TinyPNG

YES

Replaceable in one session with an AI coding agent.

Compresses PNG and JPEG files by reducing colours and stripping metadata, usually cutting file size by half with no visible difference.

Promptfree, for everyone, and the only version there is

Compress images in your build.

STACK
- sharp for resizing and conversion, plus oxipng and mozjpeg for the final squeeze

THE PIPELINE
- Resize to the largest size actually displayed, first — this saves more than any compression setting
- Convert to AVIF and WebP, keeping the original format as a fallback
- Strip metadata, but keep the colour profile or colours will shift

SERVING
- A picture element with AVIF, WebP and the fallback in that order
- width and height attributes always, so the page does not jump while loading

CHECKING
- Fail the build if any image over 200KB reaches the output directory
- That single rule does more for page weight than any tool

Include the build step, the picture markup and the size check.

What you lose

Compression settings tuned across millions of images so the default is nearly always right
An API and plugins for the tools designers already use
Nothing to install or run

If you would rather not build

Squoosh CLI, for one-off work

Why this verdict

our own opinion · changed only by a person

93/100

Verdict yes at 93. sharp does this in a build script, and resizing before compressing saves more than the compressor ever will.
