Base64 to Image Decoder — Convertir Data URL to PNG Free

Turn Base64 strings and data URLs back into downloadable image files with our free Base64 to image decoder on XConverters. Paste encoded text, click decode, preview the result, and save the image — all dans votre navigateur. Aucun compte, aucun envoi, entièrement gratuit.

Ce que fait cet outil

API responses, HTML snippets, and database dumps sometimes store images as long Base64 strings. You need a quick way to inspect and save them without writing a script. Our decoder accepts raw Base64 or full data:image/...;base64,... URLs, reconstructs the binary image, shows a preview, and lets you download the file.

Decoding runs entirely dans votre navigateur on XConverters. Sensitive screenshots, user avatars, and internal diagram exports never travel to a server, which makes this tool safe for support engineers and developers handling production data.

The workflow is simple: paste, decode, preview, download. Validation catches malformed input so you know when padding or prefixes need correction. Free unlimited use with no registration.
