How to get the best results
Images
Use WebP for the smallest files. 70-80% quality keeps crisp edges for screenshots; 60-70% works for photos. Select Maximum reduction when sending proofs.
Videos
Balanced + 50-70% target fits most uploads. Use Quality-first for footage that must stay sharp, Size-first for quick shares or receipts.
FAQ
Do my files leave the browser?
No. Compression happens entirely client-side with Canvas and MediaRecorder APIs. Your uploads never touch our servers.
Can I download multiple times?
Yes. Rerun compression with new settings as often as you like. The page remembers your last configuration for convenience.
Does this work on mobile?
The layout stays responsive on phones and tablets. Heavier videos may take longer on slower devices, so keep the tab open while it finishes.
