SammaPix vs Optimizilla
Optimizilla has been a reliable free image compressor for years. But it uploads your files to a server, caps you at 20 images per session, and offers no WebP conversion or AI features. SammaPix is the modern alternative- built entirely in-browser.
Choose SammaPix if you…
- Care about privacy (files processed 100% in-browser)
- Want WebP conversion alongside compression
- Need AI-generated filenames and alt text for SEO
- Want EXIF metadata stripped from output files
Choose Optimizilla if you…
- Prefer a familiar, established tool you've used for years
- Only need basic JPEG and PNG compression with a slider

The key differences
Privacy - Optimizilla uploads every image to its servers
Optimizilla's compression algorithm runs server-side, which means every image you compress is transmitted to and temporarily stored on their servers. For personal photos, client work, or any sensitive image content, this is a meaningful privacy risk. SammaPix compresses everything using WebAssembly and the Canvas API directly inside your browser. Nothing leaves your device.
WebP conversion- a format Optimizilla doesn't support
Optimizilla compresses JPEG and PNG- it does not convert to WebP. WebP is now supported by all modern browsers and produces files 25-34% smaller than JPEG at equivalent quality. SammaPix converts any image to WebP in-browser in a single click, making it the better choice for anyone focused on web performance or improving Core Web Vitals.
AI rename- the feature Optimizilla will never have
After compressing in Optimizilla, your files retain their original names- DSC_0042-min.jpg tells Google nothing about the image content. SammaPix's AI rename uses Google Gemini to analyze the image and suggest a descriptive, SEO-friendly filename like mountain-lake-sunrise-reflection.webp. This directly improves image search ranking and accessibility.
20-image session limit - Optimizilla stops, SammaPix continues
Optimizilla limits each session to 20 images. If you have 60 product photos to optimize, you need to reload the page and repeat the process three times. SammaPix's free plan also processes 20 files at once, but the Pro plan handles up to 500 files per batch. For high-volume workflows, SammaPix scales - Optimizilla does not.
EXIF removal- protect location data Optimizilla leaves intact
Optimizilla compresses images but does not strip EXIF metadata from the output. That metadata can include GPS coordinates precise to a few meters. SammaPix's EXIF Remover strips all sensitive metadata client-side before you download - GPS, device model, timestamps, and more. This is a feature Optimizilla has never offered.
Who should switch from Optimizilla to SammaPix?
Optimizilla is a fine tool for occasional basic compression. SammaPix is the better choice if:
- You regularly compress more than 20 images. SammaPix Pro handles 500 files per batch, and even the free plan resets with each session without friction.
- You work with sensitive or private images. Optimizilla uploads every file. SammaPix never sends anything outside your browser.
- You publish images to a website. WebP conversion, AI rename, and EXIF removal are all part of a complete web image workflow- and SammaPix offers all three.
- You care about Core Web Vitals. Smaller WebP files with descriptive filenames and stripped metadata improve both performance scores and image SEO simultaneously.
