Lower quality first
Quality around 60% is often enough for forms and profile photos.
Under 100KB
Compress an image under 100KB.
Use lower quality, smaller width, and WebP output to target strict upload limits. Start around 60% quality and 1000px width, then adjust if needed.
How to reach 100KB
Reduce dimensions
A smaller width reduces file size while keeping the image usable.
Use WebP
WebP usually creates smaller web-ready images than JPG or PNG.
