The Image Format Converter transforms JPG, PNG, WebP, GIF, and BMP files into JPG, PNG, or WebP outputs while preserving original width and height dimensions.
Learn how to select the right output format for photos or graphics, how transparency is handled, and how quality adjustments affect JPEG, WebP, and PNG files.
JPEG is best suited for photographs due to efficient lossy compression. PNG is ideal for graphics, screenshots, and images requiring transparency. WebP offers high compression alongside alpha support, making it optimal for the web.
PNG and WebP images with transparent backgrounds preserve transparency when converted between each other. When converting a transparent image to JPEG, the alpha channel is removed and transparent pixels are filled with solid white.
For JPEG and WebP outputs, the quality setting adjusts lossy compression. For PNG, 100% preserves full truecolor lossless output, while values below 100% apply color palette quantization to reduce file size.
Upload multiple images to convert them all to the target format simultaneously and download the results as a single .zip archive. Mobile photo EXIF orientation is automatically corrected, and animated GIFs are converted using their first static frame.
Upload banner.png (transparent) and photo.jpg, set WebP output at 86 quality, and click convert. Download individual files or get all converted assets in a .zip archive.
banner.png + photo.jpg -> webp (86% quality)Images are sent to the server for accurate decoding and re-encoding using Pillow. Processing takes place strictly in memory during the request, and no files are written to disk or retained.
Because JPEG has no alpha channel, the converter automatically composites transparent pixels onto a solid white background. To preserve transparency, choose PNG or WebP as the output format.
At 100%, PNG output remains full truecolor. Below 100%, the converter quantizes the image palette to fewer colors, shrinking file size while preserving PNG structure.
No. Original pixel dimensions (width and height) remain unchanged throughout the format conversion process.
No. The converter extracts and re-encodes only the first static frame of an animated GIF to the selected format.
The tool reads embedded EXIF orientation metadata before processing and applies the correct rotation automatically in the output file.
