Pixels
Pixels is Macprit's image toolkit: convert between common formats, batch-process a folder of images, and adjust size, quality, and metadata before exporting locally on your Mac.
No universal size or quality promiseConvert between JPG, PNG, WebP, and AVIF. Pixels reads the source image and writes a new file in the format you choose, leaving the original untouched.
AVIF gets its own dedicated guide, covering conversion in both directions plus AVIF-specific options.
Add a batch of images and apply the same format, resize, and compression settings to all of them in one pass, instead of processing files one at a time.
Resize images down, choose a quality and file-size trade-off, and remove or preserve embedded metadata such as camera and location details before exporting.
A dedicated guide walks through exactly how these settings affect the final file size.
The final file size and visual quality depend on the original image and the settings you choose — there is no universal size or quality promise that applies to every photo.
Two images with the same settings can compress very differently depending on their original content and format.
