• New: The Preview window and the Fine-tune window are now one window. Beyond batch conversion, you can change the settings of each image in the side panel and finish your images one by one. "Apply to All" copies the settings to the main window. • Preview window: Slider and 2-Up work with every format, and when reducing colors, 4-Up compares three color counts side by side. • Preview window: Choose the background (Checkerboard / White / Black and more). The view, background and panel carry over to the next window you open. • Preview window: Zoom now lives in the toolbar, and ⌘-scroll and pinch zoom also work in the color-reduction 2-Up / 4-Up. • "Fine-tune…" opens a window for each selected image, with no limit. "From Video…" also opens in the Preview window, and the limit on video frames has been removed.

• New: Color reduction. PNG "Mode" now offers Lossless / Lossy (256 colors) / PNG-8 (Reduce Colors), and WebP and GIF can also be saved with a reduced-color palette. • New: Fine-tune window. Compare color-reduction results side by side, edit the palette, and make APNG / GIF from animations and videos. • New: Trim Margins. Automatically cuts away the plain background (such as white) around the subject, with a margin, a transparent background, and an Output Size option to enlarge the result to the original size, center it on the original canvas, or center it on a canvas of a fixed width and height (placing the subject as is or enlarging it to fit). • New: TIFF Compression (Auto by default: LZW for 8-bit, ZIP for 16-bit, both lossless). HDR photos now stay HDR when saved as TIFF. • Your previous PNG "Lossy compression" setting carries over: on → Lossy (256 colors), off → Lossless. • Fixed an issue where the watermark was sometimes not added. • Fixed iPhone HDR photos looking brighter than the original on some displays after converting to HEIC / AVIF / JPG. • Fixed several HDR issues on macOS 14 and earlier (brightness, and HEIC turned sideways). • Preview window: faster zooming of large JPEG XL images, and more accurate brightness for HDR photos.

This update adds JPEG XL import and export (experimental), and a new "Auto" option for AVIF bit depth that picks the best setting based on the source image. The preview window has been reworked: HDR images are now displayed, HEIC and AVIF HDR images are shown at original quality, and zooming and viewing large images is significantly smoother. This release also brings smoother file list scrolling, lower memory usage during AVIF conversion, a fix for a progress bar that could get stuck before reaching 100%, and a refreshed window design. The minimum supported macOS version is now macOS 11. * JPEG XL support is experimental. * We are gathering feedback on HDR support — please let us know what you think.
