Compress Images to a Specific KB Size
Online forms often ask for a clear photo under a specific KB limit. Choose a preset target from 10KB to 2MB before uploading, then review the compressed result before you submit. The flow stays focused on the file limit you actually need.
Compare Images Before and After Compression
A smaller KB file still needs to look usable for IDs, certificates, or product photos. Compare the original and compressed version, including file size, dimensions, and saved percentage, before downloading. This helps you catch blurry text or weak details early.
Batch Compress Images to KB Sizes
When you have a folder of heavy JPEG, PNG, or WebP files, processing them one by one slows you down. Upload multiple images up to 50MB each and apply the same KB target across the batch. It is useful for application sets, profile photos, and web image cleanup.
