Which format should I use?
JPG is best for photographs and has the widest support of any image format: every device, app and upload form accepts it. It uses lossy compression, so each save loses a little detail, and it has no transparency. PNG is lossless and supports transparency, which makes it right for logos, icons, screenshots and anything with sharp text, but photos saved as PNG are often five to ten times larger than JPG. WebP supports both lossy and lossless compression plus transparency, and typically produces files 25 to 35 percent smaller than JPG at the same visual quality. Every current browser displays WebP, though some older desktop apps still cannot open it.
A good rule: use WebP on websites, JPG when sending photos to people or services, and PNG for graphics that need crisp edges or a transparent background.
Tips
- Converting a JPG to PNG does not restore lost detail; it only makes the file bigger. Convert from the best original you have.
- When converting a transparent PNG to JPG, transparent areas become white because JPG cannot store transparency.
- Got a WebP image that an app will not open? Convert it to JPG or PNG here.
- AVIF appears as an option automatically if your browser can create AVIF files.
Frequently asked questions
Does converting reduce image quality?
Converting to PNG is lossless. Converting to JPG or WebP applies lossy compression at the quality you choose; at 85 percent or higher the difference is hard to see for photos.
Are image dimensions changed?
No. The width and height stay the same. To make images smaller in pixels too, use the Image Compressor, which can resize while it compresses.
Is my data private?
Yes. The conversion uses your browser's own image engine, so files never leave your device and nothing is stored.
Why is photo metadata missing after converting?
Re-encoding with the browser drops EXIF data such as camera model and GPS location. That protects your privacy when sharing, but keep the original if you need the metadata.
