Frequently asked questions
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the HTML canvas. Your images never leave your device, which makes this safe for private photos.
Which formats can I compress to?
JPEG and WebP, both of which support quality-based compression. WebP usually produces smaller files at the same quality.
Why did my PNG get bigger as JPEG?
Photos compress well as JPEG/WebP, but simple graphics or screenshots with few colors can sometimes be smaller as PNG. Try both and compare the sizes shown.
