Frequently Asked Questions
What is a Base64 image?
Base64 encoding converts binary image data into a text string. The full Data URL (data:image/png;base64,...) can be used directly as an <img> src or in CSS background-image — no separate file needed.
Which image formats are supported?
PNG, JPEG, GIF, WebP, SVG, BMP, and any other format your browser supports for reading.
Is there a file size limit?
No hard limit — but very large images produce very long Base64 strings. Files up to ~5 MB work comfortably.
Can I paste a raw Base64 string without the data: prefix?
Yes. The decoder accepts both the full Data URL (data:image/png;base64,…) and a raw Base64 string without the prefix.
