Pixtamer
Batch-convert, compress, resize and rename images into web-ready JPEG, PNG, WebP and AVIF

Overview
Drop in a folder of photos or screenshots and get web-ready files out: the right format, size and name, with the real before and after sizes for every image.
Pixtamer is a native Mac app, so it is fast on big batches and never uploads anything.
Features
- Export to JPEG, PNG, WebP and AVIF
- Responsive widths: several sizes of each image in one export
- Reusable presets for the jobs you repeat
- Rename with templates such as {name}-{width}
- Safe exports: originals are never changed and existing files are never overwritten by surprise
- Real before and after file sizes
Privacy
Images are processed on your Mac. Pixtamer is sandboxed with no network access: no account, no analytics, no uploads.
