Meet a 200 KB size limit
200 KB is a common, relatively relaxed limit — it shows up on forum and community site avatar uploads, some professional networking profile photos, content management systems with upload caps, and email or messaging tools that flag larger attachments for slow connections.
This page opens Downscale Image with the file-size target pre-set to 200 KB, so there's no configuration to do — just upload your photo and the tool finds a quality and resolution combination that fits.
At 200 KB, the vast majority of photos compress down while keeping their original resolution and looking essentially unchanged to the eye. Only very large, highly detailed originals — think high-resolution landscape or texture-heavy photography — are likely to need any noticeable reduction to fit under this limit.
As always, compression happens locally on your device. Nothing about your photo is sent to a server in the process.
