Change an image to JPEG, PNG or WebP
Choose your source images and select the desired output format. For a transparent source, use PNG or WebP to keep transparency, or choose a background color for JPEG.
Changing format does not add lost detail. JPEG is useful for photos, PNG for sharp graphics or transparency, and WebP for a smaller modern web image when supported by the destination.
JPEG and WebP quality settings can reduce file size; PNG is lossless and does not use the quality setting. Results may be larger than the original, so compare the displayed sizes. Re-encoding removes most metadata and preserves only the first frame of animated WebP files. JPEG replaces transparency with your chosen background.
Common image questions
Why is the output larger than my original?
The original may already be compressed efficiently. Dimensions, format and quality all affect file size. Compare the displayed sizes, and try JPEG or WebP if suitable for your image.
What if my file will not open?
Use JPEG, PNG or WebP within the limits shown by the tool. Renaming a file extension does not convert it. Try one smaller file if a large batch fails; your browser may not have enough memory.
Where is my processed image?
After processing, use the download link in the results. Check your browser’s download list or your phone’s Files app. Processing on this page does not save your images to a BZ WorkOps account.
