PNG to Base64
Base64 ToolsNew
Encode PNG images into Base64 with full transparency preserved.
Examples: PNG images saved from Figma, exports from Photoshop, or assets downloaded from your CMS.
Encode a PNG file into Base64, ready to paste into HTML, CSS, JSON, or a data URL. Lossless transparency makes PNGs ideal for icons and logos.
Embedding tiny logos and icons inside HTML emails, CSS sprite alternatives, or design tokens.
For pure-text payloads use the Text to Base64 tool.
Does the file leave my browser?
No. Encoding runs in your tab — nothing is uploaded.
Is there a file size limit?
Practical limits depend on browser memory; encoding is comfortable up to ~50 MB.
Is the alpha channel preserved?
Yes — PNG bytes are encoded faithfully, including transparency.
