I once uploaded client product photos to a free converter that stamped its logo across every image and held the full resolution hostage behind a paywall, discovered at midnight before a launch. Server-side ‘free’ converters monetize your urgency. In-browser conversion has no server, no queue, no watermark, and your images never leave your machine.
Drop in PNG files to get JPG (smaller, universal, no transparency) or WebP (smaller still, modern browsers), or convert back the other way. The decision tree: photographs and complex images → JPG/WebP for size; logos, icons, and anything needing transparency → stay PNG; web delivery where you control the stack → WebP for the bandwidth savings (typically 25–35% smaller than JPG at equal quality).
Try it now: open the free tool, runs 100% in your browser.
Quality discipline: JPG is lossy, so keep originals and convert copies, every re-save degrades. For web images, resize dimensions before converting (a 4000px source displayed at 800px wastes 90%+ of its bytes regardless of format). And check transparency needs first: converting a transparent PNG to JPG fills transparency with black or white permanently, a mistake you only make once.
Bottom line: convert copies not originals, resize before converting, match format to content.
Your turn: use the tool free here, no signup, nothing leaves your device.
