Convert Images Between JPG, PNG & WebP

Each image format has a specific use case. Picking the wrong one means either unnecessarily large files or quality loss you didn't intend.

JPG is the default for photos. PNG is for graphics, screenshots, or anything with transparency. WebP is the best all-around choice for web use — smaller than both JPG and PNG at comparable quality.

Use this table to pick the right format every time:

PNG is a lossless format. It's excellent for quality but produces large files, especially for photographs.

Converting PNG to JPG applies lossy compression, which typically reduces file size by 50–80% for photographic content. The quality trade-off is usually imperceptible for photos.

Important: JPG does not support transparency. When converting a PNG with a transparent background to JPG, transparent areas become white. If transparency matters, convert to WebP or keep the PNG.

WebP was developed by Google specifically for web use. It produces smaller file sizes than both JPG and PNG at comparable visual quality.

Converting JPG to WebP typically reduces file size by 25–35%. Converting PNG to WebP can reduce size by up to 80% for photographic content.

WebP supports both lossy compression (like JPG) and lossless compression (like PNG), as well as alpha-channel transparency. All modern browsers support WebP — Chrome, Firefox, Safari 14+, and Edge.

Use WebP for any image that will be displayed on a website. Smaller images mean faster load times, better Core Web Vitals scores, and lower bandwidth costs.

Format conversion and compression solve different problems and are often used together.

Format conversion changes the file type (e.g., PNG → JPG). The file size change is a side effect of the new format's compression method. A PNG converted to JPG will be smaller because JPG uses lossy compression.

Compression reduces file size within a format. Our Compress tool lets you hit an exact KB or MB target regardless of format — useful when a portal requires files under a specific size limit.

For the smallest possible JPG: convert from PNG or WebP first, then apply compression if you still need to hit a specific KB target.
