Right-click the photo and it's already open. Crop it, pick quality and format, WebP and AVIF included, and see what it'll weigh before you save.
Start, end and framing, just like in QuickTime. Drop the audio, lower the bitrate: from 229.6 MB to a few MB, ready to post.
MP3, AAC, Opus, FLAC or WAV: one click, with a line under each saying what it’s for. The soundtrack of a video, too.
From 11.7 MB to 2.1 MB: the PDF that wouldn’t send now goes through. And nothing gets uploaded anywhere.
How it works
Convertion lives in the Finder’s menu. Right-click a file, choose Convertion, and it opens ready for that file: a photo, a video, a track or a PDF.
JPG · PNG · WebP · AVIF
Photos too heavy for your site or an email? Shrink them, crop them and see straight away what they’ll weigh. iPhone photos too.
MP4 · WebM · H.264 · HEVC
A video of hundreds of MB comes down to a few, ready for WhatsApp, Instagram or your site. And you trim the start and end.
MP3 · AAC · Opus · FLAC · WAV
A song, a podcast, a voice note: get it into the format you need. And pull the audio out of a video as a file of its own.
Lighter, same text
PDF too big for email? Slim it down in a moment, and the text stays text, ready to copy and search.
Photos · Audio · PDF
Select every photo in a folder, right-click, Convertion: it handles them all with the same settings while you get on with something else. Same with audio and PDFs.
On your Mac
No uploads. Every conversion happens on your computer, even offline.
