| Pricing transparency | 35 / 35 100% free with no account registration, paywalls, or file-count caps; the landing page and workspace clearly disclose upfront that PNG inputs are converted to WebP for maximum compression (Format: PNG → WebP). Dropping our 4,137.9 KB (2048×2048) anchor PNG immediately enabled a free 276.0 KB download (01_landing.png, 02_workspace.png, 03_download.png). | 32 / 35 Clearly states right below the dropzone: 'Drop up to 50 files here to optimize. Compress JPG, GIF and PNG online. The files should have maximum 10Mb. Login to remove the restriction.' (01_landing.png). |
