Tools

Tools collects small utilities for day-to-day work so they are discoverable in one place. Use the workspace for quick generation, conversion, inspection, and testing tasks that do not need their own application.

Use Tools

• Generate mailto links, QR codes, UUIDs, placeholder text, and passwords.
• Encode or decode Base64, Hex, or Base32 and convert color formats.
• Extract readable document text as plain Markdown, then copy or download it.
• Render Markdown as a styled PDF with a print preset or custom CSS.
• Calculate hashes or encrypt and decrypt text for controlled workflows.
• Convert mixed image batches to JPEG, PNG, WebP, or Base64 HTML in the browser.
• Crop, adjust, annotate, redact, and export an image in the browser.
• Measure a connection or create a temporary endpoint to inspect webhooks.

Check where each task runs before entering sensitive data. Most generators, converters, security helpers, and image operations are interactive page tools. Speed tests, document extraction, and PDF rendering call the Cloud server. Document conversion holds its input and result only in memory; webhook endpoints and request history are stored server-side.

Understand the Tools model

Webhook logs redact common sensitive headers such as Authorization and Cookie, but paths and bodies can still contain private data. Use synthetic payloads when possible.

Convert a document to Markdown

Open Document to Markdown, then select or drop one PDF, Word document, OpenDocument text, RTF, PowerPoint or OpenDocument presentation, .xlsx or OpenDocument spreadsheet, CSV, or EPUB file. The signed-in browser sends the file to the Tools server. The tool previews the result as plain text and lets you copy it or download a .md file.

Documents are limited to 20 MB, filenames to 255 characters, and extracted Markdown to 1 MB. A shortened result is labelled. The converter does not perform OCR, so image-only scans need OCR elsewhere first. Encrypted, password-protected, malformed, and unsupported files return a clear error. Cancelling stops the browser request; the current bounded native conversion may still finish on the server.

The upload and result are never stored by this utility. The authenticated, rate-limited endpoint marks responses as private and non-cacheable. It is documented in the Tools OpenAPI description at /tools/api/openapi.json.

Convert Markdown to PDF

Open Markdown to PDF, enter Markdown, then choose Document, Report, Compact, or Custom. Choosing Custom reveals a complete minimal stylesheet directly below the Markdown editor. Generate the PDF explicitly, review the rendered pages, and download the result. Changing the Markdown, template, or custom CSS marks the existing preview as out of date instead of silently rendering again.

Markdown is limited to 256 KiB and custom CSS to 32 KiB. Custom CSS replaces a preset rather than overriding one and can define print rules such as @page, type, spacing, colors, and tables. Raw HTML remains inert. Markdown images appear as links in the PDF; the server does not fetch them. External stylesheets, fonts, and CSS resource URLs are rejected.

The authenticated and rate-limited /tools/api/markdown/pdf endpoint returns the PDF directly with a private no-store policy. The Markdown, CSS, and PDF are processed in memory and are not persisted. API callers may also combine a preset with CSS overrides; omitting the preset makes the CSS the complete stylesheet.

Convert images in bulk

Open Image Converter, then select or drop any mixture of static images that the browser can decode. The workspace keeps every source in the page and lets you select, remove, or rotate individual previews before export. Nothing is uploaded or persisted. Export settings open automatically while the batch contains images.

Choose JPEG, PNG, or WebP, then optionally limit the maximum width and height. The converter preserves aspect ratios, never enlarges smaller images, and applies the limits after rotation. JPEG and WebP expose quality controls; JPEG also lets you choose the background used for transparent pixels.

Export one image as a direct download or several images in one ZIP. The split menu beside each export action copies complete Base64 HTML <img> tags instead. With an active selection, separate actions export all images or only the selected images. Base64 images are useful in controlled HTML, but uploaded or hosted images are usually more reliable across email editors and recipients.

Input support follows the browser. Vector images are rasterized, animated images become still images, and converted output does not retain source image metadata.

How Tools fits Cloud

Tools owns the utility catalog, browser interactions, speed-test endpoints, and user-owned webhook records. Cloud supplies the shared application shell, identity for stored network tools, settings, lifecycle, and the in-product Help surface.

Find detailed product help

Open Help inside Tools to choose the right utility and review data-handling guidance. Developers can read Application shells, Authentication, and Build typed HTTP APIs for the shared contracts used by the workspace and its server-backed tools.

Run Tools from the terminal

Tools provides a native CLI module. Most commands run locally and do not need a Cloud profile:

cld tools uuid --count 3 --json
cld tools color "#2563eb" --json

Run cld tools help to see the available generators, encoders, security helpers, and speed test. Run cld tools <command> --help for exact inputs and output options.

Document to Markdown and Markdown to PDF deliberately have no dedicated cld tools commands. Signed-in users can use the Tools pages; authenticated integrations can call /tools/api/documents/markdown or /tools/api/markdown/pdf. Neither endpoint fetches URLs or resolves resources owned by another application.
