Compress JPG

JPEG uses lossy encoding that simplifies photographic detail people are less likely to notice. Lower quality settings discard more information and create smaller files, but excessive compression can introduce blocks, ringing, or banding.

There is no single best percentage. Start high, inspect the image at its intended viewing size, and lower quality gradually. Portraits, gradients, text overlays, and fine texture reveal compression damage at different rates.

Yes. Standard quality compression keeps the pixel width and height while re-encoding the file. A target-size workflow may reduce dimensions only when stronger encoding alone cannot reasonably reach the requested weight.

Very low quality removes fine contrast and texture, making hair, foliage, fabric, or small text appear soft. Enlarging a small source can add blur as well, so review both pixel dimensions and encoding quality.

Repeated lossy saves can accumulate artifacts because each export encodes an already simplified image. Keep the original file, make each delivery copy from that source, and avoid repeatedly editing and resaving the compressed result.

Use Target File Size when a portal or email sets a maximum. The tool tries to approach that weight, but complex photos may need lower quality or reduced dimensions, and an extremely small target may not remain visually useful.

WebP can produce a smaller modern web asset at comparable visual quality, but JPG remains broadly accepted by photo services and older workflows. Choose based on the destination rather than file size alone.

No. JPEG has no transparency channel, so transparent areas must be filled with a solid background during conversion. Use PNG or compatible WebP output when the destination needs cutouts, soft transparency, or clear corners.
