File upload across 9 tools — load a file straight into JSON Formatter, XML Formatter, JSON ↔ XML Converter, Markdown Editor, Code Beautifier, Code Minifier, HTML to JSX, Word Counter, and Base64. Click to browse or drag and drop onto the editor.

DevSavr file uploads raised from 10MB to 100MB per file, with up to 500MB per room and a progress bar for every transfer.

DevSavr redesigned as a chat-style room — one composer for both text and files, drag files anywhere onto the panel, and a message list that scrolls on its own instead of pushing the page down.

DevSavr now lets you name your device, expand long text items, drop several files at once, and confirms before destroying a room.

Larger inputs across the formatting tools — the limit went from 500KB to 2MB for XML Formatter, JSON ↔ XML Converter, Code Beautifier, and Code Minifier.

Text typed into DevSavr is no longer lost when a message fails to send, and items shared while a device was disconnected now reappear when it reconnects instead of being missed.

Uploads larger than 250KB no longer fail with an unhelpful error — the request size limit now matches what the tools actually accept.
