What is the Image Converter?
Some websites reject WebP images, some forms need JPG only, and designers often need PNG. The image converter changes the format of one image or a whole batch.
Everything happens inside your browser. Your files are never uploaded to our server, so contracts, CNIC scans, bank statements and personal photos stay on your device.
Transparent PNG images get a white background when converted to JPG. To shrink files at the same time, use the Image Compressor.
How to use the Image Converter
- Choose the output format: JPG, PNG or WebP.
- Set the quality for JPG or WebP.
- Drop your images onto the box.
- Download each file or all of them as a ZIP.
Example
A WebP image saved from a website becomes a JPG that you can upload to a form that only accepts JPG.
Which format should I use?
JPG / JPEG
Photos and anything that needs to be small and widely accepted.
PNG
Logos, screenshots, text images and anything with a transparent background.
WebP
Websites: smaller files at the same quality, supported by all modern browsers.
Converting for uploads and websites
Most government and job portals accept only JPG or PNG, so convert HEIC photos from iPhones or WebP images saved from websites before uploading. For a website, WebP usually gives the smallest file at the same visual quality. If the converted file is still too large, run it through the Image Compressor, and if you need several images in one document, use JPG to PDF.
