Frequently asked questions

Is this a subscription?

No. Image Quality Booster is a one-time purchase ($5.99). All features and updates are included with no recurring fees.

Does it use the cloud?

No. Image Quality Booster runs entirely on your Mac. Every adjustment runs locally in Metal and CoreImage — your photos never leave your computer. No account, no internet connection required.

Can I batch-process an entire folder?

Yes. Grade and export an entire folder with your current canvas settings in one pass. Every export matches the live preview — WYSIWYG parity guaranteed. You can also generate multiple aspect ratios (1:1, 4:3, 16:9, 9:16) in a single export step.

What file formats can I export?

JPEG, PNG, TIFF, and HEIC. JPEG and HEIC support quality control — tune compression to balance file size and fidelity. Choose the format that best fits your workflow.

Can I save my work and come back to it later?

Yes. Save full sessions as .biqb project files — they preserve all layers, adjustments, text, and settings. You can also take named snapshots (branches) of any canvas state to revert or compare versions, or export a watermarked proof for client review.
