AllTools vs Squoosh — Free Browser-Based Image Compression

Squoosh vs AllTools: One Great Compressor or 40+ Image Tools?

Squoosh is a browser-based image compression tool built by the Google Chrome team. It earned its reputation through a clean, focused interface and serious codec support. You drop an image in, pick a codec like MozJPEG, OxiPNG, WebP, AVIF, or even JPEG XL, and adjust settings while watching a side-by-side preview with pixel-level comparison. It is genuinely one of the best single-image compression tools ever made, and it is completely open source.

AllTools takes a broader approach. The Image Compressor handles compression with JPEG, PNG, WebP, and AVIF support, but it sits alongside 40+ other image tools — resize, crop, format conversion, background removal, EXIF management, watermarking, and filters. Beyond images, AllTools provides 562 tools across 22 categories, all running client-side in your browser.

Both tools share the same philosophy: process images in the browser, never upload to a server. The difference is scope. Squoosh does one thing with exceptional depth. AllTools covers the full image workflow and then some.

Quick Summary

Choose Squoosh if: You want the best possible control over a single image’s compression. Squoosh’s codec selection, side-by-side pixel-level preview, and advanced encoder options (MozJPEG, OxiPNG, JPEG XL) are unmatched. If your workflow is compressing one image at a time with maximum precision, Squoosh is purpose-built for that.

Choose AllTools if: You need more than compression. If your workflow involves compressing, then resizing, then converting formats, then stripping EXIF data, then cropping for a social media preset, AllTools handles the entire chain. You also get 520+ tools in other categories for everything else.

The short version: Squoosh is a specialist scalpel. AllTools is a complete workshop.

Feature Comparison

Where Squoosh Wins

Codec depth and encoder options

Squoosh’s codec support is genuinely best-in-class among browser tools. It gives you access to MozJPEG (Mozilla’s optimized JPEG encoder), OxiPNG (Rust-based PNG optimizer), WebP, AVIF, JPEG XL, and experimental codecs like WebP2. Each codec exposes its full set of encoder parameters. With MozJPEG, you can adjust quality, smoothing, and progressive scan. With OxiPNG, you can set optimization level and interlacing. With AVIF, you can control speed, minimum and maximum quantizer values, and tiling.

This level of control matters for developers and designers who need to squeeze out every last byte. If you are optimizing hero images for a high-traffic website and the difference between quality 75 and quality 78 matters to your visual standards, Squoosh gives you the knobs to find that exact sweet spot.

AllTools provides a quality slider for its supported formats, which covers most use cases well. But it does not expose the low-level encoder parameters that Squoosh offers.

Side-by-side pixel-level comparison

Squoosh’s comparison view is its signature feature. You see the original and compressed versions side by side with a draggable divider. You can zoom in to the pixel level to inspect compression artifacts. The file size difference is displayed in real time as you adjust settings. This instant visual feedback loop makes it easy to find the optimal quality-to-size ratio for any specific image.

AllTools has a before/after comparison slider, but Squoosh’s implementation with pixel-level zoom and real-time codec switching is more refined for this specific task.

CLI for build pipelines

Squoosh provides squoosh-cli, a command-line tool that brings the same codec support to automated workflows. You can integrate it into CI/CD pipelines, build scripts, or batch processing workflows. For developers who need to compress hundreds of images during deployment, squoosh-cli is a practical option. AllTools is an interactive browser tool without a CLI equivalent.

Open source and inspectable

Squoosh is open source under the Apache 2.0 license. You can inspect the code, fork it, modify it, or self-host it. For organizations with strict software procurement policies, the ability to audit and host the tool internally is valuable. AllTools is a hosted service.

Where AllTools Wins

A complete image workflow, not just compression

Compression is usually one step in a multi-step workflow. A typical image preparation workflow might look like this: resize the image to the right dimensions, crop to the correct aspect ratio, strip EXIF data for privacy, compress for web delivery, and convert to a modern format. With Squoosh, you can compress and optionally resize. For everything else, you need a different tool.

AllTools provides dedicated tools for every step. The Image Resizer handles exact dimensions and social media presets. The Image Cropper offers aspect ratio presets and freeform cropping. The Image EXIF Remover strips GPS coordinates, camera model, and other metadata you might not want published. The Background Remover creates transparent backgrounds for product photos and profile pictures. Each tool is purpose-built with a focused interface.

Standalone format converters

Squoosh handles format conversion as a side effect of compression: select a different output codec, and you have effectively converted the image. This works, but it means you always go through the compression interface even when you just want a format change.

