About Image Format Converter
Konvity’s image format converter changes an image into JPG, PNG, WebP, or BMP, right in your browser. It accepts a wide range of input files too, including JPG, PNG, WebP, BMP, GIF, and AVIF, so you can drop in almost any common image. Pick the output format you need and see a live preview before you download it.
For JPG and WebP output, you can adjust the quality level to balance file size against visual detail. PNG and BMP stay lossless. Everything runs on your own device: nothing is uploaded to a server, so your images stay private.
Whether you need to convert JPG to PNG online for a design project, turn a PNG to WebP for a faster website, or just need a reliable free image converter for one-off tasks, this tool covers all of it with the same simple flow. There is no software to install, no account to sign up for, and no daily limit on conversions. Because everything runs in your browser using the Canvas API, the same page works whether you are on Windows, macOS, Linux, or a mobile browser.
Common Use Cases
Convert PNG to JPG to shrink file size
Photos exported as PNG can be much larger than they need to be. Convert them to JPG and adjust the quality slider to get a smaller file that still looks good.
Convert images to WebP for a faster website
WebP files are usually smaller than JPG or PNG at the same visual quality, which helps pages load faster. Convert your JPG or PNG assets to WebP before uploading them to a site.
Get a JPG or PNG when a site requires it
Some sites and forms only accept older formats like JPG or PNG. If your image is saved as WebP, convert it back to a widely supported format in a few clicks.
Prepare images for older software
BMP and plain JPG are still expected by some older programs, printers, or embedded systems. Convert a modern PNG or WebP file into one of these formats so it opens correctly.
Add a background before converting to JPG
JPG does not support transparency. When you convert a PNG with a transparent background to JPG, a white background is added automatically so the image still looks right.
Convert a GIF or AVIF image to a common format
Not every site or program accepts newer formats like AVIF, or animated-only formats like GIF. Convert the first frame of a GIF, or an AVIF photo, into JPG, PNG, WebP, or BMP so it opens anywhere.
Frequently Asked Questions
Which image formats are supported?
Konvity supports JPG/JPEG, PNG, WebP, and BMP formats for both input and output conversion.
Does converting to JPG affect image quality?
JPG uses lossy compression, so some quality loss occurs. Use the quality slider (80-95%) to balance file size and visual quality. PNG and WebP offer lossless options.
Is there a file size limit for images?
There is no hard limit. Very large images (50MB+) may take a few seconds to process depending on your device.
Why convert to WebP?
WebP provides superior compression compared to JPG and PNG, resulting in smaller file sizes with similar visual quality. It is a good choice for web use.
Is this image converter free to use?
Yes. This free image converter has no account, no watermark, and no limit on how many images you convert.
Can I convert a GIF or AVIF file with this tool?
Yes, both are accepted as input. Since the conversion is based on what a single frame looks like, an animated GIF converts to a still image using its first frame.
