Step-by-step instructions
- 1
Convert with Preview (macOS Monterey+)
Open the WebP file in Preview (double-click, or right-click → Open With → Preview). Go to File → Export. Set Format to JPEG. Adjust the Quality slider (85–90% recommended). Choose a location and click Save. On macOS Ventura and Sonoma, Preview handles WebP natively at full quality.

Convert with sips (macOS Ventura+)
Open Terminal. Single file: `sips -s format jpeg input.webp --out output.jpg`. Batch convert a folder: `for f in *.webp; do sips -s format jpeg "$f" --out "${f%.webp}.jpg"; done`. sips WebP support was added in macOS 13 Ventura. On older macOS, use FFmpeg instead.

Convert with FFmpeg (older macOS or batch)
Install FFmpeg via Homebrew: `brew install ffmpeg`. Single file: `ffmpeg -i input.webp output.jpg`. Control quality: `ffmpeg -i input.webp -q:v 2 output.jpg` (1=best, 31=worst; 2–5 is high quality). Batch: `for f in *.webp; do ffmpeg -i "$f" "${f%.webp}.jpg"; done`.

Verify the output
Open the JPG in Preview to confirm quality. WebP transparency (if any) appears as white in the JPG. Check file sizes — JPG may be larger than WebP for photographs since WebP has better compression. If size is critical, compare WebP vs JPG visually at the same quality setting.
Why convert WebP to JPG?
WebP is the modern web format, but older apps, email clients, and image editors don't support it. Converting WebP to JPG gives you a universally compatible image for any workflow.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
