Available Tools
Choosing the Right Workspace for Your Workflow
Pick a dedicated editing workspace based on your task, file type, and how much editing you need:
Document Review & Annotation
Need to sign, black out sensitive figures, or review multi-page PDFs? Use the PDF Editor to draw and add notes directly on the document.
Photo Retouching & Graphics
Need colour grading, filters, fine rotation, or drawing on a picture? Use the Image Editor for fast, precise photo editing.
Distraction-Free Writing
Drafting an article, a README, or notes? Use the Markdown Editor with a live side-by-side preview and automatic local saving.
Universal Compatibility Across Standard Files
All format parsing, rasterization, and encoding occur client-side without proprietary software licenses.
Lossless & Optimized Delivery
Direct client-side streams allow instant multi-megabyte exports with zero waiting queues or server rate limits.
Frequently Asked Questions
What makes these editors different from single-action utility tools?
Quick tools do one job and finish. Our editors are full workspaces — you can undo and redo, adjust settings freely, watch the result update live, and keep working for as long as the tab stays open.
Which editor should I choose for modifying contracts or legal documents?
Use the PDF Editor. You can black out confidential passages, add a signature or initials, draw freehand notes, and fill out flat PDF forms — without needing Adobe Acrobat.
Can I use the Image Editor for social media graphics and photo retouching?
Yes. The Image Editor has locked cropping for common social media shapes (1:1, 16:9, 4:5), sliders for brightness, contrast, colour, and warmth, brush tools for small touch-ups, and one-click filter presets.
How does the Markdown Editor handle technical documentation and code blocks?
The Markdown Editor shows a live side-by-side preview as you type. It supports tables, checklists, footnotes, and coloured code blocks with syntax highlighting for most programming languages. When you finish, save it as a Markdown file, an HTML page, or a print-ready PDF.
Is any of my document or text data sent to third-party servers?
Never. Your keystrokes, images, and document data stay in your browser's own memory and local storage. Nothing is logged, transmitted, or backed up to a remote cloud.
