Image converter: WebP, PNG, JPG and SVG
TL;DR: drop up to 50 images, pick PNG, JPG or WebP and download the results one by one or as a ZIP. Conversion runs in your browser, so your files are never uploaded.

Most image tasks on a website come down to the same few conversions: WebP from the web to PNG or JPG for editing and sharing, PNG and JPG to WebP to make pages lighter, and SVG icons to PNG for places that do not accept vectors. This converter does all of them in one place, for a batch of files at once.
How to use the converter
- Add images. Drag up to 50 files onto the box, choose them with the button or paste a copied image with Ctrl+V.
- Check the output format. It is already set for this page; you can switch between PNG, JPG and WebP at any time.
- Adjust the settings. For JPG and WebP set the quality (85 is a good default). For JPG pick the colour that fills transparent areas.
- Download. Save files one by one or all together as a ZIP. Each row shows the size before and after.
Which format to choose
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| WebP | Lossy or lossless | Yes | Photos and graphics on websites |
| PNG | Lossless | Yes | Screenshots, logos, images you will edit again |
| JPG | Lossy | No | Photos for email, documents, older software |
| SVG | Vector (text) | Yes | Icons and logos at any size |
For a website, WebP is usually the right choice: according to Google, lossless WebP files are about 26% smaller than PNG, and lossy WebP is 25–34% smaller than JPG at the same visual quality. Keep PNG for screenshots and images you will edit again, and JPG for places that do not open WebP, such as some email clients and older office software.
At YuSMP Group we build websites and keep them fast, and images and PDFs are the most common reason pages load slowly. If you need to move a whole site to lighter formats rather than a few files, see our web development service or start with the page speed test.
FAQ
Are my images uploaded to a server?
No. The page reads files in your browser and converts them in a Web Worker on your device. Nothing is sent over the network, so the converter is safe for private photos and client work.
Which formats can I convert?
You can add WebP, PNG, JPG, GIF, BMP, AVIF and SVG files and convert them to PNG, JPG or WebP. Animated GIF and WebP files are converted as a single image from the first frame.
How many files can I convert at once?
Up to 50 files at a time, each up to 100 MB. They are processed in parallel in the background, so the page stays responsive while you wait.
Is transparency kept?
Yes, when you convert to PNG or WebP. JPG has no transparency, so transparent areas are filled with the background colour you choose: white, black or any other.
Why did the file get bigger?
PNG is lossless and stores every pixel exactly, so a PNG made from a WebP or JPG is often larger than the original. Choose WebP or JPG if you need a smaller file.
Is EXIF data removed?
Yes. Conversion redraws the image, so camera details and GPS location from EXIF are not copied to the new file. Colours are saved in the standard sRGB space.
Does it work on a phone?
Yes, in current Safari on iPhone and iPad and in Chrome on Android. Very large photos may exceed the canvas size limit of mobile Safari (about 16.7 megapixels) and show an error.
