), convert to XCF to PNG instead — PNG transparency works everywhere.

Why is my HEIC so much smaller than the XCF source?

Two reasons. First, XCF stores every layer, channel, and path uncompressed-ish (RLE or zlib) — a five-layer 4000×3000 XCF can hit 80-200 MB. HEIC stores a single rendered image. Second, HEVC is far more aggressive than the lossless schemes in XCF: at "Very High" quality the visible image is virtually identical, but the file is roughly half the size of a JPEG export and a fraction of the original XCF.

Can I export 10-bit or 12-bit HEIC?

HEIC itself supports up to 12-bit per channel and the converter writes 8-bit by default for maximum compatibility. If your downstream tool (Photoshop, iOS Photos) expects 8-bit, leave it. Note that Photoshop currently reads only 8-bit HEIC, so 10- and 12-bit files are best opened in Apple Preview, GIMP 2.10.22+, or Affinity Photo.

Should I use lossless HEIC?

Only if file size doesn't matter and you're archiving the master. Lossless HEIC is roughly 4-8× larger than the default lossy preset and is rarely necessary — at "Very High" quality (~90%) virtually no one can spot artifacts. For true archival, keep your.xcf and export an additional lossless XCF to TIFF instead — TIFF has decades-deep tooling support.

Can I batch convert a folder of XCFs at once?

Yes. Upload as many XCF files as you want, apply the same Quality Preset and Resolution settings to all of them, or override per-file. Each file converts in parallel on our servers and downloads individually or as a ZIP archive.

Why not just use HEIF instead of HEIC?

They're nearly the same thing. HEIF is the umbrella ISO/IEC 23008-12 container; HEIC is HEIF specifically encoded with HEVC, which is what Apple uses and what the.heic extension implies. If a downstream tool wants the more generic extension, use XCF to HEIF — the bytes are functionally identical for HEVC content.
