Encode an original PNG, JPEG or WebP image as a data URL or raw Base64. Preview the image, copy the complete output or download a text file, entirely in your browser.
Your image is never uploaded to any server; all encoding is completed locally in your browser. Original file bytes, including metadata, are preserved. A local worker keeps encoding separate from the interface, and no account or saved image history is needed.
No. Base64 represents binary bytes as text. It generally increases size by about one third, with more overhead for tiny files and data URL prefixes. Anyone with the encoded text can decode the original file, including its metadata.
Static PNG, JPEG and WebP images up to 10 MiB, 40 megapixels and 16,384 pixels per side. The browser must be able to decode the image for preview. SVG, GIF, AVIF, HEIC and detected animated PNG/WebP are not supported in this version.
Raw Base64 contains only the encoded bytes. A data URL adds a prefix such as data:image/png;base64, so a compatible application knows the content type. Both use standard padded Base64 without inserted line breaks.
Yes. The text preview displays at most 50,000 characters to keep the interface responsive. Copy full output and Download TXT use every character, without added line breaks. If clipboard access fails for a truncated preview, download TXT instead.
The image preview follows the browser’s orientation handling and is scaled for display, but encoding preserves the original bytes exactly. It does not resize, re-encode or remove metadata. Remove metadata before encoding if it should not be included.
Changes clear old results and downloads. Stop terminates the worker and discards partial output. Encoding has a five-second response limit. Clear and leaving the page release application-held image data.
