Help & Frequently Asked Questions

Docutomic is a modern, free, and privacy-first online PDF toolkit and Image to PDF converter engineered to run entirely inside your modern web browser. Unlike traditional online document tools that upload your private files to remote cloud servers, Docutomic utilizes high-performance browser APIs and WebAssembly to process, convert, edit, and compile documents directly on your device. With Docutomic, you can convert JPG, PNG, and WebP images to PDF, customize page margins and layouts, change PDF background colors (including white-to-black and black-to-white color inversion for dark mode and eco-printing), merge multiple PDFs, reorder or delete pages, and compress documents under strict size limits like 200KB—all 100% free with no watermarks, no registration, and absolute data confidentiality.

To convert an image to PDF using Docutomic, follow these three simple steps:

1. Upload Your Images: Drag and drop your JPG, PNG, or WebP pictures into the visual workspace, or click "Upload Images" to select files from your computer or phone.
2. Customize Page Settings: Arrange the order of images using thumbnail previews. Adjust page size (A4, US Letter, or Fit to Image), choose orientation (portrait or landscape), set margins, and configure image fit (contain or fill).
3. Create & Save PDF: Click the "Create PDF" button. Docutomic renders and compiles your multi-page or single-page PDF document locally in milliseconds. Click download to save your new PDF instantly without waiting for cloud uploads.

Yes, you can easily change your PDF background colour with Docutomic. Standard PDF documents and digital whiteboards often feature glaring white backgrounds that cause eye fatigue during extended reading, while dark-themed PDFs waste ink when printed. Docutomic provides a dedicated Change PDF Background Color tool that allows you to tint white pages with soothing ergonomic shades (such as warm beige, soft cream, or sepia), switch documents to an eye-friendly dark mode, or use our smart color inverter to transform black or dark backgrounds into ink-saving, printer-ready white backgrounds. The color is placed cleanly behind your document content, keeping text crisp and vector graphics sharp.

To change your PDF background colour using Docutomic:

1. Open the Change PDF Background Color tool on Docutomic.
2. Upload your PDF file by dragging it into the drop zone or clicking to browse your device.
3. Select your preferred background color from ergonomic preset palettes (such as Warm Cream, Antique Beige, Sage, or Charcoal Dark Mode), or use the custom color picker to specify an exact HEX code. You can also toggle the PDF background colour inverter to convert black backgrounds to clean white.
4. Inspect the live preview to verify legibility across all pages, then click "Download PDF" to export your recolored document instantly.
