Your files stay on your Mac.
SVG is a resolution-independent vector format; TIFF is a lossless raster format built for print, archival, and image-editing pipelines. Convertessa renders each SVG at full resolution and writes a pixel-perfect TIFF file — entirely on your Mac, with no upload step. Metadata is stripped from every output file.
Drag one SVG file or an entire folder onto Convertessa. The app finds every .svg inside automatically.
Pick TIFF from the output format list. TIFF is lossless, so every pixel is preserved exactly as rendered.
Click Convert. Each SVG is rendered at full resolution and saved as a TIFF beside the originals. Files never leave your Mac.
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.

No. TIFF is a lossless format. Convertessa renders the SVG at full resolution and writes a pixel-perfect TIFF — no compression artifacts.
Yes. Drop a folder onto Convertessa or run convertessa /path/to/folder --to tiff in the terminal. Every .svg inside is converted in one pass.
Yes. Convertessa strips metadata from every output TIFF. Your source SVG files are not modified.
