Your files stay on your Mac.
3GP is a compact video container used by mobile phones and older cameras. Converting to GIF extracts every frame and assembles them into a looping, palette-mapped animation. Convertessa does the whole job on your Mac—your video file never leaves the device.
Drag one 3GP file or an entire folder of clips onto Convertessa. Batch mode queues every file automatically.
Pick GIF from the output format list. Convertessa reads the 3GP stream and maps each video frame to a 256-colour GIF palette.
Click Convert. Convertessa processes every frame locally and writes a looping animated GIF 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.

New formats, new features, and fixes — every release, on the record.
No. GIF is a silent format—it stores only image frames. Any audio track in the 3GP file is discarded during conversion.
Yes. Convertessa sets the loop count to infinite by default, so the animated GIF replays automatically in browsers and image viewers that support animation.
Yes. Drop a folder onto Convertessa or use the CLI batch command: convertessa ./clips --to gif. Every 3GP file in the folder is converted and saved as a separate GIF.
