Convert files without leaving Claude.
Attach a file, say what you want. ChangeThisFile covers 1,000+ supported conversion routes, translates documents with the layout intact, pulls tables into Excel, and compresses files to an exact size — right in the conversation. The one-click connector currently needs no account; verified Free accounts include 25 shared MCP + REST conversions monthly.
What Claude can do with your files
Claude is brilliant with words but can't hand you back a changed file. With the ChangeThisFile connector, it can: the file goes out, the converted, translated, extracted, or compressed file comes back as a download link — in the same chat.
1,000+ conversion routes
Free developer tier. HEIC → JPG, DOCX → PDF, MP4 → MP3, CSV → XLSX, EPUB → MOBI, and hundreds more. Verified Free accounts include 25 shared MCP + REST conversions monthly.
Translate documents
$4.99 per file, free preview. DOCX, PPTX, XLSX, PDF and more — translated in place, so layout, tables, images, and styling survive. 100+ languages.
Tables → Excel
$3.99 per file, free preview. Every table in a PDF or screenshot, extracted into a clean multi-sheet spreadsheet.
Compress to exact size
Free, daily limit. "Under 5MB for the upload form" — PDF, images, or video shrunk to a byte target, honestly reported if the target is impossible.
Set it up once
One click from the Claude connectors directory. Or manually: Settings → Connectors → Add custom connector → https://changethisfile.com/mcp. Claude Code: claude mcp add --transport http changethisfile https://changethisfile.com/mcp
The one-click connector needs no account for your first 25 conversions each month (per network). Clients that support bearer credentials can add a verified Free key; its 25-use monthly allowance is shared with REST.
Claude picks the right tool, runs the job, and returns your download link. Paid jobs show a free preview first — pay only if you want the full file.
Things people ask Claude
Questions
Is it free?
Verified Free developer accounts include 25 format conversions per month shared across MCP and REST. Compress-to-size has a daily limit. Translation ($4.99) and table extraction ($3.99) run immediately and show a free preview; you pay only to download the full result.
What happens to my files?
Files are processed over an encrypted connection and deleted automatically — inputs, previews, and unpaid outputs within 24 hours; paid outputs after 7 days so you can re-download. Your files are never used to train models.
Do I need an account?
Not to start: the connector converts up to 25 files per month per network without an account. After that, general format conversion needs a free verified API key (25 conversions/month shared across REST and MCP) — the key-required reply spells out the two-step signup. Paid jobs still check out as a guest.
What's a "community connector"?
Connectors in the Claude directory are either community (reviewed through Anthropic's automated submission process) or verified (a deeper quality tier). ChangeThisFile is a community connector — the same server also powers our public API and web converter.
What are the limits?
Verified Free accounts include 25 conversions/month shared across MCP and REST, at 10/minute per account. Anonymous conversion is 25/month per network and 5/minute/IP. Translation is up to 50 MB and 10/day, table extraction 20 MB and 10/day, and compression 100 MB and 3/day.
Does it work outside claude.ai?
Yes — it's a standard MCP server, so it works in Claude Code, Claude Desktop, Cursor, and any MCP-capable client. See the connector docs for setup in each.
