Motorola S-record ↔ Binary Converter
Validate S-record lengths, checksums and address widths, reconstruct binary or produce S1/S2/S3 data records.

Open files
Text input up to 200,000 characters; files up to 2 MiB; up to 10 files in a ZIP batch. Table converters allow 1,000 rows and 100 columns. For encoding, files are read as raw bytes. For decoding, open encoded text; GZIP decompression reads a compressed binary file.
Try the example, paste input or open a file to begin.
Supports S0 headers, S1/S2/S3 data, S5/S6 counts and S7/S8/S9 termination. Reconstructed span is at most 2 MiB; overlap and checksum errors are rejected. Binary loses address metadata, so retain the audit. Each input file must use a single data address width.

Questions & answers
What can Motorola S-record ↔ Binary Converter convert?
Validate S-record lengths, checksums and address widths, reconstruct binary or produce S1/S2/S3 data records.
Which format rules should I check?
Supports S0 headers, S1/S2/S3 data, S5/S6 counts and S7/S8/S9 termination. Reconstructed span is at most 2 MiB; overlap and checksum errors are rejected. Binary loses address metadata, so retain the audit. Each input file must use a single data address width.
Can I convert several files?
Yes. Open up to 10 files, select the settings and choose Convert files to ZIP. The status table identifies converted and failed files. The downloaded ZIP includes outputs and an audit; failures are not silently treated as successful.
How do I check the result?
Review the converted preview and audit before downloading. Check the stated format limitations, especially timing precision, omitted CSV columns and address metadata. Binary output downloads the actual bytes, not the hex preview.
What are the limits?
Text input up to 200,000 characters; files up to 2 MiB; up to 10 files in a ZIP batch. Table converters allow 1,000 rows and 100 columns.
Is input sent to a conversion service?
The conversion runs locally in a browser worker with bundled scripts. No conversion API is called. Copying and downloads happen only when you click their buttons. Saved comparisons stay in this tab and are cleared by reload. Ad-supported pages can load third-party scripts.
