## What is LessKB?

LessKB is an offline image compressor built around file-size limits.

Choose an image and a target size. LessKB processes it locally and produces an image that stays within your selected limit—ideal for application forms, ID photos, website uploads, and email attachments.

Features
• Continuous target control from 100 KB up to the original size
• Automatic compression after selection or target adjustment
• Clear before-and-after file-size comparison
• Full-screen zoom inspection for original and compressed images
• PNG, JPEG, and HEIC output
• Keep metadata, remove GPS only, or remove all metadata
• Import from Photos or Files
• Save to Photos or share through the system sheet
• On-device compression history for quick adjustments
• Compress an image from the iOS share sheet
• Batch-compress photos with simple space-saving presets
• Inspect original and compressed versions for each batch result
• Save compressed copies first, then choose whether to remove originals

Privacy first
Compression happens entirely on your device. Images are never uploaded to LessKB or developer-operated servers. Images in compression history stay in the app's local storage and can be cleared at any time.

The free version processes up to five newly selected single photos per day and includes one saved batch of up to five photos each day. LessKB Pro is a one-time purchase that unlocks unlimited single-photo compression, unlimited batches, and up to 100 photos per batch. It is not a subscription.
