Your files stay on your Mac.
Convertessa renders each OpenDocument Sheet as a fixed-layout PDF, preserving fonts, grid lines, and cell formatting exactly as they appear on screen. Conversion runs fully offline — your files never leave your Mac. Convert a single .ods file or an entire folder in one pass.
Drag one or more .ods files — or a whole folder of them — onto Convertessa. Batch mode processes every spreadsheet in one go.
Select PDF from the output format list. Set quality to control the fidelity of any embedded images rendered into the document.
Click Convert. Convertessa renders each sheet to a fixed-layout PDF, strips document metadata, and saves the result alongside the original file.
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.
