Full Comparison (2025)
Quick Verdict
Squoosh is a powerful single-image codec lab — great for developers who want pixel-perfect quality tuning on one file. Glopix wins on workflow: batch processing, social media presets, background removal, and 50+ format support mean you're not processing images one at a time.
Squoosh is built around a single image at a time — load, tweak codecs, compare, export. It's a quality tuning tool. Glopix is built around workflows — process 200 images, resize them for six social platforms, remove backgrounds from a product batch, and download a ZIP. Different tools for different jobs.

Squoosh is built as a single-image tool. You drag one image in, adjust the codec settings, compare the before/after, then export. There's no way to process 50 product photos or resize an entire campaign's worth of images in one session. For any real-world workflow with multiple images, this quickly becomes the bottleneck.
Squoosh's strength is its codec control interface — you can tune AVIF's quantizer, set JPEG-XL effort levels, or compare MozJPEG against the browser's built-in JPEG codec with a draggable divider. If you're a developer choosing the exact compression settings for a single hero image, Squoosh's detail level is unmatched in a browser tool. That's its lane — and it does it well.
Where Glopix wins is everything after that single image. Upload 200 product photos, apply 85% quality compression across all of them, resize each to 1200×1200, strip EXIF metadata, and download a ZIP containing all outputs — without refreshing the page or touching the same image twice. That's a workflow. Squoosh can't do it. Glopix was built for it.
Process your entire image batch now
Free, no signup. Upload unlimited images and download a ZIP in minutes.
No. Squoosh processes one image at a time. If you need to compress, resize, or convert multiple images in a single session, you need a different tool. Glopix supports unlimited batch processing with no file count caps.
Glopix.app is the strongest free Squoosh alternative for batch workflows. It handles unlimited images per batch, supports 50+ formats, and includes social media presets, background removal, watermarking, and more — all without a signup.
Squoosh is better for developers who want fine-grained codec control and side-by-side quality previews for a single image. Glopix is better for developers who need to prepare large batches of assets quickly — resizing, compressing, and converting to multiple formats in one session.
Squoosh has limited HEIC support and it can be unreliable across browsers. Glopix provides consistent HEIC conversion and compression support as a first-class feature.
Yes. Glopix is free with no account or signup required, just like Squoosh. The key difference is that Glopix supports batch processing and dozens of tools beyond compression, while Squoosh focuses on single-image codec comparison.
