Rather than asking you to guess a quality number, this tool picks one for you. It saves the image at several settings and keeps the lowest quality that still looks close to the original.
The three strengths are simply different judgements of that balance. "Gentle" keeps the picture looking its best and saves less; "Strong" produces the smallest file and accepts a visible drop; "Balanced" sits between them and suits most photographs.
The saving reported is measured from the real output file, not estimated, so what you see is what you will download.

Questions
How is this different from the JPG Compressor?
The JPG Compressor gives you the quality slider and lets you decide. This one decides for you. Use this when you do not want to think about it, and that one when you do.
Can I set a file size target instead?
Yes, with the Custom Image Size Compressor. That one aims at a number in KB; this one aims at a balance of quality and size.
Is this tool free?
Yes. Every tool here is free, and you do not need an account, an email address or a phone number.
Is my file uploaded to your server?
No. This tool runs inside your own browser, so the file never leaves your phone or computer. Once the page has loaded you can even switch off your internet connection and the tool will still work.
Which files can I use?
This tool accepts JPG, PNG and WebP. The largest file it will take is 25 MB.
