Frequently asked questions
Is SammaPix really free?+
Yes. Image compression on SammaPix is 100% free with no limits on file count or size. The Pro plan adds batch ZIP downloads, higher batch limits, and AI-powered features, but standard compression is free forever.
Do my images get uploaded to a server?+
No. SammaPix compresses images entirely inside your browser using JavaScript. Your files never leave your device — nothing is uploaded, stored, or tracked. Your privacy is fully protected.
What image formats are supported?+
SammaPix supports all major image formats: JPEG/JPG, PNG, WebP, GIF, BMP, TIFF, AVIF, and HEIC. You can compress any of these formats directly in your browser.
How much can I compress without losing quality?+
At the default 80% quality setting, most images shrink by 50–80% with no visible quality loss. Photos with lots of detail can often be compressed by 60–90%. The quality slider lets you find the perfect balance for your needs.
What's the difference between Free and Pro?+
Free gives you unlimited compression with single-file downloads. Pro ($7/month) adds batch processing up to 500 images, one-click ZIP downloads, AI-powered file renaming, and zero ads. Both plans process everything in your browser — no uploads.
Why compress images online?
Smaller images load faster and rank better on Google. SammaPix compresses your images directly in your browser using advanced algorithms that analyze each image and remove unnecessary data. You control the quality with a simple slider — most images at the default 80% setting show zero visible difference from the original while shrinking by 50–80%.
Because everything stays on your device, there's zero privacy risk — your photos never touch a server. You won't hit upload limits, and you'll get results instantly.
