Your files stay on your Mac.
Converting a PSD to TIFF flattens the Photoshop composite into a single-layer image that any print shop, archive system, or design app can open without Photoshop. TIFF is a lossless format, so it carries full color data from the source file without degradation. Everything runs locally—no file ever leaves your Mac.
Drag a single PSD or an entire folder into Convertessa. Batch mode queues every file for conversion in one pass.
Choose TIFF from the output list. Convertessa converts to the format you select—nothing is pre-set or auto-detected.
Click Convert. Convertessa exports each PSD as a full-resolution TIFF, stripping embedded EXIF metadata along the way. Files never leave your machine.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.
