What changes when Claude can handle your PDFs
With this desktop extension, you ask Claude in plain words, it sends the file to the Avanquest PDF API, and the result lands at the path you named on your computer. Each input file can weigh up to 10 MB, and Avanquest deletes processed results from its servers 10 minutes after completion.
Get an editable copy. Ask for a Word version of a report and pdf_convert_to_word produces the .docx; PowerPoint, Excel, plain text and JSON follow the same pattern.
Assemble and trim documents. pdf_merge joins files in the order you give, pdf_split cuts one into separate parts, and the page tools delete, rotate or resize pages.
Prepare a file for sharing. pdf_compress shrinks it at the quality level you choose, pdf_password_protect locks it, and pdf_add_watermark stamps text or an image such as a CONFIDENTIAL mark at 45 degrees.
Now the limits. Each input file is capped at 10 MB and passes through Avanquest's servers, which delete results 10 minutes after processing. Four of the listed tools have no description in any source, so this page says nothing about them. And nothing runs on its own: no tool reacts when a file appears in a folder. That kind of trigger belongs to automation platforms, covered from the Integrations hub.
Five words before you start
The vocabulary around this extension, briefly.
- Connector
- The link you set up once between Claude and an outside service, so Claude can use it while it answers you in a conversation.
- Tool
- One named action the connector gives Claude. Claude decides by itself which tools to call, and the directory lists them by name.
- Authorization
- The access you grant once so Claude can use a service. For this extension, it is the Avanquest API key you paste during setup.
- Approval
- The confirmation Claude waits for before an action that changes something, shown in the conversation at the moment it applies.
- MCP
- The shared standard behind connectors: it lets an assistant such as Claude call an outside service like the Avanquest PDF API.
Set up Avanquest PDF API Extension in three steps
- 01
Find the extension in Claude
In Claude Desktop, open the settings, go to Customize, then Connectors, and look up Avanquest PDF API Extension. It is a desktop extension, installed on Claude Desktop. On Team or Enterprise, an Owner or Primary Owner enables it first.
- 02
Start the connection
Click Connect on its row and provide what the service asks for, here an Avanquest API key rather than a web sign-in. If the extension stops answering later, Disconnect it and connect it again.
- 03
Know what the access covers
The service, not Claude, decides what the access reaches. Here, files you point Claude to are uploaded to the Avanquest PDF API for processing, under Avanquest's privacy policy, then the result is saved locally.
The 22 tools, by what they do to a file
Avanquest PDF API Extension gives Claude 22 tools: 1 that read your account, 17 that change something in it, and 4 no official source describes.
One reads, seventeen produce a new document, four remain unexplained. Tool names stay as Claude shows them.
- 1 read
- 17 write
- 4 not documented
What Claude reads (1)
1 toolOne tool that inspects a PDF and returns information, without producing a new file.
pdf_analyze_tag
Inspects a PDF for its tags, forms, signatures and attachments and reports what it finds. Avanquest documents analysis, not a modified copy.
What Claude produces or changes (17)
17 toolsSeventeen tools that create a new file from yours and save it to a path. No source describes a confirmation for them, so the rule further down applies.
pdf_convert_to_word
Approval: see the ruleTurns a PDF into an editable Word document and saves the .docx where you asked. Avanquest's own example converts a report and drops the result next to it.
pdf_convert_to_powerpoint
Approval: see the ruleRebuilds a PDF as a PowerPoint file you can edit slide by slide, saved to the path you give.
pdf_convert_to_excel
Approval: see the ruleExtracts a PDF into an Excel workbook, so figures trapped in a document become cells again.
pdf_merge
Approval: see the ruleJoins several PDFs into one, in the order you list them, and writes the combined file to the location you choose.
pdf_compress
Approval: see the ruleShrinks a PDF at a quality level you pick, then saves the lighter copy alongside or wherever you say. Avanquest's example uses medium quality.
pdf_split
Approval: see the ruleCuts one PDF into separate files, so a long document becomes several smaller ones you can send independently.
pdf_to_text
Approval: see the rulePulls the text out of a PDF, optionally from selected pages, and saves it as a plain-text file. Avanquest's example extracts pages 1 to 5 of a book.
pdf_delete_pages
Approval: see the ruleRemoves the pages you name from a PDF and produces the shortened document as a new file.
pdf_rotate
Approval: see the ruleTurns pages of a PDF so sideways scans read the right way up, and outputs the corrected document.
html_to_pdf
Approval: see the ruleConverts an HTML file into a PDF, which is handy for archiving a page or a generated report in a fixed format.
img_to_pdf
Approval: see the ruleWraps an image into a PDF document, useful when a form or a portal accepts only that format.
txt_to_pdf
Approval: see the ruleConverts a plain-text file into a PDF so notes or logs travel in a format nobody edits by accident.
pdf_password_protect
Approval: see the ruleAdds password protection to a PDF and saves the locked version, so only people with the password can open it.
pdf_unlock
Approval: see the ruleRemoves existing protection from a PDF and produces an unlocked copy. Avanquest lists it next to password protection as its counterpart.
pdf_resize
Approval: see the ruleChanges the page size of a PDF and writes the result as a new document, one of the three page edits Avanquest lists.
pdf_to_json
Approval: see the ruleConverts a PDF into JSON, a structured format other software can read, and saves it to the path you give.
pdf_add_watermark
Approval: see the ruleStamps custom text or an image across a PDF and saves the marked copy. Avanquest's example puts a red CONFIDENTIAL at 45 degrees.
Undocumented (4)
4 toolsThe directory lists these four names and nothing else. No Avanquest page describes them, and we will not guess from a name.
pdf_insight
This name sits in the directory list and nowhere else in Avanquest's documentation, neither on its MCP page nor in its feature list. What it takes as input and what it returns are not stated by any official source.
pdf_document_extract
Listed by the directory, absent from the feature list Avanquest publishes for the extension. No official text explains its input, its output or whether it touches the original file in any way.
pdf_ocr
The name appears in the directory, yet Avanquest's MCP page and the project's README never mention it. Inferring a capability from the name alone would be guesswork, and this page does not do it.
sign_pdf
Another name the directory shows with no matching sentence anywhere official. The feature list, the usage examples and the privacy section of Avanquest's documentation stay silent about it too. No source says whether it reads a document or changes one, and the general approvals rule is all that covers it.
What Claude checks with you first
By default, Claude stops and asks before each action it carries out on an account for someone, right in the conversation.
On Team and Enterprise, owners decide whether members may let some actions through without a prompt each time, and they can limit what a connector may do for the whole organization, for example keeping reading and blocking writing. Claude works with the rights of the person connected and nothing beyond. With this extension, the practical question is what leaves your computer: every file Claude processes is uploaded to the Avanquest PDF API, and results stay on Avanquest's servers for up to 10 minutes.
Which plans include it
None of the 819 sheets in the official directory shows plan availability. That answer is published nowhere, connector by connector.
The general rule is public: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, while desktop extensions like this one install on Claude Desktop. On Team and Enterprise, an Owner or Primary Owner enables a connector before members use it. For the live state, check this extension's sheet in the official directory.
Where this extension stops
A connector is not an automation. Claude calls these tools while it answers you, so nothing happens when a PDF lands in your downloads folder.
The partner badge in the directory is not a security audit, and Anthropic states on every sheet that it neither picks a publisher's tools nor guarantees their behavior. Only Avanquest documents this extension; no Claude help page covers it. Avanquest also recommends a personal preference telling Claude to discover its tools at the start of each conversation involving files. The same directory rules apply on the Claude affinity connector page.