AllTools provides 12+ standalone format converters, each optimized for its specific conversion. JPG to WebP for modern web delivery. PNG to JPG for reducing oversized screenshots. HEIC to JPG for converting iPhone photos to a universally compatible format. WebP to PNG for when you need broad compatibility. Each converter has its own page, its own settings, and its own optimizations for that specific conversion path.

EXIF and metadata management

When you share photos online, the EXIF data embedded in those files can reveal your GPS location, the device you used, timestamps, and even your name. Squoosh does not include any EXIF management features. AllTools has a dedicated Image EXIF Remover that lets you inspect and selectively strip metadata before sharing. For journalists, activists, or anyone posting photos where location privacy matters, this is not a minor feature.

520+ tools beyond images

After compressing an image, your next task might be completely unrelated. You might need to merge two PDFs, format a block of JSON, generate a strong password, or calculate a loan payment. Squoosh sends you elsewhere for all of that.

AllTools covers 22 categories and 562 tools. The PDF tools handle merging, splitting, and compressing documents. The Developer tools include JSON formatters, regex testers, and Base64 encoders. The Security tools provide password generators and encryption utilities. Everything runs in the browser with the same privacy guarantee.

No single-image limitation

Squoosh processes one image at a time. There is no batch mode, no queue, and no way to apply the same settings to multiple files. If you have 15 product photos to compress, you process them one by one.

AllTools supports processing multiple images through its interface, and you can open multiple browser tabs for parallel processing. There is no per-session or monthly limit.

The Bottom Line

Use Squoosh when:

• You are compressing a single image and want pixel-perfect control over the output
• You need access to specialized codecs like MozJPEG, OxiPNG, or JPEG XL
• You want to visually compare codecs side by side at the pixel level
• You need a CLI tool for build pipeline integration
• You value open source and want to inspect or self-host the tool

Use AllTools when:

• Your image workflow involves more than compression (resize, crop, convert, EXIF removal, background removal)
• You regularly process multiple images and want to move through them quickly
• You need format-specific converters like HEIC to JPG or JPG to WebP
• You need tools beyond images (PDF, developer, security, math, business)
• You want one platform for your entire browser-based toolkit

The practical recommendation

If image compression is your entire need and you want the deepest possible control, Squoosh is hard to beat. The codec options, the pixel-level preview, and the CLI make it the gold standard for single-image compression optimization.

If compression is part of a larger workflow, AllTools is the more practical choice. You compress the image, then resize it, then strip the EXIF data, then convert the format, and then move on to an entirely different task — all without leaving the site. Both tools are free and both keep your images private. The choice comes down to depth versus breadth.

FAQ

Does AllTools use the same codecs as Squoosh?

AllTools uses the browser’s built-in Canvas API and encoding capabilities for JPEG, PNG, WebP, and AVIF compression. Squoosh uses WebAssembly-compiled versions of specialized codecs like MozJPEG and OxiPNG, which can produce slightly smaller files at the same visual quality. For most practical purposes, the difference is small, but Squoosh has a technical edge in codec quality for JPEG and PNG.

Can Squoosh batch process images?

No. Squoosh processes one image at a time, both in the web interface and the CLI (though the CLI can be scripted to loop through files). AllTools also processes images individually through the interface, but you can open multiple tabs for parallel processing. Neither tool offers a true batch upload with bulk processing in a single step.

Is Squoosh still maintained?

Squoosh was created by the Google Chrome team and is hosted on GitHub as an open-source project. Development has slowed compared to its early years, but the tool remains functional and available at squoosh.app. Because it runs in the browser, it continues to work regardless of active development. AllTools is actively developed with new tools and improvements added regularly.

Which tool produces smaller files?

For JPEG compression, Squoosh with MozJPEG generally produces files 5-10% smaller than standard JPEG encoding at the same visual quality. For PNG, Squoosh’s OxiPNG optimizer is more aggressive than standard browser PNG encoding. For WebP and AVIF, the differences are smaller since both tools use the browser’s built-in encoding. If absolute minimum file size is critical, Squoosh’s specialized codecs have an edge.

Should I use AVIF or WebP for my website?

Both are excellent modern formats. AVIF typically produces files 20-30% smaller than WebP at the same quality, making it the better choice for maximum compression. However, WebP has broader browser support (98%+ vs 93%+ for AVIF). The practical approach is to use AVIF as the primary format with WebP as a fallback. Both AllTools and Squoosh support both formats, so you can compress to each and compare the results for your specific images.
