Need to change a PNG to JPG, or shrink a heavy JPG into a lighter WEBP? This free online image converter does it in your browser in a few seconds. Add one image or a whole batch, choose a format, and download the results. There is no signup, no watermark, and your photos never leave your device.
How to Convert an Image Online
- Add your images. Drag them into the box above, or click it and choose files from your phone or computer.
- Pick the output format. Choose JPG, PNG or WEBP.
- Adjust quality and size (optional). Use the quality slider for JPG and WEBP, and type a width in pixels if you also want a smaller picture.
- Click Convert. Download each file on its own, or press Download all to get one ZIP file.
Supported Image Formats
You can add JPG, PNG, WEBP, GIF, BMP and SVG files, plus HEIC photos in browsers that can read them, such as Safari on iPhone and Mac. The converter saves your results as JPG, PNG or WEBP. If you add an animated GIF, the result is a single still image.
Which Format Should You Choose?
JPG for photos
JPG gives small files for photographs and works almost everywhere, from social media to email. It does not support transparency.
PNG for screenshots, logos and graphics
PNG is lossless and keeps transparent backgrounds, which makes it a good fit for logos, icons and screenshots. Photos saved as PNG are usually much larger than JPG.
WEBP for websites
WEBP is a modern format that usually makes smaller files than JPG or PNG at similar quality, so pages load faster. All major current browsers can display it, but some older apps cannot open it.

Tips for Smaller Image Files
Phone photos are often 4000 pixels wide, while most websites only need 1200 to 1600 pixels. Enter a width in the resize box and convert to WEBP or JPG at 80 to 90 percent quality. You will usually cut the file size a lot without a visible difference.
Frequently Asked Questions
Is this image converter really free?
Yes. It is completely free, with no signup, no watermark and no limit on how many images you convert.
Are my photos uploaded to a server?
No. The conversion runs inside your browser, on your own device. Your images are never sent to our website or to anyone else.
How do I convert HEIC to JPG on iPhone?
Open this page in Safari on your iPhone, add your HEIC photos, choose JPG as the output format and tap Convert. Some other browsers cannot read HEIC files. You can also stop the problem at the source by going to Settings, Camera, Formats and choosing Most Compatible.
Will converting an image reduce its quality?
PNG is lossless, so converting to PNG keeps every pixel. JPG and WEBP are lossy formats. At around 90 percent quality the difference is hard to see, but converting the same file again and again between lossy formats slowly lowers quality, so keep your original.
What happens to a transparent background when I convert PNG to JPG?
JPG does not support transparency, so transparent areas are filled with white. Choose PNG or WEBP as the output format if you need to keep the transparency.
Can I convert many images at once?
Yes. Add as many files as you like, click Convert once, and then download each file separately or all of them together in one ZIP file.
