Free TinyPNG Alternative — No Upload, Unlimited
Free TinyPNG alternative that compresses images without uploading to servers. No 500-image monthly limit, no API key needed. Full quality control.
TinyPNG is a popular image compression service — but it uploads your images to remote servers, limits free users to 500 images per month, and restricts file sizes to 5MB. Our alternative compresses images locally in your browser with no uploads, no monthly limits, and full control over the quality slider.

How It Works
This compressor uses your browser's native Canvas API and intelligent quality reduction algorithms to minimize image file size while preserving visual quality. Drop your images, adjust the quality slider, and see the compressed result with a side-by-side comparison.
The tool re-encodes images at your chosen quality level, stripping unnecessary metadata (EXIF, ICC profiles) and optimizing the encoding. You see the exact file size savings and visual difference before downloading.
