About Morphjet

Morphjet is a file converter for Mac, Windows and Linux that does the work on your own computer. Files are read from and written back to your disk, and never travel over the network. You can check that claim the direct way: convert something with your wifi switched off. That is not a figure of speech, and you do not have to take it on faith either: the demo does it on camera, then converts a raw photo on a machine with no network.

Who makes it

I built Morphjet. Every conversion documented on this site is run end-to-end on macOS, Windows, and Linux against the shipping build before its guide goes up.

Sam Karia, Creator of Morphjet

The conversion guides and format explanations on this site are written alongside the app itself, by the same person who builds it. That is the reason they can be specific about what the app does and, more usefully, about what it does not do.

Converting is most of it, but not all of it. The app also compresses images to a target size, strips the hidden data out of photos, extracts and builds archives, carries a full PDF toolkit with on-device OCR, and runs speech to text, upscaling and background removal locally. Thefeatures page lists the lot, in seven languages.

What "tested" means here

This site counts 2,911 conversions. A conversion here means one source format going to one target format, so the figure counts pairs, not file formats. A conversion only enters the count once it has been verified on macOS, Windows and Linux. If the app offers one that hasn't passed on all three, it stays out of the number until it does.

Verified has a specific meaning. On each platform, the conversion was run end to end using the same converter downloads the app itself uses, and the output was checked. The result was recorded separately for each platform, never assumed from another platform or from a similar conversion. The full set was run on all three platforms in August 2026, and every conversion added since then was run on all three before the release that added it shipped. The most recent round was on 2026-09-27, for version 1.0.7. A conversion this site describes is one that has been run, not one that appears in a capability table.
