Frequently asked questions
Where do I get a Base64 image string?+
They commonly appear as data: URLs in HTML and CSS, in JSON API responses, or from an image-to-Base64 encoder. Paste the whole string — with or without the data:image/... prefix — and the file is rebuilt in your browser.
Does it need the "data:image/..." prefix?+
No — it works either way. With the prefix, the format is read directly from it; without it, the format is detected from the decoded bytes themselves.
Which image formats are detected?+
PNG, JPG, WebP and AVIF — the same four formats the rest of the image cluster supports.
Is my data uploaded anywhere?+
No. Decoding runs entirely in your browser — nothing is sent to a server.
