Squoosh
A browser-based image compression tool with manual parameter adjustment and the ability to compare the result with the original.
Overview
Squoosh
Squoosh AI Description
Squoosh is a browser-based image compression tool developed by Google. The service's main feature is that all processing happens locally on the user's device, without sending files to remote servers. This ensures complete privacy and instant speed.
The tool supports popular image formats: JPEG, PNG, WebP, AVIF, and MozJPEG. Users can upload a file, adjust compression settings manually, or rely on automatic mode, then compare the original with the result using a convenient split screen.
How it works
Squoosh uses WebAssembly technology to perform resource-intensive image encoding and decoding operations directly in the browser. This achieves performance close to native applications without requiring additional software installation.
Key idea
The project solves a typical problem for web developers and designers: how to reduce image size without significant quality loss, without spending time uploading files to third-party services and without risking data privacy.

Who is Squoosh suitable for?
Web developers
Squoosh helps developers optimize images for websites: reduce file size, speed up page loading, and improve Core Web Vitals scores. The ability to experiment with compression settings and see results immediately makes the tool indispensable when preparing web graphics.
Designers
Designers can quickly compress mockups, previews, and illustrations before sending them to clients or publishing them in portfolios. Visual comparison between the original and compressed versions helps maintain quality at every stage.
SMM specialists and regular users
SMM specialists can prepare content for social media by reducing image size without losing detail. Regular users will also find the tool useful — for example, to free up disk space in a family photo archive.
How to use Squoosh?
Quick start
- Open the tool in any modern browser.
- Upload an image: drag and drop the file into the browser window or paste it from the clipboard.
- Choose a format and adjust the compression level — manually or via automatic mode.
- Compare the result with the original using the built-in slider.
- Download the processed file.
Working offline
Once the Squoosh page has loaded, the tool continues to work even without an internet connection. This is convenient while traveling or with an unstable connection — just open the site once, and you can use it without restrictions.
Key Squoosh Features
Local processing without server uploads
All operations are performed on the user's device. Files are not transmitted to Google servers or third parties, guaranteeing complete confidentiality of processed images.
Manual and automatic compression settings
Users can independently adjust compression level, quality, palette, and progressive rendering. For those who don't want to dive into details, there is an automatic mode that selects optimal parameters.
Interactive comparison with the original
The slider allows switching between the original and compressed image in real time. This makes it easy to assess quality loss and make an informed decision.
Support for modern formats
Squoosh works with JPEG, PNG, WebP, AVIF, and MozJPEG. Converting to more modern formats (e.g., WebP or AVIF) provides additional file size savings without visible image degradation.
Squoosh Advantages
Complete privacy
Data is processed locally, so images never leave the user's device. This is especially important when working with confidential materials.
Instant operation
No need to wait for files to upload to a server and back — compression happens immediately after loading the image into the browser. This saves time when processing many files.
Clear interface without registration
The tool requires no account creation and imposes no limits on the number of files processed. The interface is intuitive even without instructions.
Squoosh Drawbacks
The tool lacks built-in batch processing capabilities — each image must be processed individually. Additionally, Squoosh is focused exclusively on compression and format conversion; more complex editing (cropping, color correction, retouching) requires other programs. The interface language is not explicitly stated, but the visual design makes it accessible to users of all skill levels.
What tasks does Squoosh solve?
- Compressing images for the web with minimal quality loss. The tool helps find a balance between file size and image clarity.
- Speeding up web page loading. Reduced images load faster in the browser, improving user experience and affecting search engine rankings.
- Preparing content for social media. Squoosh helps reduce the size of photos and illustrations for publication without losing detail.
- Freeing up disk space. Compressing large photo archives can save gigabytes with only a slight reduction in quality.
Squoosh Pricing
Squoosh is completely free. The tool requires no payment, subscriptions, or in-app purchases. There are no limits on the number of processed files.
Squoosh Terms of Use
No registration is required to use the tool. There are no limits on the number of images uploaded or downloaded. Since files are not sent to a server, the terms of use come down to the proper functioning of the user's browser. The tool can be used for any purpose without prior approval.
Squoosh Availability
Squoosh is available in any modern browser. After the initial page load, the tool works fully offline, which is especially valuable with unstable internet connections. The interface language is not explicitly stated, but navigation is intuitive thanks to visual cues and minimalist design.
How Squoosh differs from alternatives
The main difference between Squoosh and other image compression utilities is local processing without data transfer to a server. Many alternatives require uploading files to the cloud, which creates privacy risks and adds processing delays.
Squoosh also wins through the absence of registration, limits, and cost. Unlike tools such as Socrat.ai, VIBE, Delulu Stream, or MagicSlides App, Squoosh does not offer additional features (recognition, content generation, video or presentation work), but perfectly fulfills its single purpose — fast and private image compression.
Conclusion
Squoosh is a fast, private, and free tool from Google for compressing images directly in the browser. It is ideal for web developers, designers, and anyone who needs to reduce file size without losing quality. Thanks to local processing, support for modern formats, and clear result comparison, Squoosh remains one of the best solutions in its niche, requiring no registration, installation, or financial investment.
