All Video & Audio Tools

Choosing the right tool for the job

Each NextConvert tool is built for one specific operation, with sensible defaults so you don’t need to know the underlying FFmpeg switches to get a good result. The tools above are grouped roughly into five families: format conversion (changing what container or codec your media uses), size and quality (compress, resize), editing (trim, crop, merge, split, rotate, speed), audio (extract, add, remove, noise reduction, convert), and branding (watermark, video-to-GIF).

If you’re not sure where to start: Compress is the right tool for shrinking a file that’s too big to share, and Convert is the right tool when a file simply won’t play in the place you need it. Use Trim to cut start / end fluff, and Crop when you need to reframe a landscape clip into a vertical one for Reels / Shorts / TikTok.

Compress vs convert vs resize: the difference

These three operations get confused often, so it’s worth being precise. Compress reduces file size by re-encoding the same picture at a lower bitrate. The resolution and format stay the same, only the data per frame goes down. Convert changes the format (container and/or codec) without necessarily affecting size or quality. Resize changes the actual pixel dimensions of the frame, going from 4K to 1080p for example.

In practice you often want two of them: compress + convert if you need a smaller MP4 from an MOV input, or resize + compress to take a 4K phone recording down to a sub-25 MB clip you can email. Either way, run each step here and we’ll pipeline them on our end so you only pay one upload / download round trip.

Where each tool runs

All processing happens on our cloud workers. Each tool calls into FFmpeg with a curated set of parameters chosen for that specific operation. We don’t hand you a thousand knobs and a manual. Hardware acceleration (NVENC / VA-API) is used where it’s the right choice; software encoding is used where quality matters more than speed. The same tool produces the same result regardless of what device you’re using to upload from.

We pick the lossless path whenever the operation allows it. For example, trimming between keyframes is stream-copy rather than re-encode, and removing audio doesn’t touch the video stream at all. Where a re-encode is unavoidable, we default to near-transparent quality so the output is visually identical to the source for ordinary viewing.

Privacy across every tool

Privacy is uniform across the toolkit. Uploads are HTTPS-encrypted, files are stored encrypted at rest, processing workers don’t persist intermediate state, and the original file is deleted automatically within hours of job completion. We never train models on your media, sell metadata, or scan content for any purpose beyond running the job you asked for. Read our privacy policy for retention details and our list of subprocessors.
