About DashUtils Blog
This blog is written by the team behind DashUtils: free online tools for converting, compressing and editing images, PDFs, video and audio.
What you'll find here
Practical guides to everyday file problems:
- Making a favicon or Windows icon from a PNG
- Turning a video into a GIF that isn't huge
- Shrinking a photo to fit an upload limit like 50 KB or 100 KB
- Choosing between formats like JPG, PNG, WebP and AVIF
Each guide is based on real tests. Where file size or quality matters, we convert the files ourselves and report the numbers, so you can see the trade-offs before you start.
Why DashUtils is different
Most online converters upload your file to a server. DashUtils tools run entirely in your browser: your images, PDFs and videos never leave your device. There's no sign-up, no watermark, and you can convert files in batches.
