How does it work?

Drop your image: it opens in the editor and the Export window appears, set to JPG. Lower the quality with the slider: between 70 and 85, the difference is rarely visible and the file is much lighter. WebP usually gives an even smaller file at the same quality, and keeps transparency.

To save more, also reduce the dimensions: halving the width divides the number of pixels by four. The real file size is shown below the preview before you download.

Examples

Lightening a photo for an article

A 4000 × 3000 pixel photo (12 MP), exported at 2000 × 1500 as JPG at quality 80: four times fewer pixels and stronger compression, for a file of about 500 KB instead of several megabytes. The exact size depends on the content of the photo.

Sending images by email

Your email service limits attachments to 10 MB and you want to send 8 photos. Aiming for 1 MB at most per photo (1600 pixels wide, JPG quality 75), all 8 photos fit in a single message, with 2 MB to spare.

Frequently asked questions

Can I target an exact file size?
The editor shows the real file size with every setting: adjust the quality or the dimensions until you are under the size you need. Start with the quality (80, then 70), then reduce the dimensions if necessary.
JPG or WebP: which should I choose?
WebP is often 25 to 35% lighter than JPG at the same visual quality and keeps transparency; every modern browser can read it. JPG remains the most compatible format (older software, printing, official forms).
Why isn’t a PNG any lighter?
PNG is a lossless format: it has no quality setting and stays heavy for photos. It suits screenshots, logos and images with transparency. For a photo, choose JPG or WebP.
Are my images uploaded to a server?
No. Images are opened, edited and encoded in your browser, on your device. No image, file name or layer text is uploaded: you can even go offline once the page has loaded. Closing the tab erases your work in progress.
