Convert files on your Mac
Step-by-step pages for the conversions people look up most, done with Macsential's file converter. Files are converted on your Mac and never uploaded, and each page shows what happened to a real sample file.
- HEIC to PNG Turn iPhone photos into PNG files that open everywhere, without losing any quality.
- JPG to PNG Get a PNG copy of a photo for editing or for apps that require PNG, losing nothing further.
- MOV to MP4 Turn QuickTime and iPhone movies into MP4 files that play on Windows, Android and the web.
- PNG to JPG Make screenshots and graphics small enough to email or upload, with control over quality.
- PNG to WEBP Make images smaller for websites, keeping transparency, even though macOS can't save WebP.
- WEBP to JPG Turn images saved from the web into JPGs that every app and upload form accepts.
- WEBP to PNG Save web images as lossless PNGs for editing, keeping transparent backgrounds.
How we measure
Each page's numbers come from one run of our benchmark script on one sample file: a 12 MP iPhone photo with its camera and location data, a Retina screenshot of a web page, and a 30-second 1080p QuickTime movie. The script converts each sample three times with the same code Macsential uses, at the app's default settings, keeps the middle time, and compares the metadata before and after with exiftool and ffprobe. They are examples, not promises: your files and your Mac will give different numbers.
