How to convert images
- Add your images. Drag and drop or click to browse — any format your browser can open (JPEG, PNG, WebP, GIF, BMP). They appear in a list; nothing is processed until you say so.
- Pick the target format — JPEG, PNG or WebP — and a quality level (JPEG/WebP; default 90 is near-indistinguishable from the source).
- Click Convert images. A progress line tracks the batch; results appear with old and new sizes.
- Download each file individually, or grab the whole batch with Download all.
Which format should you choose?
- JPEG — the universal default. Every device, browser, printer and upload portal accepts it. Best for photographs; it has no transparency, so transparent areas are flattened onto white.
- PNG — lossless storage with full transparency. The right target for screenshots, logos, line art, text-heavy images, and anything you'll keep editing. For photographs it produces big files (use our compressor if you need small PNGs).
- WebP — Google's modern format: 25–35% smaller than JPEG at the same visual quality, with transparency support. Ideal for websites; supported by all current browsers. Some older office software still won't open it — convert those submissions to JPEG.
What conversion does to quality
Converting between lossy formats (JPEG ↔ WebP) re-encodes the image at the quality you choose — at 90+ the difference is essentially invisible, but every lossy re-encode discards a little data, so don't bounce images back and forth repeatedly. Converting to PNG is lossless from that point on: the file preserves exactly what came in — but it cannot recover detail a previous JPEG already discarded, which is why JPEG→PNG makes files bigger without making them sharper. Converting a transparent PNG to JPEG flattens transparency onto white; choose WebP or PNG when transparency must survive.
Common reasons to convert
- Upload portals that only accept JPEG (job applications, government forms, marketplaces).
- Websites that want WebP for speed, or PNG for crisp UI graphics.
- Old software that can't open WebP or HEIC exports.
- Printing services that demand JPEG or PNG at full resolution.
- Archiving edits in lossless PNG before exporting JPEG copies for sharing.
Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens entirely in your browser. Your images never leave your device, and closing the tab discards everything.
Is converting JPEG to PNG lossless?
The PNG itself is stored losslessly, but converting cannot bring back detail the JPEG already threw away. Expect a larger file with exactly the same visible quality — useful when a system demands PNG, not as a way to restore an image.
Which format should I convert to?
JPEG for photographs that must work everywhere; WebP for the best compression on the modern web (25–35% smaller than JPEG at equal quality); PNG for screenshots, logos, line art and anything with transparency.
What happens to transparency when converting to JPEG?
JPEG has no alpha channel, so transparent areas are flattened onto a white background. If you need transparency, convert to PNG or WebP instead.
Can I convert many images at once?
Yes. Add as many images as you like to the queue, choose one output format, and convert the whole batch. Download files individually or all at once.
Does it work on my phone?
Yes. The converter works in any modern mobile browser — pick photos straight from your camera roll.
