Frequently asked questions
Which format should I pick?
JPG for photos and maximum compatibility. PNG for screenshots, logos and anything needing transparency. WebP for the smallest files on the modern web.
What happens to transparency when converting PNG to JPG?
JPG can't store transparency, so transparent areas are filled with white — the standard behaviour everywhere.
Can I convert many images at once?
Yes — select or drop multiple files. Single files download directly; batches arrive as a ZIP.
One format in, another format out
Format mismatches are a daily annoyance: a portal that refuses WebP, a form that only accepts JPG, a design tool that needs a transparent PNG. This converter moves images between JPG, PNG and WebP in a click, and it handles whole batches at once — select or drop a dozen files and get them all back, single files as direct downloads and batches as a ZIP.
Which format should you actually use?
- JPG — best for photographs and the safest choice for compatibility. Every system on earth reads JPG. It's lossy, so it's not ideal for sharp-edged graphics, but for photos it's small and universal.
- PNG — lossless and supports transparency, which makes it right for screenshots, logos, icons and diagrams. Files are larger than JPG for photographic content, so don't use it for camera photos you need to keep small.
- WebP — the modern all-rounder, typically 25–35% smaller than an equivalent JPG or PNG at similar quality, and now supported by every current browser. Great for websites; occasionally still rejected by older upload systems, which is exactly when you'd convert it back to JPG here.
What happens to transparency and quality
Converting a transparent PNG to JPG fills the transparent areas with white, because JPG can't store transparency — that's standard behaviour everywhere and worth remembering before you convert a logo. The quality control lets you trade size against fidelity for JPG and WebP output; 90% is a sensible default that's visually lossless for most images while keeping files lean. PNG is always lossless, so the quality setting doesn't apply to it.
Private and batch-friendly
All conversion runs in your browser, so nothing is uploaded regardless of how many files you process. If you also need the result under a specific size, chain it with the image compressor; if you're heading toward a document, JPG to PDF takes it from here.
