Local JPEG thumbnail extractor
Extract the JPEG thumbnail stored inside EXIF
Read the original JPEG bytes referenced by TIFF IFD1, view their encoded dimensions and download them. A thumbnail can be older or show different content from the main photo. This tool never creates a small replacement from the main image.
Samples are project-authored: the main image is a 240 × 160 corner chart; the separately encoded thumbnail is a purple 48 × 32 image labeled THUMB. Non-JPEG TIFF thumbnails are outside this release. Files are not uploaded.
Supported files and output
JPEG EXIF IFD1, up to 20 MiB input. Extracts the actual embedded JPEG byte range, capped at 512 KiB and bounded preview dimensions. No thumbnail and an unreadable offset have distinct results. The extracted image can differ from the current main photograph; no resized substitute is generated.
Read the result with its coverage
Stored fields can be edited, copied or removed. A successful read describes the selected file’s supported containers; missing fields cannot be recovered from its pixels. A damaged or unsupported container has its own result. Review private values before copying or sharing a report.
These file operations run locally. The separate image checker can send file-header data and a reduced image copy for a model reading. Read the method and limitations when that is the task you need.
