Frequently asked questions
Are my images uploaded to a server?
No. The compression runs in your browser using your own device. The file never leaves your computer or phone.
Why did my PNG barely get smaller?
PNG is a lossless format, so there is little to remove. Switch the output format to WebP or JPG to get a much smaller file.
Which quality setting should I use?
Around 70 to 80 percent is a good balance for photos. Go lower for thumbnails and higher when the image has fine detail or text.
Is there a file size limit?
There is no fixed limit. Very large images can be slow on older phones because all the work happens on your device.
