How it works

Use this preset when a form, portal, or website asks for an image under 350 KB. ResizeWizard keeps the workflow focused: upload, preview, compress, download.

Upload a JPG, PNG, or WebP image.
The 350 KB target is already selected.
Choose JPG or WebP for the smallest result, then process the image.
Download the optimized file and upload it wherever it is needed.

Tips for the best result

JPG is usually best for photos; PNG is best for screenshots and graphics.
If the original image is very large, combine resizing with compression for a sharper result.
For application forms, keep a copy of the original image before compressing.
