Fogkits vs Squoosh

Both keep still compression on your device. Here's a plain breakdown by codec depth vs everyday job fit — when you want a specialist encoder UI versus a KB-cap path and the tools around it.

Quick take

Choose Squoosh when you want a codec specialist / open lab (Google Chrome Labs): deep per-codec controls, side-by-side inspection, and the encoders Squoosh exposes live (verify UI for current codecs such as AVIF). Best for one careful encode at a time.
Choose Fogkits when you want everyday local compress with an optional KB target, batch stills, a paired under-100KB guide, a local GIF compressor, and the wider local still toolkit around the job.
Both keep core still-compress pixels on-device — this is not the TinyPNG upload story (see Fogkits vs TinyPNG).
Do not claim either product “always makes smaller files.” Compare workflow fit.
Passport photo and background removal on Fogkits upload for server processing — keep them off this page's primary CTAs.

Feature comparison

Surfaces and codec lists change — verify squoosh.app and Fogkits live pages before you rely on a specific encoder or limit. This table is not a size shootout.

Job / dimension	Fogkits	Squoosh
Processing default (still compress)	Browser-local on /image-compressor — source not uploaded to Fogkits for that tool	Browser-local — Squoosh states images never leave your device for compression
Analytics honesty	See Fogkits Privacy; local compress does not upload the image for processing	GitHub Privacy snapshot: image not sent for compress; Google Analytics may collect visitor + before/after size (+ PWA signals) — verify live
UX shape	Quality + optional target KB + max width + before/after sizes	Codec lab: pick encoders/settings, inspect differences, save
Still formats (marketing)	JPG, PNG, WebP on the live compressor	Best-in-class codecs in-browser — verify live list
Batch	Up to ~20 stills on the live compressor (re-check tool)	Single-image codec workflow (verify live)
Under-100KB path	/guides/compress-image-under-100kb + target size — best-effort	Manual encode power; no Fogkits-style checklist guide
GIF	/gif-compressor — browser-local	Not a chat/email GIF toolkit
Wider toolkit	Crop, resize, convert, IG tools (mostly local)	Focused compress/codec app
Passport / cutout	Separate server products — not heroes here	Not a passport product
Size winner?	Not claimed	Not claimed

Where Squoosh wins

Codec lab depth — tune best-in-class encoders in one UI.
Open-source / Chrome Labs credibility for power users.
Ideal when the job is “pick the right codec for this one asset.”
Clear local-pixels marketing for compression work.

Where Fogkits wins

Target KB + max-width levers for email/form caps.
Paired under-100KB how-to.
Batch local stills on Image Compressor.
Local GIF for chat/email loops (GIF Compressor).
Compress inside a local still toolkit (crop/resize/convert).

Frequently asked questions

Is Fogkits a Squoosh replacement?

Not one-for-one. Squoosh is a browser-local codec lab with deep encoder controls. Fogkits Image Compressor is also browser-local for stills, but oriented to quality / target KB / batch everyday jobs, plus a local GIF tool and a wider toolkit.

Do Fogkits and Squoosh both keep images on my device?

For their core still-compress flows, yes. Fogkits does not upload the source for Image Compressor; Squoosh states compression runs locally. Squoosh’s GitHub Privacy notes Google Analytics may still collect visitor and size metrics — verify live. Fogkits passport and background removal do upload — they are not this page’s primary CTAs. See Fogkits Privacy.

Which is better if I need the smallest file?

No honest universal winner. Results depend on source, format, and settings. Pick by privacy workflow and controls — this page does not publish a benchmark table.

Which is better for compressing under 100KB?

Start with Fogkits’ under-100KB guide and Image Compressor for an on-device KB-cap pass. Squoosh can also produce small files with the right settings. Neither guarantees a third-party form will accept every file.

Does Squoosh support batch compress?

Squoosh’s public shape is a single-image codec workflow (verify live). Fogkits Image Compressor lets you add multiple stills and apply one recipe (live soft cap around 20 — re-check the tool).

Does Squoosh replace Fogkits GIF Compressor?

No. For classic GIF chat/email loops, use Fogkits GIF Compressor. Squoosh focuses on still codecs. See Fogkits vs Ezgif for animation-suite depth.
