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.
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.

FAQs
Frequently Asked Questions
Find answers to the most common questions about this tool.
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.
Yes — files up to 15MB. Above that, browser-based Base64 conversion gets slow and memory-heavy, so we cap it there. If your image is close to the limit, use the built-in Compress/Resize option before converting to shrink it first.
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.
Yes — copying the 'Data URI' or 'HTML' output format and pasting it directly into your email's HTML lets the image display inline without depending on an externally hosted file, which some email clients block by default.
Yes — just paste the link into the 'Have an image link?' box under Import from the Web, then click Fetch & Convert. The tool fetches and encodes it right in your browser. Note: some sites block this type of direct browser access (a security setting called CORS) — if that happens, just download the image and upload it the normal way instead.
Yes — use the Compress/Resize panel to set a max width/height and a quality level before encoding. This is useful because Base64 text is always roughly 33% larger than the original image file, so compressing first keeps your embedded code leaner.
