What the Image Format Converter does
This tool changes a picture from one file type to another: PNG, JPG, or WebP. Drop in a single image, pick the format you want, and download the result. It runs entirely inside your browser using an HTML canvas, so the picture never gets uploaded anywhere.
It is handy when a website only accepts JPG, when you want a smaller WebP for a faster-loading page, or when you need a PNG so a transparent logo stays crisp. Designers, bloggers, store owners, and anyone wrangling screenshots will find it quick.
How to use it
- Drop an image onto the box, or click it to browse and pick a file from your device.
- Check the original size and dimensions shown under the file name.
- Open the “Convert to” dropdown and choose PNG, JPG, or WebP.
- Watch the live preview update, along with the new file size (and a ”% smaller” tag when it shrank).
- Click Download to save the converted image.
That is the whole flow. There are no extra steps, accounts, or watermarks.
Why convert here
Everything happens on your own machine, so private screenshots, client work, and personal photos stay on your device. Conversions are instant because there is no upload or queue, and the tool is free with no sign-up. It works on a phone, tablet, or laptop with any modern browser.
One thing worth knowing: JPG cannot store transparency, so when you convert a transparent PNG to JPG the see-through areas are filled with white. If you need to keep transparency, pick PNG or WebP instead. WebP usually gives the smallest file at similar quality, which is great for web pages.
Quick tip
Need to convert a whole folder of images at once? This page handles a file at a time. For batch jobs across many files, the BulkPro desktop app from the same team (Bilgetek) is built for that.
Frequently asked questions
- What image formats can I convert between?
- You can convert any image you upload into PNG, JPG, or WebP. Pick the target format from the 'Convert to' dropdown and the tool re-encodes your picture in that format.
- What happens to transparency when I convert a PNG to JPG?
- JPG does not support transparency, so any see-through areas are filled with a solid white background during conversion. If you need to keep transparency, choose PNG or WebP as the output instead.
- Are my images uploaded to a server?
- No. The conversion runs locally in your browser on a canvas, so the image stays on your device and is never sent anywhere. That makes it safe for private screenshots and client files.
- Which format gives the smallest file size?
- WebP is usually the smallest at comparable quality, which makes it a good choice for web pages. After converting, the page shows the new file size and a 'percent smaller' tag so you can compare.
