How it works
Your image is decoded in the browser, resized on a canvas, and re-encoded to the selected format and quality. No server upload is required.
Tips for best results
- Try WebP for smaller sizes with good quality.
- Reducing scale to 50–80% often yields significant savings.
- PNG is lossless and best for graphics with transparency.
FAQs
Do you upload my images to a server?
No. Processing happens in your browser using a canvas, so your files never leave your device.
Which format should I choose?
Use WebP for photographs (small size with high quality), JPG for wide compatibility, and PNG for graphics with transparency or text.
Why is the quality slider disabled for PNG?
PNG is a lossless format; its encoder does not use a quality setting like JPG or WebP.
