Squoosh Alternative for Batch Image Compression (Free, No Upload)

Privacy

A tie. Squoosh's own README says it "does not send your image to a server" — compression runs locally in the browser, and so does ours. Both sites use analytics for page statistics; neither receives your images.

Batch compression

Our compressor accepts many images at once and lets you download the results individually or as a single ZIP. The Squoosh web app compresses one image at a time, and its CLI for batch work has been deprecated.

Codec control

Squoosh wins. It offers MozJPEG, WebP, AVIF, JPEG XL, OxiPNG and more, each with detailed encoder options and a live side-by-side preview. Ours offers JPEG, PNG and WebP output with a simple quality slider.

Resizing

Both can resize while compressing. Ours resizes by percentage, fixed dimensions, max width or max height, applied to the whole batch.

Working offline

Squoosh can be installed as a web app and keeps working without a connection. Our compressor needs the page to load once, after which compression itself needs no network for as long as the tab stays open.

Price

Both are free with no account.

Use Squoosh when…

you are optimising one hero image or a few key assets and want to tune AVIF/MozJPEG settings while comparing quality side by side.

Use our compressor when…

you have a folder of product photos, screenshots or camera images and want them all smaller with the same settings, in one ZIP, in a few clicks.

Add images

Open the image compressor and drop in as many JPG, PNG or WebP files as you need.

Pick settings once

Choose the output format and quality, and optionally a resize rule — it applies to every image.

Download the ZIP

Save every compressed image in one archive, or download them one by one.

Does Squoosh upload my images?

No. Squoosh processes images locally; its README says it collects analytics such as visitor data and before/after file sizes, but not the images themselves.

Can Squoosh compress multiple images at once?

Not in the web app. The batch-capable Squoosh CLI is marked as no longer maintained on npm.

Which format should I choose for the web?

WebP is the safe default: every current browser supports it and it is usually much smaller than JPEG at similar quality. Keep PNG for images that need sharp edges or transparency.
