Whether you received a HEIC photo you need as JPEG, a PDF you need as a Word document, or a video you want to extract audio from — file conversion is one of the most common tasks on any computer. The good news: your Mac can handle many of these conversions already. The better news: there are tools that make it effortless.
Method 1: Built-In Tools (Images & Documents)
🖼 Converting Images with Preview
Preview is the built-in image and PDF viewer. It can convert between a handful of image formats.
- Open your image file in Preview (double-click usually works)
- Go to File → Export
- Click the Format dropdown and choose your target (JPEG, PNG, TIFF, or HEIC)
- Adjust quality if available, then click Save
Limitation: Preview only supports a few image formats. It cannot convert to WebP, BMP, or GIF. It also cannot handle video, audio, or document conversion.
📄 Converting Documents with Pages, Numbers & TextEdit
Apple's productivity apps can export to a few formats.
- Open the document in Pages, Numbers, or TextEdit
- Go to File → Export To
- Choose your target format (PDF, Word, RTF, Plain Text)
- Click Save
Limitation: You cannot convert from PDF to Word this way. Pages can only export documents it created. For PDF-to-DOCX, you need a dedicated tool.
Method 2: Online Converters (Quick but Risky)
Websites like CloudConvert, Zamzar, or Convertio let you upload a file and download the converted result. They work in a pinch, but come with serious trade-offs.
Pros
- ✓ No software to install
- ✓ Works on any device
- ✓ Supports many formats
Cons
- × Your files are uploaded to unknown servers
- × File size limits (often 100 MB max free)
- × Slow — depends on upload and download speed
- × Many add watermarks or limit free conversions
- × Requires internet connection
Privacy warning: Never upload sensitive documents (contracts, tax forms, medical records, financial data) to online converters. You have no control over where your files end up or how long they are stored.
Method 3: A Dedicated Converter App (Best of Both Worlds)
If you regularly need to convert files — especially across different types like documents, images, audio, and video — a dedicated converter app eliminates the hassle of juggling built-in tools and the privacy risks of online services.
ConvertDrop is a native Mac app that handles 38 formats across 6 categories with simple drag-and-drop. Everything runs locally on your Mac — no internet needed, no files uploaded anywhere.
