How to compress JPG
- Drop the JPG.
- Pick a quality.
- Press Compress and download.
What happens to your file
The image is decoded and re-encoded at the quality you chose. JPEG quality is a trade between file size and the blockiness you can see in flat areas and along edges; 82 is where most photographs stop looking different from the original.
Re-encoding a JPEG always costs a little detail. Do it once, from the original, not repeatedly.
Camera metadata is dropped in the re-encode.
Questions
What quality should I use?
82 for anything you will look at closely; 70 for web thumbnails and previews; 55 only when size matters more than the picture.
Why is a lower quality sometimes larger?
It should not be, from the same source. If it is, the original was already encoded by a very efficient encoder; the page shows both sizes so you can keep the original.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
