Frequently asked questions
What formats are supported?
PNG, JPEG, GIF, WebP, and SVG. The tool auto-detects the format from the Base64 data.
Do I need the data:image prefix?
No. You can paste the raw Base64 string or the full data URI (with or without the data:image/... prefix). Both work.
Is there a size limit?
No hard limit, but very large images (10MB+) may be slower to decode. For best results, keep strings under a few megabytes.
Is my data stored?
No. Everything runs locally in your browser. Your Base64 data is never sent to any server.
