See the Spec & MIME section for authoritative sources (retrieved 2026-08-29).
Official spec & structure

| MIME type | image/jpeg |
| IANA registration | Registered — image/jpeg |
| Structure | JPEG is a lossy compressed raster format built from markers (SOI/EOI) and Huffman/DCT-coded scans. Defined by ITU-T T.81 / ISO/IEC 10918. |

Common corruption & repair
When JPEG Image typically corrupts
Corrupted header (SOI missing)
Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.
Pink/green artifact blocks
Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.
Truncated download
Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.
Step-by-step recovery path
- Identify the exact symptom. Note what happens when you open the file — won’t open, partial content, garbled characters, or a wrong-extension mismatch. The symptom drives the next step.
- Make a read-only backup first. Copy the original file to a safe location before any fix attempt, so you can retry if an approach makes things worse.
- Try the source app’s open/repair. Reopen the file in the program that created it (or a compatible one) and use its Open-and-Repair or Save-As option, which often rebuilds a damaged header.
- Apply the format-specific recovery steps. Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.
- Use a conversion path as a fallback. If repair fails, convert the format using the in-browser converters linked in the Tools section, then re-open the result.
When recovery is not possible
No software can recover a file that has been overwritten or truncated to zero bytes, a container whose core structure is physically destroyed, or a file that is DRM- or password-encrypted without the key (for example DRM-locked WMA or M4V). In those cases, stop writing to the storage medium, restore from a backup or version history, and — for the only copy of something critical — consider a professional data-recovery service. The steps above are general troubleshooting, not a guarantee of recovery.
Recovery decision tool
Always work on a copy. Steps are ordered from safest to deepest.
My recovery plan — JPEG Image (.jpg)
- 1. Stop using the file. Make a working copy — never repair the original.
- 2. Start with the app's built-in repair (Open and Repair / recover), then try a second app, then a dedicated recovery tool.
- 3. Follow the recovery path for JPEG Image: Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.
- 4. Verify the repaired copy opens and the content is complete before deleting anything.
Format-specific guidance: Re-download; remove bad EXIF; re-encode via the site's image converter; some apps auto-skip corrupt blocks.

How this format page is built (spec, repair & links)
Each format page lists the failure modes and recovery steps stored in the FileFixPro format dataset for that extension, plus an official-spec section that links to IANA or the format's standards body/vendor (retrieved 2026-08-29). The interactive recovery decision tool combines your selected symptom and file importance into a graded plan and runs entirely in your browser. Per-format version lineage and unverified spec URLs are intentionally omitted to avoid presenting invented facts — items we have not independently confirmed are marked verify-locally.
