New Features

Split Route

This release brings a new multipart/form-data route for splitting PDF files:

POST /forms/pdfengines/split

It accepts the following form fields:

Key	Description	Default
splitMode	Either intervals or pages.	Required
splitSpan	Either the intervals or the page ranges to extract, depending on the selected mode.	Required
splitUnify	Specify whether to put extracted pages into a single file or as many files as there are page ranges. Only works with pages mode.	false

Thanks @​ps73, @​nodecentral, @​markitosgv, @​wjkoh!

Split Chromium PDFs

The multipart/form-data routes from the Chromium module also accepts the previous form fields for splitting the resulting PDF.

Split LibreOffice PDFs

In the same manner, the multipart/form-data route from the LibreOffice module accepts the previous form fields for splitting the resulting PDFs.

Chore

New Features

Select PDF Engines per Feature

You may now select PDF engines for each feature thanks to new flags:

• --pdfengines-merge-engines - Set the PDF engines and their order for the merge feature (default qpdf,pdfcpu,pdftk).
• --pdfengines-convert-engines - Set the PDF engines and their order for the convert feature (default libreoffice-pdfengine).
• --pdfengines-read-metadata-engines - Set the PDF engines and their order for the read metadata feature (default exiftool).
• --pdfengines-write-metadata-engines - Set the PDF engines and their order the write metadata feature (default exiftool).

⚠️ The flag --pdfengines-engines is deprecated.

Fail On Resource HTTP Status Codes (Chromium)

Like failOnHttpStatusCodes, the new failOnResourceHttpStatusCodes form field tells Gotenberg to return a 409 Conflict response if the HTTP status code from at least one resource is not acceptable.

Resource Network Errors (Chromium)

The new form field failOnResourceLoadingFailed tells Gotenberg to return a 409 Conflict if Chromium encounters any of the following network errors while attempting to load a resource:

• net::ERR_CONNECTION_CLOSED
• net::ERR_CONNECTION_RESET
• net::ERR_CONNECTION_REFUSED
• net::ERR_CONNECTION_ABORTED
• net::ERR_CONNECTION_FAILED
• net::ERR_NAME_NOT_RESOLVED
• net::ERR_INTERNET_DISCONNECTED
• net::ERR_ADDRESS_UNREACHABLE
• net::ERR_BLOCKED_BY_CLIENT
• net::ERR_BLOCKED_BY_RESPONSE
• net::ERR_FILE_NOT_FOUND

Chore

• Updates Chromium to version 130.0.6723.91 (except for armhf).
• Updates Go dependencies.

v8.12.0: 8.12.0

New Features

Bind IP

The new flag --api-bind-ip allows to set the IP address the API should bind to for incoming connections, instead of the default 0.0.0.0.

For instance: --api-bind-ip=127.0.0.1.

Thanks @​dani for the suggestion!

Scope Extra HTTP Headers (Chromium)

You can add an optional scope token to a header value to restrict its application using a regular expression.

For instance:

curl \
--request POST http://localhost:3000/forms/chromium/convert/url \
--form url=https://my.url \
--form-string 'extraHttpHeaders={"X-Scoped-Header":"value;scope=https?:\\/\\/([a-zA-Z0-9-]+\\.)*domain\\.com\\/.*"}' \
-o my.pdf

This new scope token is only processed by Gotenberg and is never sent with the header value.

Thanks @​forg002-ctrl and @​OsoianMarcel for the help!

pdfcpu CLI

In earlier versions of Gotenberg, we used the pdfcpu Golang library directly. However, there wasn't a clean way to terminate the process in case of a timeout, which could lead to resource leaks. We now rely on the pdfcpu CLI, allowing us to effectively handle timeouts, resulting in a more stable PDF engine.

Fix

Webhook Duplicate Trace IDs

Webhook callbacks returned duplicate trace IDs when there were multiple requests pending. This is now fixed.

