Convert Base64 strings or files back to visual image files (PNG, JPG, SVG, WebP) instantly. Safe, fast, and completely offline.
This converter is built entirely inside your browser memory sandbox. It utilizes standardized Web APIs to encode and decode text, images, and files completely locally.
Unlike online converters that send your sensitive data and files to external servers, CanvaTools guarantees that none of your documents, credentials, or strings are ever logged or uploaded.
Supports instant visual decoding for PNG, JPEG, GIF, WEBP, BMP, ICO, AVIF, TIFF, and SVG data.
Your image strings are processed entirely in your browser. No image data is ever uploaded or sent online.
Includes dynamic image zoom controls, checkerboard background support for transparency, and quick download features.
Converting Base64 text representations back into visual image files is simple, instant, and secure.
Type or paste the Base64 code string (with or without data:image prefix) into the input textarea.
The tool instantly parses the byte headers and renders the visual preview. Use the zoom controls to inspect dimensions.
Click the Download button to save the converted image file directly to your device with the correct format extension.
Answers to common queries about Base64 decoding, image formats, and security.
Simply paste your Base64 encoded string into the input text area. If the string is a valid image representation, our offline engine will read the file headers and display a visual preview in the output panel immediately.
We support all major web and graphic formats including PNG, JPEG/JPG, GIF, WEBP, BMP, ICO (favicon), AVIF, TIFF, and SVG. The file format is auto-detected from the first few bytes of the decoded data.
Yes! Our decoder automatically detects and strips prefixes like "data:image/png;base64," or other mime prefixes, allowing you to paste either raw base64 code or fully qualified HTML/CSS data URIs.
No. The conversion is performed entirely in client-side JavaScript within your browser session memory. Zero bytes of your images or code are sent to external servers, ensuring complete privacy.
