Frequently asked questions
Are my images uploaded?
No. Compression happens on your device using your browser's canvas, so the image never leaves it.
Which format is smallest?
WebP is usually smallest at the same visual quality. JPEG is the most widely compatible.
Why did my PNG get bigger?
PNG is lossless, so photographs compress far better as JPEG or WebP. Use those formats for photos.
