How to use Convert Image
Choose your image
Click the box above or drop one image onto it. JPG, PNG, WebP and GIF all work.
Pick the new format
Choose JPG for photos, PNG when you need transparency or sharp text, or WebP for the smallest files. Set the quality for JPG and WebP.
Download the converted image
Press “Convert Image”. The image downloads in the new format, with the matching file extension.
Example: Example: a 1.8 MB PNG screenshot converted to JPG at quality 85 becomes about 220 KB — the same picture, a much smaller file.
About Convert Image
Different jobs need different image formats: JPG for photos, PNG for transparency and sharp screenshots, WebP for the smallest files on the web. ImageTools converts your images right in your browser — pick the format, set the quality, and download. The pixels never change, only the file format does, so the picture looks the same in its new format.
Converting to JPG makes photos much smaller; converting to PNG keeps every pixel exactly, including transparency. WebP gives the best of both for modern browsers. There is no upload, so your pictures never leave your device, and there is no watermark, no limit and no account. Everything is free, and it works on phones, tablets and computers.
Frequently asked questions
How do I convert JPG to PNG?
Choose your JPG image, select PNG as the output format, and press “Convert Image”. The PNG downloads immediately.
How do I convert PNG to JPG?
Choose your PNG, select JPG, and press “Convert Image”. Note: JPG has no transparency, so any transparent areas become white.
What is WebP, and why convert to it?
WebP is a modern image format that makes files much smaller than JPG or PNG at the same quality. Most websites and browsers support it now.
Will converting change the image quality?
PNG and WebP (lossless) keep every pixel. JPG uses lossy compression, so quality 85–95 looks the same while the file gets much smaller.
Is converting images free?
Yes. Converting images on ImageTools is 100% free. There is no paid plan, no limit and no watermark.
Do my images get uploaded?
No. The conversion happens entirely in your browser. Your images never leave your device and nothing is stored on any server.
