Bulk Image Compressor to 100KB or Less: preset, controls and batch workflow
The Image Compressor to 100KB or Less is designed for reducing image files to a practical maximum of 100KB. It applies the same maximum file-size goal to every selected image, which is useful for upload forms, email attachments, websites and document systems with strict KB or MB limits.
The target-size image compressor first searches for a suitable encoding quality and can reduce pixel dimensions when quality changes alone are not enough. Results are clearly marked against the target before individual or ZIP download.
Preset summary: file-size target: 100KB or less; accepted input: JPG, PNG & WebP. All selected files use the same configuration.
