- Open the file picker and choose the image you want to convert.
- Pick your output format from the options: JPG, PNG or WebP.
- Download the converted image. It is ready immediately — there is no waiting or processing queue.
The conversion runs entirely in your browser. Your image is never uploaded, so you can convert photos, screenshots and work files freely without worrying about who can see them.
JPG is the standard for photographic images because it keeps small file sizes. PNG is best for graphics, logos and anything that needs a transparent background. WebP is a modern format that combines good compression with transparency support, making it a strong choice for websites.
Format tips
WebP is usually your best option for the web — it gives you excellent compression while supporting transparency, so photos and graphics both stay small. Use JPG for photos that will be shared or used in software that expects a JPG. Use PNG when you need lossless quality or you want to preserve transparency for further editing.
If you convert a PNG with transparency to JPG, remember that JPG has no alpha channel. The transparent area will be flattened, typically to a solid background, so check the result if transparency matters to you. Also keep in mind that converting between lossy formats (for example JPG to WebP) results in a fresh re-encode, so use your highest-quality source image whenever possible.
Why use it
Websites load much faster with WebP images, and email services and image editors often require a specific format before you can continue. Instead of hunting for a desktop app or uploading your files to a third-party service, convert formats instantly in the browser. There is nothing to install, no file size limit, and no risk of your images being stored elsewhere.
Real-world use cases
- Blog and e-commerce: Shrink product photos from 4MB to ~200KB before upload. Your pages load faster and Google PageSpeed scores improve.
- Email and forms: Many inboxes reject >10MB attachments. Compress once and you reliably stay under limits.
- Portfolio and social: Keep visual quality high at 75-85% while cutting bandwidth for viewers on mobile data.
How it compares
| Tool | Upload required | Privacy | Batch | Cost |
|---|---|---|---|---|
| This tool | No | 100% local | 1-by-1 (high quality) | Free |
| TinyPNG/Squoosh | Yes / No | Server or local | Yes | Freemium |
| Photoshop | No | Local | Yes | Paid |
For sensitive images or quick one-offs, a local browser tool wins on privacy and speed. For massive bulk jobs, a desktop app may be faster.
Pro tips
- For photos, try quality 78-82% first. You usually save 60-70% size with no visible loss.
- Scale down dimensions before lowering quality. A 4000px photo at 2000px is 4x smaller even at high quality.
- Keep a backup of the original. You can always re-export at lower quality, but you cannot recover detail after saving over the original.
