operation = Image to Data URL Converter; output = data-url.pngThe browser recalculates pixels using this rule: Convert an image to a metadata-free PNG Data URL locally, preview it and copy the generated value for HTML or CSS. After checking the preview, download data-url.png; the source file is not overwritten.

Data URL guide
Convert an image into a copyable PNG Data URL
After you choose a JPEG, PNG, or WebP image, the tool redraws it on a browser canvas and produces a PNG Data URL beginning with data:image/png;base64,. Neither the image nor the result is uploaded to 321Kit.
Use the result in HTML or CSS
Place the complete value in an img src attribute or inside CSS background-image: url("…"). A Data URL embeds image bytes directly in text; it does not create a public hosted image address.
Why the output is always PNG
The supported source image is drawn onto a canvas and encoded again as PNG. JPEG and WebP inputs therefore produce a PNG MIME type, without retaining the original filename, compression method, or removable metadata.
When a Data URL is the wrong choice
Base64 increases text size, and an inline resource cannot be cached separately like a normal image URL. It can suit small icons or self-contained examples; large or repeatedly used assets usually belong at a regular file URL.
Frequently asked questions
Does this create a shareable hosted image URL?
No. It creates an inline Data URL containing the image bytes. Nothing is uploaded, and no third-party-accessible hosting page is created.
Which input formats are supported?
JPEG, PNG, and WebP files are accepted up to 30 MB and 40 megapixels. The generated Data URL always uses PNG.
Does conversion preserve image metadata?
No. The image is redrawn and encoded as a new PNG result, so source metadata such as EXIF is not copied into the generated value.
