About This Tool

The tool accepts a floppy image file and a target format, performing a non-destructive re-encapsulation that preserves the logical data layout. It supports common formats such as IMG, IMA, VHD, VDI, VMDK, and raw images, and can adapt geometry if needed to fit target capacities. The core workflow includes detection of tracks, heads, sectors per track, and bytes per sector, followed by a byte-for-byte transfer into the chosen output container. Optional padding or trimming allows alignment to standard capacities (e.g., 1.44MB) while maintaining data integrity. The converter emphasizes data preservation, enabling reliable mounting in emulators or virtualization platforms after conversion. It is valuable for archivists seeking long-term accessibility and for developers whobuild virtualization or emulation pipelines that require standardized image formats. Unique value lies in non-destructive re-encapsulation across multiple formats, explicit geometry handling, and optional integrity verification to detect any transformation discrepancies. Typical use cases include preparing a legacy game or OS disk for modern hypervisors, converting a historical archive fordisk image compatibility, or creating a portable image suitable for distribution to researchers. Core features cover input validation, geometry detection, format mapping, byte-for-byte copy, optional resizing, integrity checks, and detailed output metadata. The tool is platform-agnostic, designed for professional workflows in IT, archiving, and retro computing, while remaining accessible to hobbyists who manage emulated environments and archive collections.

How to Use

  1. Provide inputs: upload input_image and select target_format.
  2. Optional: override geometry (tracks, heads, sectors_per_track, bytes_per_sector) and enable padding or trimming.
  3. Set optional compression or integrity check as needed.
  4. Run conversion to produce output_image.
  5. Download output and verify against source if checksums were generated.

Frequently Asked Questions

Find Quick Answers

Which formats are supported for input and output?
Supported inputs include IMG, IMA, RAW, and packaged disk images. Outputs cover IMG/IMA, VHD, VDI, VMDK, and raw formats. The tool preserves the logical content while adapting to the target container's structure.
Can I preserve exact sector order and gaps?
Yes. The conversion operates at the logical level, copying sector data and gap structures without altering byte sequences. If geometry changes are required for the target format, padding or trimming is applied conservatively to maintain data integrity.
Is data integrity verified after conversion?
An optional integrity check computes a cryptographic hash (e.g., MD5 or SHA-256) of the input and output images to verify byte-for-byte equivalence where feasible. Failures are reported with diagnostic details.
What are the limitations?
The tool does not repair damaged or unreadable sectors, recover lost data, or reinterpret corrupted information. It focuses on non-destructive re-encapsulation to a chosen disk image format.
