Three steps, done
Drop your images
Drag a stack of files (or a whole folder) from Finder.
Pick output format
WebP, AVIF, PNG, JPG, and more. Set resize, watermark, and rename in one go.
Hit Start
Done in seconds on Apple Silicon — even hundreds of images at once.
Key features
1. Batch conversion — hundreds of files in a single drop
Convert HEIC, PNG, JPG, GIF, TIFF, PSD, PDF, and more, into WebP, AVIF, PNG, JPG, GIF, HEIC, TIFF, and BMP. Drag a stack of files from Finder. The app processes them in parallel on Apple Silicon, finishing without hesitation even at hundreds of images.
2. HDR & wide color gamut support
Most image converters silently drop HDR and color profile information (Display P3 / Rec. 2020) during conversion. The vivid tones and tonal range from your iPhone 12+ photos collapse into dull sRGB.
Image Tool+ keeps HDR and color profile metadata intact. For professional photographers, video creators, and print designers, this is non-negotiable.
3. Background removal (macOS 14+)
Powered by Apple's VisionKit framework, you can extract subjects from backgrounds with a single click. No external AI service. The Neural Engine on your Mac handles it locally and instantly. Perfect for profile pictures, product shots, and social media posts.
4. Watermarks
Burn in logo images or text into the output, in batch. Position, size, and opacity are fully configurable, and watermarking works on still images and animated GIF/APNG/WebP alike. Useful for theft prevention, brand consistency, and assembling photo books.
5. Smart rename
Combine sequential numbers, capture dates, and prefixes/suffixes for batch renaming. "IMG_1234.HEIC" becomes something meaningful like "2026-05-02_kyoto-trip_001.jpg" instantly.
6. AVIF QuickLook plugin included
Out of the box, macOS has limited Finder thumbnail and QuickLook support for AVIF. Image Tool+ ships with a QuickLook plugin so you can preview AVIF files instantly with the spacebar.

Why local processing
Images carry EXIF metadata — capture time, GPS coordinates, camera model. Online converters can leak that data to a third-party server. Image Tool+ runs inside macOS's App Sandbox with no network access: "trust us" is replaced with "the OS won't allow otherwise."
FAQ
Q. How is this different from a free online converter?
The biggest differences are privacy and speed. Online services upload your images and depend on your connection. Image Tool+ runs locally, so on Apple Silicon even hundreds of images finish in seconds, and your images never leave the device.
Q. Does it run on both Apple Silicon and Intel Macs?
Yes. It's a Universal Binary running natively on both. Apple Silicon (M1/M2/M3) shows particularly large speedups in batch jobs.
Q. System requirements?
macOS 11 Big Sur or later. Background removal requires macOS 14 Sonoma or later.
