The hidden cost of image workflows
Modern creators and web teams spend a surprising amount of time on image pre-processing. Convert HEIC photos from iPhone to JPEG, resize for social media, compress for blog uploads, apply a logo watermark, then clean up file names — each step is small, but together they add up to hours every week.
Free online converters create a different problem. Once you upload an image, it sits on a third-party server under whatever retention policy that service has. Confidential decks, original artwork, family photos — anything you'd never knowingly hand over still ends up on someone else's machines.
Why Image Tool+
Image Tool+ solves both problems at once: your time and your privacy.
- Fully local. Images never leave your Mac. Safe for confidential and personal work alike.
- One drop, every step. Conversion, resizing, compression, watermarking, and renaming in a single batch.
- HDR, wide gamut, HEIC, AVIF. Modern formats from iPhone 15 Pro and beyond are first-class citizens.
- VisionKit-powered background removal. One click on macOS 14+, fully on-device.
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.

Technical background
Why we insist on local processing
Online image converters are convenient, but they overlook the special nature of image data. Images carry EXIF metadata — capture time, GPS coordinates, camera model, edit history. Converting a confidential photograph through an online service can leave its precise location on someone else's server.
Image Tool+ resolves this structurally. The app runs inside macOS's App Sandbox with no network access. It cannot reach any file beyond what you explicitly hand to it — this is enforced by the OS, not by trust. "Please trust us" is replaced with "the OS won't allow otherwise."
Why one integrated app
Workflows that string together "convert-only" and "resize-only" tools come with hidden cost. App switching, intermediate files, dropped metadata, inconsistent UI — small frictions that quietly erode your day.
Image Tool+ lets you save the major steps as a single preset. From the second time on, the entire workflow runs from one drop. Your workflow itself becomes an asset.
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.
