Compress JPEG to 50KB
Compressing a JPEG to 50KB is the sweet spot for email signatures, web thumbnails and lightweight pages — a 800–1000px photo usually fits with acceptable quality. The tool searches for the highest quality that stays under 50KB, entirely on your device.

What fits in 50KB — realistic expectations
At 50KB you can keep a 800–1000px photo looking respectable (roughly 50–65% JPEG quality). That covers email signature images, blog thumbnails, and classified-ad uploads. It's also a common cap for school and government portals.
For camera-resolution images, resize before compressing: a 4000px original squeezed to 50KB will look far worse than the same shot resized to 900px first. The two-step approach (resize, then compress) is the professional workflow.

Frequently asked questions
Can a phone photo fit in 50KB?
Yes, but resize it first. A full-resolution phone photo forced under 50KB looks heavily degraded; resized to ~900px it fits at reasonable quality.
Is 50KB enough for a sharp web image?
For images displayed up to ~1000px wide, yes — expect medium JPEG quality. For hero images or retina displays, budget 100–200KB instead.
Is my image uploaded to compress it?
No. The size search and compression run entirely in your browser — your image never leaves your device.
