appkiro.comExamples: AVIF images saved from Figma, exports from Photoshop, or assets downloaded from your CMS.
Encode a AVIF file into Base64, ready to paste into HTML, CSS, JSON, or a data URL. AVIF compresses aggressively, making encoded payloads small for hero images and photographic assets.
Inlining cutting-edge photo assets into static demos targeting modern browsers, or distributing AVIF fixtures.
For pure-text payloads use the Text to Base64 tool.
Does the file leave my browser?
No. Encoding runs in your tab — nothing is uploaded.
Is there a file size limit?
Practical limits depend on browser memory; encoding is comfortable up to ~50 MB.
Will Safari render the result?
Recent Safari versions support AVIF; older ones do not. Provide a fallback for older clients.
