How to Use

Step 1

Upload Your Image

Select a PNG, JPG, WEBP, SVG, or GIF file from your device to get the conversion started right away.

Pick the format you need — a raw Base64 string, a Data URI, an HTML image tag, CSS source code, Markdown, or JSON — depending on where the code is headed.

Step 3

Copy the Generated Code

Click the one-touch copy button to grab your generated code, and compare the original file size against the new Base64 string size before deciding whether to embed it.

Step 4

Decode a String Back to an Image

Paste a Base64 string into the built-in decoder any time you need to convert it back into a viewable, downloadable image file.

Key Features

Fast & Secure Conversion

All conversions happen locally in your browser. Your images are never uploaded to any external servers, keeping your data 100% private

Multiple Output Snips

Get instant code formatted as a raw string, a Data URI, or pre-made HTML/CSS tags for direct copy-pasting into your development projects.

Real-Time File Details

Compare the original file size with the generated Base64 string size, and preview your image structure live on the dashboard.

Two-Way Utility

Not just an encoder! Easily switch to the Base64 to image tool option to decode any string back into its original image format.

Frequently Asked Questions

It's a free online tool that encodes binary image data — like a PNG, JPG, or SVG file — into a text-based Base64 string that can be embedded directly inside code instead of linked as a separate external file.

It supports all major image formats, including PNG, JPG, JPEG, WEBP, SVG, and GIF, converting any of them into a Base64 string or one of several other developer-friendly output formats you might need.

Embedding a Base64 string directly into your HTML or CSS reduces the number of separate HTTP requests your page has to make to load images, which can help for small icons, inline graphics, or email templates that can't reliably load external image files at all.

There's no hard limit, but images under about 10 MB are recommended to keep the conversion running quickly and smoothly right inside your browser tab.

Yes — paste your encoded text string into the built-in decoder and it converts it back into a viewable, downloadable image file, so you don't need a separate tool for the reverse direction.

Yes — the entire conversion runs locally in your browser, so your images and the generated code are never uploaded to or processed on our servers, even for unreleased branding assets or private icons.

No quality loss occurs at any stage. Base64 encoding is a lossless text representation of your image's exact binary data, so nothing is compressed or altered. When you decode a Base64 string back into an image using our built-in two-way tool, you get back the exact original file, pixel for pixel, with full quality retained.
