Base64 Image Converter: what it does and how to use it
What this Base64 image tool does
This tool converts image files into Base64 data URLs and previews pasted Base64 image strings. Base64 images are useful when you need to embed a small icon, email asset, placeholder, or test image directly inside HTML, CSS, JSON, or a configuration file.
How it works
Choose an image file and the browser reads it with FileReader, producing a data:image URL. You can copy the complete data URL or just the raw Base64 portion. In the reverse direction, paste a data URL or raw Base64 string, choose the MIME type, and the preview renders locally.
Examples
- Convert a small SVG or PNG icon to a data URL.
- Preview a Base64 image returned by an API.
- Copy raw Base64 for JSON payload testing.
Security considerations
Images are not uploaded. Large Base64 images can make HTML and JSON heavy, so prefer normal image files for production assets unless embedding is required.
FAQ
Does SAVR upload the image?
No. The file is read locally by your browser and never sent to SAVR.
When should I use Base64 images?
Use them for small embedded assets, tests, emails, or previews. Avoid them for large production images.
Can I decode raw Base64?
Yes. Paste raw Base64 and select the expected image type to preview it.
