We've all been there. You have a folder of 150 PNG icons or totally uncompressed photos from a camera, and you need them all to be JPEGs or WebPs for a website.
The worst thing you can do right now is open your default photo viewer, hit "Save As," select JPEG, save it, and then move to the next file. You will lose an hour of your life that you will never get back.
The Old Way (Desktop Software)
For a long time, the solution was to download some clunky desktop app that looked like it was built in 1998, figure out its weird interface, and hope it didn't watermark all your photos. Don't do this either.
The New Way (Browser Batching)
Because modern web browsers are basically operating systems now, you can do all of this directly in a tab. Specifically:
- Open up the ConvertFree4U Image Converter.
- Highlight all 150 of your images (or just grab the whole folder) and drag them into the upload box.
- Select your output format once. Let's say, WebP at 80% quality.
- Hit convert.
What Happens Next?
Instead of uploading those 150 images to an external server (which would take forever), the converter uses your computer's own processor to churn through them. It usually chews through about 5-10 images per second depending on your device. Once it's done, it zips them all up into one neat folder for you to download.
Stop punishing yourself and just drag-and-drop. It's totally free, incredibly fast, and actually preserves your privacy.
