Frequently asked questions
Are my images uploaded to a server?
No. Compression happens in your browser using the Canvas API, so your photos never leave your device.
Which format gives the smallest file?
WebP is usually 25–35% smaller than JPG at the same visual quality and is supported by all modern browsers. Use JPG for maximum compatibility.
What quality setting should I use?
For photos on websites, 70–80% quality is a good balance — the difference is hard to see but the file is often 60–80% smaller.
Why did my PNG get bigger?
PNG is lossless, so the quality slider does not apply to it. Convert to WebP or JPG to reduce the size of photos.
