Privacy and practical limits

Image data and metadata processing stay on your Mac. No image uploads, app analytics or account.

Input decoding and output encoding capabilities vary by macOS format support. Preview reflects the encoded result. Original files are preserved; inspect colour, metadata and output sizes.

Features in practice

The feature list describes the available tools. These examples explain how they support a practical workflow, what to review and where the limits matter.

Prepare images for a destination

Convert supported inputs and choose available encoders, compression quality and output sizes. Format availability depends on the installed codecs and the source image.

Compare before exporting

Single, side-by-side and wipe previews, zoom controls and an expanded viewer help inspect changes. Judge the saved output at an appropriate scale rather than relying only on a thumbnail.

Repeat an editing pipeline

Combine resizing, cropping, padding, watermarks and naming operations; use presets and multiple output variants for repeated work. Review the order because it can change the result.

Inspect output and metadata

Use measured file sizes, per-item results and local history to review a batch. Metadata sanitisation helps prepare sharing copies; check which fields are retained for your selected format.

Use the compatibility, access and limitation information on this page when choosing a workflow. Sample screenshots illustrate the app; their records and measured results are not a scan of your own Mac.
