PBR Resizer

PBR Resizer helps reduce the size of photos, videos, PDFs, and supported Noteshelf notebooks on iPhone and iPad.

Adjust photo and video settings individually, or select multiple photos, videos, or PDFs for automatic compression. Batch results are accepted only when the output is smaller. Review results before choosing Replace, Keep Both, or Cancel.

Open files from an authorized source folder and save beside the original. Keep Both preserves your original while you test a compressed copy. Find Duplicates is available within each compressor, with file sizes and reviewable cleanup actions.

Noteshelf optimization targets supported embedded PNG images while preserving the notebook's other stored content. Embedded PDFs may remain unchanged. Open optimized notebooks in Noteshelf to verify appearance and editing before removing an original.

An optional iCloud library uses your own iCloud account. Availability depends on settings, connection, and storage. Compression savings and supported operations vary by file.
