Squoosh Alternative: Browser-Based Image Optimization

Squoosh Alternative: ImgBolt Goes Beyond Compression

Looking for a Squoosh alternative? Google's Squoosh is an excellent image optimizer, but it processes only one image at a time and only handles compression — no resizing, conversion, or AI tools. ImgBolt builds on the same browser-based philosophy while adding format conversion, resizing, and AI-powered image processing.

Squoosh vs ImgBolt: Side-by-Side

Where ImgBolt Wins

While Squoosh excels at one thing — compression — ImgBolt covers a much wider range of image processing needs in a single tool.

• More tools in one place — compress, resize, crop, blur, convert, plus five AI-powered tools. Squoosh only handles compression and basic resizing.
• HEIC support — open and convert iPhone photos directly. Squoosh cannot read HEIC files, which is a pain if you work with photos taken on modern iPhones.
• Dedicated format conversion — 30+ converter pages for specific format pairs like HEIC to JPG, PNG to WebP, and JPG to AVIF. Squoosh can convert via re-encoding, but ImgBolt makes it explicit and easy to find.
• AI-powered features — upscale images 2x–4x, remove backgrounds, vectorize logos, and colorize old photos. These capabilities do not exist in Squoosh.
• Target file size resizing — resize to exact KB targets for form submissions, visa applications, and job portals. Squoosh has no equivalent feature.

Where Squoosh Wins

Squoosh is a Google Chrome Labs project built by some of the best web engineers in the world, and it shows in several areas.

• Real-time side-by-side preview — Squoosh's split-view comparison is best-in-class for judging quality loss. You can drag a slider across the image to see exactly what compression does to every pixel.
• Advanced codec options — Squoosh exposes low-level encoder settings like effort level, subsampling, color space, and progressive encoding. ImgBolt abstracts these behind a simpler quality slider.
• More codec choices — MozJPEG, OxiPNG, WebP v2, and multiple AVIF encoder configurations give power users fine-grained control over the exact compression algorithm and parameters.
• Open source — Squoosh's code is publicly available on GitHub. You can inspect the code, contribute, or self-host it.
• Offline support — Squoosh works as a progressive web app with service worker caching. Once loaded, it works without an internet connection.

Who Should Use Which?

The best tool depends on what you are trying to accomplish. Here is a clear guide for each scenario.

• Use ImgBolt if: you need more than just compression. If your workflow involves resizing, cropping, format conversion, or AI tools like background removal and upscaling, ImgBolt handles all of it in one place. It is also the better choice if you work with HEIC files from iPhones.
• Use Squoosh if: you want granular codec-level control and real-time visual quality comparison. If you are a developer fine-tuning compression settings for a specific build pipeline, Squoosh's detailed encoder options are hard to match.
• Use both: use Squoosh for fine-tuning compression settings on critical hero images where every byte and pixel matters, and use ImgBolt for everything else — conversion, resizing, batch format changes, and AI processing.

Beyond Compression: What ImgBolt Offers

ImgBolt is designed as a complete image processing toolkit, not just a compressor. Here is everything you can do beyond what Squoosh offers.

• Convert images between 30+ format pairs — including HEIC, JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and ICO. Dedicated pages for every conversion make it easy to find exactly what you need.
• Resize to exact dimensions or target file sizes — preset modes for passport photos, social media, and common web dimensions. Target a specific file size in KB for form uploads.
• Remove backgrounds with AI — isolate subjects from photos for product listings, headshots, and design work.
• AI upscale images 2x–4x — enhance resolution on low-quality images without losing sharpness or introducing artifacts.
• Vectorize logos and icons to SVG — convert raster images into clean, scalable vector graphics for logos, icons, and illustrations.
• Colorize black and white photos — bring old photographs to life with AI-powered colorization that produces natural, realistic results.

If Squoosh handles your needs perfectly, it is a great tool — there is no reason to switch. But if you find yourself opening multiple tabs for different image tasks, ImgBolt consolidates everything into one place. Try ImgBolt's compressor and see how it compares.
