Why Claude Crashes On HEIC (Unlike ChatGPT)
Claude is fundamentally different from ChatGPT when it comes to HEIC files. ChatGPT rejects the upload immediately with a clear "file not supported" error. Claude does something far more confusing: it accepts your HEIC file without any warning, then crashes internally while trying to process it.
Claude has a built-in "Convert HEIC to PNG" tool in its image processing pipeline. That internal converter silently fails. The result is a vague error message that gives you no clue your file format is the problem — you're left thinking Claude itself malfunctioned.
There is no mention of HEIC. No suggestion to convert. Claude's internal HEIC converter has been broken and unresolved. The only reliable fix is to convert to JPEG before uploading.
The Fix: Convert HEIC to JPEG Before Uploading
JPEG works perfectly in Claude. Its vision capability is excellent — the crash only happens because of the broken HEIC processing step. Remove that step by converting first, and Claude analyzes your photo without issue.
Use the Converter Above
- Drop your HEIC file into the converter at the top of this page.
- Download the converted JPEG.
- Upload the JPEG to Claude.ai.
Best for one-off conversions when you have a single photo to fix.
Install the Extension (Automatic)
- Install AI File Fixer from the Chrome Web Store.
- Upload any HEIC file to Claude.ai as normal.
- The extension silently converts it before it reaches Claude.
You never see the crash again — for every photo, every time.

Claude has a built-in image processing pipeline that fails silently on HEIC files. Unlike ChatGPT which rejects HEIC upfront, Claude accepts the upload and then crashes internally when trying to process it. The error message gives no indication the issue is your file format.
Not reliably. Claude's internal HEIC converter is broken and has been an unresolved issue. Converting to JPEG before uploading is the only reliable workaround until Anthropic fixes this.
Yes. Claude's vision is excellent with JPEG. The "response could not be generated" crash only happens because of the HEIC processing failure — the underlying vision capability is unaffected.
Yes. The AI File Fixer extension automatically converts HEIC to JPEG when you upload to Claude.ai, so you never see the crash again.
