About

100KB Camera

Features
Read full description

100KB Camera is a simple camera app that captures and saves each photo as an exactly 100KB JPEG. At 100KB each, 10 photos add up to 1MB, and 10,000 photos add up to 1GB. Before saving, zoom into the actual JPEG to check whether text on receipts or notes is readable. You can also select multiple photos from your library and convert them in one batch. The new photos retain the original capture date and location. After saving, you can choose whether to keep or delete the originals. Features • Capture and save exactly 100KB JPEGs • Choose whether to record the capture location • Preview an approximation of the saved quality while shooting • Tap to focus; pinch or use the button to zoom • Review and zoom into the photo’s actual JPEG before saving, or skip the review screen in Settings • Batch-convert multiple photos • Save to Photos Capturing and converting photos happens on your iPhone. Images are not sent to the developer's server. 100KB Camera Pro is a one-time purchase. It unlocks 50KB and 500KB for both shooting and photo conversion. It is not a subscription. Note: As on iOS, this app writes the unit as “KB”. Here, 100KB means 100,000 bytes; strictly, the symbol is 100kB. The 50KB, 100KB and 500KB sizes refer only to the JPEG file itself, not thumbnails or library management data used by Photos. Terms of Use https://apps.mishimadesign.com/kbcamera/legal.html#terms-en
