Alternative for Mac
A TinyPNG alternative for Mac
What TinyPNG does well
TinyPNG (Tinify) is known for perceptual compression that keeps PNG, WebP and AVIF looking clean at a fraction of the size. Beyond the drag-and-drop site there's a well-documented API and a Photoshop plugin, which makes it a favorite for websites and design teams. The free web tool allows up to 20 images at a time; Web Pro (US$3.25/month billed annually) lifts that to unlimited with larger files.
If image compression is part of a build pipeline or a team workflow, TinyPNG's API and plugin are a real advantage.
Where Fileknife is different
TinyPNG uploads each image to compress it. Fileknife compresses on your Mac, so nothing leaves the machine and there's no 20-image batch limit or 5 MB free-tier ceiling to work around.
Fileknife is a one-time purchase and can compress to a target size, which is handy for upload forms with a hard limit. It doesn't offer an API or a Photoshop plugin, so for automated or in-design compression TinyPNG remains the better fit.
