Batch image conversion for Mac.
Image Tool+ is a Mac-only app that batch-converts HEIC, PNG, JPG, and GIF to WebP, AVIF, JPEG XL, and more — with resizing, compression, watermarking, background removal, and renaming in the same pass. All of it runs 100% locally: your images never leave your Mac.

Three steps, done
Batch-converting HEIC, PNG, JPG, and GIF to WebP, AVIF, JPG, and more on a Mac takes three steps: drop your images, pick an output format, and hit Start.
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.
The User Guide walks through every setting and handy workflow, with screenshots.
Feature highlights
Beyond format conversion and resizing, Image Tool+ handles before/after comparison, HDR and wide-gamut preservation, background removal, batch watermarking, and metadata editing — all in one window.

Slide to compare,
Drag the center divider and inspect original vs converted output at the pixel level. Decide on quality before you commit to the file, not after.
"Bump quality a bit." "Actually we can compress harder than I thought." Those calls become eye-level decisions, not number guesses.

It understands HDR —
Most converters quietly drop HDR and color profile information (Display P3 / Rec. 2020) during conversion. The vivid tones and tonal range from your iPhone 12+ shots collapse into dull sRGB.
Image Tool+ reads and preserves transfer curves, peak luminance, CICP, and gain maps, writing them out at each format's full expressive range — 10-bit YUV 4:4:4 / 4:2:0 and more. Non-negotiable for professional photographers, video creators, and print designers.
VISIONKIT · ON-DEVICE
Detect any subject,
Powered by Apple's VisionKit, subjects are detected with high precision and the background is cleanly removed with a single click. No external AI service — your Mac's Neural Engine handles it locally and instantly.
Perfect for profile shots, product photos, and social-media eye-catches. (Requires macOS 14 Sonoma or later)
POSITION · SIZE · OPACITY · OFFSET
Watermarks,
Burn a logo or any watermark image into your output, in batch. Position, size, opacity, and offset are all fine-grained, and watermarking works on still images and animated GIF/APNG/WebP alike.
Theft prevention, brand consistency, photo books — every image in the batch gets the same treatment, automatically.
Watermark Settings
Enabled
EXIF · IPTC · XMP · GPS
Metadata,
Edit Copyright, Artist, Date taken, GPS — across hundreds of images at once. Stamp credits on a delivery batch. Strip GPS before posting to social. Run it in passing.
EXIF, IPTC, XMP, and GPS blocks are all handled in one place, and HDR metadata stays intact while you edit.
Support
The Image Tool+ User Guide covers everything in detail, with screenshots: settings and defaults for each format, HDR and gain maps, batch renaming, preferences, and keyboard shortcuts.

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 and does everything from reading to writing images on your Mac. Nothing is sent to a server for conversion, and it works fully offline.
