Image Compressor
① Design / Assets
What it is: Make image files smaller with barely any visible loss, so pages load faster.
When to use: When large images slow your site, or you need to meet an upload size limit.
Everything runs locally in your browser — nothing is uploaded.
FAQ
Are images uploaded to a server?
No. Compression runs entirely in your browser via Canvas, so images never leave your device — great for sensitive images.
Why does PNG compress worse than JPG?
JPG/WebP are lossy and can shrink files dramatically; PNG is lossless and better suited to icons and transparent images. For photos, convert to JPG or WebP for better compression.
