Create without Adobe (free n' paid) 2025

There is no doubt that Adobe Suite is great, even in some case it's probably the best. But you can be mad at Adobe for many reasons, expensive monthly subscribtion method, bad stability, useless features, paying for tools you don't use. Here is my list with the best way to ditch Adobe monopoly in my opinion. I tried to add Open Source alternatives too as some are really good.

What is Mastershot?

Mastershot is a set of free video tools that run in the browser: compress a video to a target size, trim, crop, resize, change speed, remove or extract audio, convert between formats (MOV, MKV, WebM, AVI, GIF and more to MP4), make GIFs, add text or subtitles. The file is processed on your own computer with WebCodecs, so nothing is uploaded. There is no account, no watermark, no paid tier and no file-size cap beyond what your browser can handle. Several tools also take a batch of files at once.

Mastershot Studio is the full editor on the same site: a timeline with several rows, transitions, text, music, and AI tools that also run on the device, such as automatic subtitles, silence and filler-word removal, background removal, noise removal and face blurring. Studio is free as well; it signs you in so your projects are saved.

Mastershot started in 2021 as a browser video editor and was rebuilt in 2026 as this set of tools plus Studio. It works best in Chrome and Edge, with most tools also working in Firefox and Safari.
