FAQ
Does my image leave my computer?+
No. Compression happens entirely in your browser using the browser-image-compression library. Nothing is uploaded.
What quality setting should I pick?+
70 to 80% is the sweet spot for most photos. Visually identical to the original, often 70% smaller. Use 90% and up for hero images on a website. Drop to 50 to 60% for maximum compression.
Why is the output sometimes bigger?+
If the input is already heavily compressed (like a Twitter screenshot), the encoder may not be able to do better. The tool tells you when this happens.
