Frequently Asked Questions
Is my Base64 image data secure?
Yes. All image decoding happens 100% client-side in your browser. No data is uploaded to any server.
Is this Base64 image preview tool free?
Absolutely. This tool is completely free with unlimited previews and no restrictions.
Does this work offline?
Yes, once the page loads, you can preview Base64 images entirely offline without an internet connection.
What Base64 image formats are supported?
All standard formats: PNG, JPG/JPEG, GIF, WEBP, SVG, and BMP Base64-encoded images are supported.
Do I need to include the data URI prefix?
It works with or without the prefix. You can paste “data:image/png;base64,…” or just the Base64 string itself.
Why is my image not displaying?
Ensure the Base64 string is valid and complete. Truncated or corrupted strings will fail to render as images.
Can I download the previewed image?
This tool is for preview only. To download, use a Base64 to Image converter tool that includes download functionality.
How large can the Base64 string be?
No specific limit, but very large images (several MB) may slow down browser rendering depending on your device.
What if I paste non-image Base64 data?
The preview will fail or display nothing. This tool only works with Base64-encoded image data.
Can I preview multiple images at once?
Currently the tool previews one image at a time. Clear the input and paste a new Base64 string to preview another.
