Compress. Convert. Ship.

Smaller files. Same good looks.

Three steps, no learning curve.

Drop, tune, export. The preview shows you the result as you go.

1

Drop your images

Drag a file, a selection, or an entire folder onto the window.

2

Tune the recipe

Pick a format, compression and size — the preview updates live.

3

Export

One image or the whole batch, to a folder of your choice.

Everything you need to ship an image.

The essentials, done well — one recipe, applied to one image or a thousand.

Three ways to compress

Dial in Quality by hand, hit a Target size budget automatically, or let Web-optimized choose in one click.

7 formats

JPEG, PNG, WebP, AVIF, HEIC, TIFF and GIF — including modern codecs that shrink far below JPEG.

Live before/after

A pixel-for-pixel compare slider that jumps to 100%, so you see what compression costs — no guessing.

Crop Studio

Crop, rotate, flip and straighten with a proper editor — not a fiddly afterthought.

Resize & rename

Longest edge, width, height, fit-within or percentage — and rename on export with a prefix or suffix.

Presets & metadata

Save a recipe once and reuse it. Keep EXIF, or strip GPS & camera info on the way out.
