Questions
Which format compresses best?
WebP is usually the smallest. Use JPG for photos that must open everywhere, and keep PNG only when you need lossless quality.
Will I lose quality?
At 80 to 90 quality the difference is very hard to see, while the file is often 50 to 80 percent smaller.
Are my images uploaded?
No. The conversion runs inside your browser, so your file never leaves your device and nothing is stored on our servers.
Is it free?
Yes. It is free with no sign-up, no watermark and no daily limit.
