Understanding the Three Formats
JPG (JPEG)
The most widely supported image format. JPG uses lossy compression: it discards some data to reduce file size. This works well for photos, where small losses aren't noticeable. It is a poor choice for images with sharp text, logos, or transparency. JPG doesn't support transparency at all, so transparent areas become white.
PNG
PNG uses lossless compression, so no detail is discarded. It supports transparency, which makes it a good fit for logos, icons, and images with text. The downside is size: for photos, a PNG is often several times larger than the same picture as a JPG. Use PNG when quality and transparency matter more than file size.
WebP
WebP is a modern image format developed by Google. Google reports that lossy WebP files are roughly 25–34% smaller than comparable JPG files, and WebP also supports transparency like PNG. All current major browsers can display it. It is a strong choice for websites, although some older apps and forms still don't accept it.
Common Conversions
- PNG to JPG: Makes screenshots and photos smaller. Transparent areas become white, and sharp text can look slightly soft.
- JPG to PNG: Needed when a tool asks for PNG. It does not improve quality, and the file gets larger.
- WebP to JPG: The fix for downloaded pictures that an app or form won't accept.
- WebP to PNG: Keeps transparency in a format that works almost everywhere.
- JPG to WebP: Usually gives a smaller file for a website.
- PNG to WebP: Often much smaller than the PNG, and keeps transparency.
Common Use Cases
1. Making a Website Faster
Converting images to WebP is one of the quickest ways to shrink a website's images. Smaller images load faster, especially across dozens of images on a page. The tool shows the exact size change for every image you convert.
2. Meeting a Form's Format Requirement
Many online forms and portals accept only JPG. Convert your PNG or WebP picture to JPG here, then reduce its size with the Image Compressor if the form has a size limit.
3. Saving Space on Your Phone or Computer
Screenshots of photos or busy content are often much smaller as JPG. Screenshots of plain text and flat colors may not shrink much, and JPG can blur sharp text, so compare the result before you delete the original.
4. Preparing Images for Social Media and Documents
Different platforms and apps accept different formats. Convert to the format a platform asks for before you upload, and check its current requirements.
5. Removing Transparency (JPG Output)
If you have a PNG with transparency and need a JPG, converting here fills the transparent areas with white. This is useful when a platform doesn't accept PNG.
6. Preparing Images for a CMS
Some content management systems create WebP versions of uploaded images automatically. If yours doesn't, or you want to control the quality, converting to WebP before you upload gives you more control.
A Worked Example
Say a job portal rejects your picture because it is a WebP file:
- Drop the WebP picture on the upload area.
- Choose "JPG (JPEG)" under "Convert to" and keep quality at 90%.
- Click "Convert Image".
- Compare the two sizes shown above the previews. The tool tells you whether the file got smaller or larger.
- Download the JPG. If the portal also has a size limit, run it through the Image Compressor.
The exact sizes depend on your picture, which is why the tool shows them for every conversion instead of promising a fixed saving.
Frequently Asked Questions
Which format should I use?
Use JPG for photos (smaller files), PNG for images with transparency, sharp text, or flat colors, and WebP when you want small files with good quality on modern browsers and websites. If a form or app asks for a specific format, use that one.
How do I convert WebP to JPG?
Choose the WebP image, select "JPG (JPEG)" under "Convert to", and click Convert Image. Then download the JPG. This is the usual fix when a downloaded picture is saved as WebP and an app or form will not accept it.
Does converting affect image quality?
JPG and WebP are lossy formats, so they discard some detail to reduce size, and PNG is lossless. Use a high quality setting (90% or more) to keep the result close to the original. Converting a lossy image such as a JPG to PNG does not bring back detail that is already gone, it only makes the file larger.
What happens to transparent areas when converting to JPG?
JPG doesn't support transparency, so transparent areas are filled with white. If you need to keep transparency, convert to PNG or WebP instead.
Why is the WebP option greyed out?
Some browsers cannot create WebP files. If the option is greyed out, use a recent version of Chrome, Edge, or Firefox. You can still convert to JPG or PNG.
Does the converted image keep its camera and location data?
Usually not. The image is drawn onto a canvas and saved again in your browser, which normally drops metadata such as camera details and GPS location. Check the downloaded file if this matters to you.
Are my images uploaded to a server?
No. All conversion happens in your browser. Your images never leave your device.
Is there a limit on image size?
Files up to 20 MB are accepted. Very large photos, with tens of megapixels, can fail on phones whose browsers limit how big an image can be processed. If that happens, shrink the image first with the Image Resizer.
Can I convert to a format other than JPG, PNG, or WebP?
No. This tool reads and writes JPG, PNG, and WebP. For other formats such as BMP, TIFF, or HEIC, you will need a different tool.
Is this tool free?
Yes. It is free, needs no signup, and has no limits.
