SammaPix vs TinyPNG
Both are free. Both compress images. But only one converts to WebP, renames files with AI, and never uploads your photos to a server.
Choose SammaPix if you…
- Want WebP conversion built-in
- Need AI-generated SEO filenames
- Care about privacy (100% client-side)
- Want a quality slider (not fixed)
Choose TinyPNG if you…
- Use WordPress and need a plugin
- Need API integration for automated pipelines

The key differences
Privacy — your files never leave your device
TinyPNG uploads your images to their servers for compression. SammaPix compresses and converts everything locally in your browser using WebAssembly and the Canvas API. Your files are never sent anywhere — this matters if you work with client photos, confidential screenshots, or private images.
WebP conversion — TinyPNG doesn't do it for free
WebP is 25-34% smaller than JPEG at equivalent quality. It's supported by all modern browsers and improves Core Web Vitals. TinyPNG supports WebP input but doesn't convert JPG/PNG to WebP. SammaPix converts any image to WebP in one click, in-browser, for free.
AI rename — a feature TinyPNG doesn't have at all
SammaPix uses Google Gemini to analyze each image and generate an SEO-optimized filename and alt text. Upload IMG_4829.jpg, get back golden-retriever-puppy-playing-grass.webp — automatically. This feature is free with a login (5/day), or unlimited on Pro.
Price — SammaPix Pro is 3x cheaper
TinyPNG Pro starts at $25/month. SammaPix Pro is $7/month and includes unlimited AI rename (200/day), bulk processing up to 100 files, ZIP download, and no ads. For most users, the free plan is enough forever.
