How to use Convert PNG to Hex
- 1. Upload your PNG. Add the file you want to inspect, such as icon.png. The tool reads its raw bytes directly rather than decoding the image into pixels.
- 2. Choose spacing and case. Turn on Space between bytes to insert a space after each hex pair for readability, and Uppercase digits to render letters as A through F instead of lowercase.
- 3. Copy the hex dump. Copy the resulting hex text, which starts with the PNG signature bytes like 89 50 4e 47, and paste it into a hex editor, forensic report or debugging note.
When to use Convert PNG to Hex
Convert PNG to Hex dumps the raw bytes of a PNG file as readable hexadecimal text, which is the level below pixels where file format debugging and signature verification actually happen. Convert PNG to Hex is for anyone who needs to see the exact bytes on disk rather than the decoded image.
- Verifying a file signature. A developer investigating why an upload validator rejects a file dumps icon.png to hex to confirm the first bytes match PNG's standard 89 50 4e 47 signature.
- Debugging a corrupted image file. A support engineer troubleshooting a broken image attachment inspects the raw hex bytes to spot truncation or a mismatched chunk length header.
- Writing a binary file format tutorial. A technical writer explaining how PNG chunks work dumps a small sample file to hex to show readers the exact byte layout of the header and IDAT chunk.

About the Convert PNG to Hex tool
Convert PNG to Hex runs as plain JavaScript in your browser tab, with no server behind it. Dump the raw bytes of a PNG file as hexadecimal text. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's PNG Tools section, 108 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Space between bytes and Uppercase digits, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
