Fix slow pages and broken iPhone uploads without sending photos to a server

Your storefront looks sharp — but Lighthouse says otherwise

You shot beautiful product photos on iPhone, exported PNGs from design tools, and pasted them straight into Shopify or WordPress. Then PageSpeed screams: oversized images, wrong format, LCP in the red. You are not bad at SEO — your pipeline is.

Cloud image optimizers create new headaches

Bulk upload tools promise one-click fixes, but creators and store owners keep hitting the same walls:

• Product shots and model releases sit on servers outside your control.
• HEIC-to-JPG converters online inject ads or downsample without asking.
• API-based optimizers charge per image once your catalog grows.
• Background removal services train on your uploads unless you read every policy.

Client-side compression that respects your pixels

SnapKit processes images with Canvas and WASM in the browser. Convert HEIC, shrink WebP, strip backgrounds — preview before export, keep EXIF only when you want it.

Convert HEIC and exotic formats locally

The image converter handles PNG, JPG, WebP, and HEIC without a round trip to the cloud.

Compress for speed without mushy edges

Dial quality in the image compressor and watch file size drop while text stays crisp.

Clean catalog shots in one pass

Pair compression with the AI background remover for marketplace-ready assets.

**Your files never leave the browser.** SnapKit runs WebAssembly, FFmpeg, and Canvas directly in your RAM — instant speed, zero cloud uploads, and privacy you can actually trust.
