Image Hex Editor

The tool exposes the raw binary content of image files and displays a dense hex grid synchronized with byte offsets and common markers. It supports safe viewing and modification of selected bytes, while preserving the ability to revert changes if needed. This is particularly useful for diagnosing header corruption, validating format signatures, and understanding how pixel data is stored in different formats.\n\nConceptually, a file is read into memory, a hex dump is produced, and a grid maps each byte to a cell. Edits are applied to a temporary working copy with delta tracking, and a validation pass checks header integrity, length fields, and critical markers. The tool also estimates how changes affect file size and structure.\n\nDevelopers, QA engineers, and forensic analysts benefit from precise, non-destructive analysis and fast iteration. Unique value lies in in-browser, non-invasive edits, delta export for review, and presets tailored to common formats (PNG, JPEG). Use cases include header patching, CRC checks, and quick byte-level sanity checks without a full image editor.
