Standard monthly is USD 21.95/month promotional (regular USD 24.99/month, 300 credits/month). The yearly promo banner displays only "7.66 USD per month" (3,000 credits/year) without printing the annual invoice total before login, so the annual total is marked unverified.

- Original historical observation
CompressNow is a fast, 100% client-side compressor: your image never leaves your browser, and in 0.9s it shrinks our 4.24 MB benchmark PNG to 579.8 KB (-85.99%, 7.14×) at 42.34 dB PSNR (02_workspace.png). Note that it only outputs JPG or WebP (disclosed upfront), so users with transparent PNGs should select the WebP toggle.
