Image to Base64
Encode PNG, JPG, and WebP images as Base64 data URIs directly in your browser.
Convert a PNG, JPG, or WebP file into a Base64 data URI without uploading it.
Accepted: PNG, JPEG, WEBP · Max 10 MB · Max 25 MPThe encoded data URI appears here after the browser reads the file. Base64 is encoding, not encryption.
Image encoding workflow tips
Base64 image strings are useful for small prototypes, examples, and temporary developer handoffs, but they can become much larger than the original binary file.
Keep it for small assets
Use Base64 for icons, tiny screenshots, test fixtures, or documentation samples. For production pages, normal image files are often easier to cache and maintain.
Optimize before encoding
Try Image Resizer, Image Compressor, or PNG to WebP before encoding if the source image is larger than needed.
Decode and inspect related data
Use Base64 to Image to verify a data URI round trip. For text payloads, use Base64 Encoder/Decoder. For structured snippets around the image, use JSON Formatter or the Developer Data Toolkit.
What this tool does
Image to Base64 reads a local image file with browser APIs and returns a copyable data URI for small test fixtures, documentation examples, email snippets, and CSS or HTML prototypes without uploading the image.
Common use cases
Encode a small local image as a Base64 data URI for developer prototypes, documentation, fixtures, or copyable examples.
Use Image to Base64 when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Choose or drag a PNG, JPG, or WebP file into the upload area.
- Review the preview, input type, file size, dimensions, and encoded output length.
- Copy the Base64 data URI or download it as a .txt file for your local workflow.
- Base64 is encoding, not encryption. Do not use it to hide confidential images.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Image to Base64 runs locally in your browser. Your image stays in your browser and is not uploaded, stored, or sent to ClearUtils.
FAQ
Does Image to Base64 upload my file?
No. The image is read with browser APIs and the Base64 data URI is generated locally in your browser.
Is Base64 encryption for images?
No. Base64 is encoding, not encryption. Anyone with the Base64 string can decode the image data.
When should I use a Base64 image?
Use Base64 for small icons, examples, fixtures, prototypes, or documentation snippets. Larger images are usually better as normal files because Base64 strings are long and harder to cache.
