Image Format Converter: JPG vs PNG vs WebP vs GIF Guide
Image format conversion changes a file between JPG, PNG, WebP, GIF, and other formats. Picking the right format balances quality, size, and compatibility.
When to Convert
Convert when a format no longer fits its purpose—a transparent PNG used as a photo, or a heavy TIFF for the web. The right format reduces size without visible loss.
Format Cheat Sheet
JPG for photos, PNG for transparency and text, WebP for the best web balance, GIF for simple animations. Convert based on how the image will be used, not habit.
Batch Conversion
Converting one by one wastes time. Batch tools apply the same format and quality settings to every file, keeping a consistent result across a set of images.
Quality Settings
When converting to a lossy format, choose a quality level you can inspect visually. Start high and step down until the file size target is met.
Transparency and Backgrounds
PNG and WebP support transparency, while JPG always fills the frame with a background color. If your image needs a transparent background, convert to a format that preserves the alpha channel.
When converting a transparent PNG to JPG, fill the background first—otherwise the transparent areas render as black or white unpredictably across viewers.
How to Convert an Image
- Upload or select the source image file.
- Choose the target format and a quality setting that fits the use.
- Convert and compare the output size and appearance with the original.
Convert from the original rather than from an already-compressed copy to avoid losing another generation of quality.
Quick tip: standardize on WebP for web images unless you need transparency in legacy tools. It consistently beats JPG and PNG on size at the same visual quality. Modern browsers render WebP perfectly at smaller sizes, with no visible quality loss.
