Your files stay on your Mac.
SVG is a vector format — Convertessa renders it to pixels and writes a flat JPG. The output resolution matches the SVG viewport exactly, so nothing is stretched or distorted. Because JPG is lossy, you can set the quality level before converting.
Drag one SVG or an entire folder onto Convertessa. Every file stays on your Mac — nothing is uploaded.
Choose JPG from the output format list. Set the quality level to balance file size and image fidelity.
Click Convert. Convertessa rasterizes each SVG and writes the JPG files to the same folder, ready to use.
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.

New formats, new features, and fixes — every release, on the record.
No. Convertessa renders the SVG at the size defined by its viewport. The raster resolution in the output JPG is determined entirely by the SVG file itself — Convertessa does not alter it.
Yes. Drop a folder onto Convertessa or run convertessa ./folder --to jpg in the terminal to convert every SVG inside it in one pass.
No. All conversion happens locally on your Mac. Your files never leave your machine.
