ToolBox Image vs Squoosh.

Quick comparison

What Squoosh does well

Squoosh, created by Google Chrome Labs, is a polished single-image compressor with the widest codec selection of any browser-based tool. It ships with MozJPEG, libjpeg-turbo, Oxipng, WebP, AVIF, and even niche codecs like JPEG XL and WP2. Its pixel-level side-by-side comparison view — where you can zoom to 400% and toggle between original and compressed — is genuinely useful for quality-critical work. The advanced encoder parameters (effort level, chroma subsampling, denoise, and more) give power users fine-grained control over the output. For someone who needs to squeeze every last byte out of a single image with maximum control, Squoosh is an excellent choice.

Where Squoosh falls short

Squoosh processes one image at a time. There is no batch mode, so compressing a folder of 50 images means 50 separate uploads, 50 separate settings adjustments, and 50 separate downloads. It also does not support HEIC/HEIF input — a significant gap for iPhone users. The interface, while powerful, can be overwhelming for casual users who just want to "make this image smaller" without learning what "chroma subsampling" means. And Squoosh is only a compressor — there is no resizer, cropper, rotator, converter, or any other image tool built in.

What ToolBox Image offers

ToolBox Image is built for workflow efficiency. The flagship image compressor and bulk compressor handle unlimited images in parallel — upload a folder of 200 photos, set a quality level (or a target file size), and download them all as a ZIP. Our target-size compression mode lets you specify an exact file size (100 KB, 200 KB, 500 KB) and the algorithm adjusts quality automatically to hit that target — something Squoosh cannot do.

Beyond compression, ToolBox Image provides a complete image editing ecosystem: a resizer, cropper, format converter, HEIC converter, circle crop tool, image redactor, image to PDF converter, and more. All of these run entirely in your browser with no uploads. For users who regularly work with images — preparing assets for ecommerce, social media, or web publishing — the ability to compress, resize, crop, convert, and redact in one place is a significant productivity gain.

Feature comparison deep-dive

The single biggest practical difference is batch processing. If you need to compress one image at a time with full encoder control, both tools work well — Squoosh gives you more knobs, ToolBox Image gives you a simpler slider. But if you ever need to process more than one image, Squoosh quickly becomes tedious. ToolBox Image's bulk mode processes unlimited images simultaneously, applies consistent settings across all files, and delivers a single ZIP download. For photographers, ecommerce managers, and web developers handling image sets, this is a workflow game-changer.

The second difference is the tool ecosystem. Squoosh is a dedicated compressor — and it does that one thing well. ToolBox Image is a full image workspace. After compressing your images, you can resize them for social media, crop them to a specific aspect ratio, convert them to a different format, or even redact sensitive information — all in the same tool suite. There is no need to switch between different websites or apps. For understanding which format suits your project, see our best image format guide and lossy vs lossless comparison.
