Image Converter

Image Converter Online Free: Convert JPG, PNG and WebP in Your Browser

This free image converter changes your pictures between PNG, JPG and WebP in a few clicks. Everything runs inside your browser, so your files are never uploaded to a server. Choose an image, pick the output format, set the quality if you want a smaller file, and download the result.

How to use it

Click Choose image and select a file from your device.
Pick the output format: PNG, JPG or WebP.
Adjust the quality slider. Lower values give smaller files.
Optionally set a maximum width to shrink large images.
Click Convert and download the converted image.

Convert WebP to JPG Online, Even for Many Files

WebP is great for websites, but many apps, printers and older programs still expect JPG. To convert WebP to JPG, load the file, choose JPG as the output format and click Convert. The tool handles one image at a time, which keeps conversions fast and your device responsive. If you have a whole folder, work through the files one after another: the settings stay the same, so each extra image takes only a few seconds. Transparent areas in a WebP file become white in a JPG, because JPG does not support transparency.

How to Convert WebP to PNG with a Transparent Background

If your WebP image has a transparent background, convert it to PNG instead of JPG. PNG supports transparency, so logos, icons and cut-out product photos keep their see-through areas. Choose PNG as the output format and convert. Because PNG is lossless, the picture is not compressed again, so the file may be larger than the WebP original. That is normal and is the price of keeping every pixel and the transparency intact.

Convert AVIF to JPG Without Losing Quality

AVIF files are very small, but not every program can open them. Converting AVIF to JPG makes them work almost anywhere. JPG is a lossy format, so a perfectly identical copy is not possible, but you can keep the loss practically invisible. Choose JPG, set the quality slider to a high value such as 90 to 100, and avoid setting a maximum width unless you want a smaller picture. Convert once from the original AVIF rather than converting the same image several times, because each extra JPG save adds a little more compression.

Free Online AVIF to PNG Converter

When you need the best possible copy of an AVIF image, convert it to PNG. PNG is lossless, so no new compression artifacts are added, and it keeps any transparency from the original. This makes it a good choice for graphics, screenshots, logos and images you plan to edit further. Select PNG as the output format and convert. Expect a larger file than the AVIF original, since AVIF compresses far more efficiently. Your browser must be able to read AVIF files; current versions of Chrome, Edge, Firefox and Safari can.

Convert HEIC to WebP for Your Website

Photos from iPhones are often saved as HEIC, which web pages cannot display reliably. Converting them to WebP gives you a small, fast-loading image that works in all modern browsers. Choose WebP as the output format, set the quality to around 75 to 85, and set a maximum width that matches your layout, for example 1600 pixels. HEIC support depends on your browser: it works in Safari on iPhone, iPad and Mac, but many other browsers cannot open HEIC files. If your browser shows an error, convert the photo on an Apple device or export it as JPG first, then run it through this tool to get a WebP.

Which Format Should You Choose?

JPG: best for photos when you need maximum compatibility.
PNG: best for graphics, screenshots and anything that needs transparency or no quality loss.
WebP: best for websites, with smaller files than JPG or PNG at similar quality.

Frequently Asked Questions

Is the image converter really free? Yes. There are no sign-ups, watermarks or limits on how many images you convert.

Are my images uploaded anywhere? No. The conversion happens on your device, so your files stay private.

Why did my transparent image get a white background? JPG cannot store transparency. Convert to PNG or WebP to keep it.

Why is my PNG bigger than the original? PNG is lossless, so it often takes more space than a compressed WebP or AVIF.

What if my file will not open? Your browser may not support that format, which is most common with HEIC. Try another browser or convert the file to JPG first.
