Convert Image changes the format of your pictures between JPG, PNG and WebP. It is useful for web publishing, uploads that accept only certain formats, and for saving space.
Convert images between JPG, PNG and WebP
Different tasks need different image formats. A website may prefer WebP, a document editor may want PNG and an old application may only understand JPG. This converter switches your pictures between these three popular formats in seconds, and handles many files at once. Everything is done in the browser.
Understanding the formats
JPG (JPEG) is the standard format for photos. It gives small files by discarding invisible detail, and it does not support transparency. It is accepted almost everywhere.
PNG is lossless, so it keeps every pixel exactly. It supports transparent backgrounds and is ideal for logos, icons, screenshots and graphics with sharp lines. File sizes for photos are large.
WebP is a modern format developed for the web. It supports both lossy and lossless compression and transparency, and usually creates smaller files than JPG or PNG. All current browsers can show it, but some older software cannot open it.
Common reasons to convert
- Website speed. Converting JPG or PNG to WebP can lower page weight.
- Cannot open WebP. Images saved from the web are often WebP. Convert them to JPG or PNG for editing programs and document tools.
- Transparent logos. Convert a JPG logo to PNG when you need a transparent background after editing.
- Upload requirements. Some forms accept only JPG.
- Sharing. JPG is the safest choice for messaging apps and email.
About transparency
Converting a PNG or WebP with transparent areas into JPG fills those areas with white, because JPG cannot store transparency. Converting JPG to PNG does not create transparency; the picture stays rectangular, only in a lossless wrapper. Removing a background needs a separate editing step.
The quality setting
The quality value applies to JPG and WebP. A value of 90 is a good default with very high visual quality. Lower it to around 75 for smaller files. PNG ignores this setting because it is lossless.
How it works
Your browser decodes each picture, draws it on a canvas and encodes it again in the format you picked. This happens locally, so there is no waiting for uploads and no server involved.
Privacy
Your pictures are not uploaded anywhere. They stay in your browser until you download the results.
Tips
- Convert from the original file when possible. Repeated conversions between lossy formats reduce quality.
- For screenshots and graphics with text, PNG usually looks sharper than JPG.
- For photos on a website, WebP at quality 75 to 85 is often the best choice.
- Check that the target software supports the format before converting many files.
Troubleshooting
My browser cannot create WebP. Very old browsers lack this feature. Choose JPG or PNG.
The picture got bigger after converting to PNG. This is normal. PNG stores every pixel, so photos become large.
Transparent parts are white. You converted to JPG. Choose PNG or WebP to keep transparency.
Free and unlimited
Choose your images, pick the target format and download them. No sign-up and no limits.
A real-world example
Sana saves a picture from a website and finds that it is a WebP file that her presentation software will not open. She selects the file, chooses PNG and downloads a version that works everywhere. Later, for her own blog, she converts several large PNG screenshots to WebP at quality 80 and notices her pages load noticeably faster.
