JPG, PNG, or WebP: choose an image format
Choose a format for the way an image will be used. The smallest file is not always the best result.
JPG for photographs
JPEG usually compresses photographs efficiently. It does not retain transparency, and lowering quality introduces irreversible visual changes. Repeated editing and exporting can add artifacts, so start from the original whenever possible.
PNG for transparency and sharp graphics
PNG is useful for screenshots, line art, transparent logos, and images where sharp edges matter. It is lossless, but photographs can become much larger than equivalent JPEG or WebP files.
WebP for supported web workflows
WebP supports efficient image compression and transparency. Current browsers commonly support it, but an older application or an upload form may require another format. Check the destination’s accepted file types.
Convert with a purpose
- Open Convert Image.
- Choose the output format based on the destination.
- Review transparency, colors, dimensions, and file size.
- Download the result and open it in the application where it will be used.
Changing the extension is not conversion
Renaming a PNG file to .jpg does not change the bytes inside it. A proper conversion decodes the source and encodes a new file. The file extension, MIME type, and actual output format should agree.
