The Image Converter changes a picture from one format to another — PNG to JPG, JPG to WebP, WebP to PNG and so on. Different websites and apps accept different formats, and converting takes one click here instead of re-exporting the image from a heavy editor.
Which format should I choose?
JPG is the safest choice for photos and uploads almost anywhere. PNG keeps sharp edges and transparency, best for logos and screenshots. WebP gives the smallest files for websites, but some older apps cannot open it.
Why does converting PNG to JPG change the background?
JPG does not support transparency, so transparent areas are filled with a solid colour in the JPG. If your logo must stay transparent, convert to PNG or WebP instead.
Are my files uploaded to a server?
No. The Image Converter runs entirely in your browser — your file is processed on your own device and is never sent to ToolNest or anywhere else. Close the tab and everything is cleared.
