PixtamerVerified on MacBase

Pixtamer turns a folder of photos, screenshots or design exports into web-ready images in one batch: the right format, the right size and a clean file name, with real before-and-after sizes for every file. Drop in images or whole folders, pick a format and size, and export. Everything runs on your Mac. There's no account, no upload and no network access, and your originals are never changed. What it does: • Convert to JPEG, PNG, WebP or AVIF. Reads JPEG, PNG, HEIC/HEIF, WebP, AVIF, TIFF, GIF, BMP and JPEG XL. • Compress with a quality slider, or lossless WebP. Strip metadata or keep it. • Resize to fit a box, to an exact size, or to several widths at once. One source becomes 480w, 960w and 1440w files for srcset, and small images are never upscaled. • Rename with web-safe names ("Homepage Hero (FINAL).heic" becomes "homepage-hero-final.webp"), a suffix, or a template like {name}-{width}w. • Organise output into subfolders by format or by width. • Presets: save a recipe once and apply it to the next batch. • Preview each image before and after, with the actual output dimensions, size and file name. • Safe exports: originals are never touched, and existing files aren't overwritten unless you choose to. One bad file doesn't stop the batch. • Recent Exports keeps a history of what went where. Made for web developers, designers, bloggers and anyone who keeps resizing images for a website, CMS or app. Native SwiftUI app, universal (Apple silicon and Intel), signed and notarized by Apple.
