Free limits: 3/day server, unlimited browser. Native PNG/JPG/WebP/GIF/BMP convert locally. TIFF, AVIF, HEIC, SVG need server libraries.
Quality: High is 0.92 JPEG, Medium 0.80. PNG is lossless. WebP balances both for web.
Transparency: PNG and WebP preserve alpha. JPG flattens on black canvas base — convert logos to PNG, not JPG.
Privacy: Browser path never uploads. Server path is quota-guarded and transient.
Limits: Single file, same dimensions, no resize or compress controls here. Pair with Compressor and Resizer after.

GIF frame extraction: Designers pull PNG stills from GIFs for thumbnails and storyboards. Miami social managers repurpose $2,000 shoot GIFs into feed stills.
Legacy CMS survival: Old systems rejecting WebP need JPG fallbacks generated in bulk before migrations. Seattle teams planning $1M replatforms convert libraries ahead of launch freezes.
