Why compress images?
Large images slow down websites, use more mobile data, and often get rejected by email or form uploads. Compressing first keeps the picture looking good while making it far easier to send, post and load.
Frequently asked questions
Will compression ruin my photo?
At 80–90% quality, most photos look unchanged. Go lower only when file size matters more than fine detail.
Is my image uploaded?
No. Compression runs on your device, in your browser.
