ImgNexa is a set of free online tools for everyday image jobs: changing a file format, resizing a photo, cropping it to a shape, putting photos into a PDF and pulling the sound out of an MP4 video. We built it because these small jobs should take a few seconds, not an account, an install or an upload to someone else’s server.
How it works
Every tool runs in your web browser. When you add a file, it is read and processed on your own device, and the result is offered as a download. Your images and videos are not sent to ImgNexa, which keeps them private and makes the tools fast even on a slow connection.
What you can do
- Convert JPG to PNG for lossless editing.
- Convert PNG to JPG to reduce file size.
- Convert WebP images to JPG or PNG so they open everywhere.
- Resize images to popular social media sizes or your own size.
- Crop images to a square, portrait or widescreen shape.
- Combine photos into one PDF.
- Extract the audio from an MP4 video as MP3 or WAV.
Our approach
The tools are free, with no sign-up and no watermark. Each tool page explains what the tool does, what it cannot do and how to get the best result, and the guides on this site go deeper on formats, sizes and file quality. We keep the pages accurate and update them when a tool changes.
Advertising
The site may show Google AdSense ads to cover hosting costs. Ads never change how the tools work. See the Privacy Policy for details.
