How do I convert a byte array into an image?

Paste decimal or hexadecimal byte values into the converter and select Convert to Image. The browser rebuilds the binary file, detects its format, and displays a downloadable preview.

Can I paste Uint8Array or Node.js Buffer output?

Yes. The converter supports Uint8Array values, Node.js Buffer output, Buffer.from arrays, decimal and hexadecimal byte sequences, Base64, data URLs and raw SVG.

Is Base64 the same as image bytes?

No. Image bytes are binary data, while Base64 is a text representation of those bytes. Both can reconstruct the same image, but Base64 is usually about one third larger.

Are my bytes uploaded to a server?

No. Parsing, decoding, signature detection and preview generation run locally in the browser.

What is the maximum supported size?

The decoded image is limited to 10 MB and pasted text is limited to 10 million characters. Available browser memory may impose additional practical limits.

Bytes to Image Converter

Convert byte arrays, Uint8Array output, Node.js Buffer data, hex bytes,
Base64 strings, and image data URLs into visible image previews.

Detects JPG, PNG, GIF, BMP, TIFF, SVG, WEBP, AVIF, and ICO images. Preview support depends on your browser.

Your bytes are processed locally in the browser and never leave your device.
