How image compression works
For photos, a small drop in quality removes a lot of file size that the eye barely notices. Lowering the maximum width helps even more, because a 4000 px photo is far larger than most websites and emails need. A quality of 70-80% is a good starting point.
Which format should I choose?
JPEG works everywhere. WebP is usually smaller at the same quality and is supported by all modern browsers. Transparent areas of PNG files are filled with white in the output.
Frequently asked questions
Are my images uploaded?
No. Compression happens in your browser, so your files stay on your device.
Can I compress PNG files?
Yes. PNG files can be loaded and saved as smaller JPEG or WebP images. Transparency is replaced by a white background.
What quality should I use?
Start at 75%. If the image looks fine, try lower. If you see blur or blocks, go higher.
