What CozyPix does
Compress
Cut image file size by 40–80% with an adjustable quality slider. See the before/after size of each file.
Convert
Convert between JPG, PNG and WebP. WebP is ideal for websites and online shops.
Resize
Set a maximum width or height; aspect ratio is kept. Great for product photos and blog images.
Private by design
All processing happens locally in your browser. Location (EXIF/GPS) data is removed from exported images.
Who it's for: online sellers preparing product photos, bloggers and web developers speeding up their pages, and anyone who needs to email or upload photos under a size limit.