Thanks @​lrakauskas for the heads up!

v8.11.0: 8.11.0

New Features

Body Limit

You may now set a body limit for multipart/form-data requests, including files downloaded via the downloadFrom form field.
To enable this feature, set the --api-body-limit flag with a string value like 500KB, 5MB, 5GB, etc. There is no limit by default.

New skipNetworkIdleEvent default value (Chromium)

By default, Gotenberg does not wait anymore for the network idle event, significantly speeding up the conversion process. Although Chromium triggers this event heuristically, it is often — if not always — fired too late for page rendering.

Chore

Updates Go dependencies.

v8.10.0: 8.10.0

Compare Source

New Features

Download from URLs

All multipart/form-data routes now accept a form field downloadFrom.

This field accepts a JSON string (e.g., [{"url":"http://localhost:80/","extraHttpHeaders":{"X-Foo":"Bar"}}]) and attempts to download each entry (file) in parallel. URLs MUST return a Content-Disposition header with a filename parameter.

You can configure its behavior using the following flags:

• --api-download-from-allow-list - Set the allowed URLs for the download from feature using a regular expression.
• --api-download-from-deny-list - Set the denied URLs for the download from feature using a regular expression
• --api-download-from-max-retry - Set the maximum number of retries for the download from feature.
• --api-disable-download-from - Disable the download from feature.

Thanks @​aldenquimby, @​tcarsuzanlandytech and @​callumgarven for the help!

Convert Files with a Password (LibreOffice)

The route /forms/libreoffice/convert now accepts a password form field, allowing conversion of password-protected documents.

Thanks @​markusberg for the suggestion!

Health Check with HEAD Method

The /health route now accepts the HEAD method. The only difference from the GET method is that the response body will be empty.

Thanks @​omni-htg for the suggestion!

Fixes

Blank PDF on Errors (Chromium)

The Chromium module now correctly returns a 400 Bad Request if the browser encounters one of the following errors:

• net::ERR_CONNECTION_CLOSED
• net::ERR_CONNECTION_RESET
• net::ERR_CONNECTION_REFUSED
• net::ERR_CONNECTION_ABORTED
• net::ERR_CONNECTION_FAILED
• net::ERR_NAME_NOT_RESOLVED
• net::ERR_INTERNET_DISCONNECTED
• net::ERR_ADDRESS_UNREACHABLE
• net::ERR_BLOCKED_BY_CLIENT
• net::ERR_BLOCKED_BY_RESPONSE

Thanks @​eMerzh for the suggestion!

Error Logging Leaking "File Already Closed"

In some scenarios, such as when using the QPDF engine, the logger was logging irrelevant errors.

New Features

Process Management

Previously, auto-restarts happened at the start of a request, causing noticeable latency.
Now, processes restart after a request, reducing or eliminating latency when the system isn't fully loaded.

Chromium

A conversion now fails with a 400 Bad Request response when Chromium encounters ERR_CONNECTION_REFUSED. Thanks to @​Neirda24 for the heads up!

Key	Description	Default
allowDuplicateFieldNames	Specify whether multiple form fields exported are allowed to have the same field name.	false
exportBookmarks	Specify if bookmarks are exported to PDF.	true
exportBookmarksToPdfDestination	Specify that the bookmarks contained in the source LibreOffice file should be exported to the PDF file as Named Destination.	false

exportOnlyNotesPages	Specify, if the form field exportNotesPages is set to true, if only notes pages are exported to PDF.	false
exportNotesInMargin	Specify if notes in margin are exported to PDF.	false
convertOooTargetToPdfTarget	Specify that the target documents with .od[tpgs] extension, will have that extension changed to .pdf when the link is exported to PDF. The source document remains untouched.	false
exportLinksRelativeFsys	Specify that the file system related hyperlinks (file:// protocol) present in the document will be exported as relative to the source document location.	false
exportHiddenSlides	Export, for LibreOffice Impress, slides that are not included in slide shows.	false

Images

Key	Description	Default
quality	Specify the quality of the JPG export. A higher value produces a higher-quality image and a larger file. Between 1 and 100.	90
