JPG is still the universal choice for photographs. It is lossy, so it discards detail the eye is unlikely to notice. It has no transparency, and at quality 70–85 it usually gives the best balance of size and appearance. PNG is lossless and supports transparency, which makes it ideal for screenshots, logos and UI graphics. It produces large files for photos.

WebP and AVIF are modern formats supported by all current major browsers. WebP is typically 25–35% smaller than an equivalent JPG and supports transparency. AVIF often goes further at the same visual quality, but it is slower to encode, and not every browser can create AVIF files yet. For websites, serving WebP or AVIF is one of the simplest performance wins available.

The biggest saving almost always comes from dimensions, not quality. A 12-megapixel phone photo is about 4000×3000 pixels, while most web layouts display images at 1200–2000 pixels wide. Halving the width and height cuts the pixel count by 75%, before any compression is applied.

A practical workflow is to resize to the largest size the image will actually be shown at, then compress to a quality of around 75–80%. Convert to WebP if the destination supports it. The Batch Image Processor combines all three steps in one pass.

Photos taken on phones and cameras often carry EXIF metadata, including the exact GPS location, the date and time, and the device model. Re-encoding an image through the browser, as the compressor, converter and EXIF Remover do, drops this metadata while applying the correct orientation to the pixels.
