FAQ

1. Why is the maximum file size limited to 10MB?

The current limit is 10 MB per image, up to 20 images. This bounds browser memory use. Base64 expands the data and an additional copy is needed to display the result. Small icons remain the most suitable use case.

2. Will my files be saved permanently?

No file is uploaded to a conversion server. The browser reads it locally and creates the result in memory. Text and images are not saved in local storage; only conversion settings are remembered. Downloaded results remain on your device until you remove them.

3. Why can't my images be displayed on IE8?

Legacy Internet Explorer implementations have Data URI and image-size restrictions. This tool itself uses modern browser APIs and does not support IE8. Use a current browser, or serve an ordinary image file when supporting legacy clients.

4. Why does drag and drop not work in IE8 and IE9?

The current tool requires modern file and drag-and-drop APIs. IE8 and IE9 are not supported. In a current browser, the file picker is an alternative if dragging a file is inconvenient.

5. How can I ensure my Base64 images are compatible with all devices?

Keep the full Data URI, use the correct MIME type, and test in the browsers or email clients that will display it. A successful Base64 conversion does not guarantee that every application supports the underlying image format.

6. Does my browser or hardware support large Base64 strings?

Limits depend on memory, browser and the application receiving the string. Large strings may slow an editor or page. Split work into smaller batches and prefer image URLs when embedding adds too much data.
