Frequently Asked Questions
About Image Converter
Confileo's Image Converter tool converts images between JPG, PNG and WebP. It works in any browser, free to start and without signup, and a file sent to our server is deleted automatically after processing.
Converting between image formats is almost always about fixing an incompatibility rather than improving the picture: an upload form that rejects everything but JPG, a website that will not display HEIC from an iPhone, a design tool that needs PNG for its transparency, or a page that loads too slowly because its images are twice the size they need to be.
You upload the image, choose the target format, and download the converted file. JPG, PNG and WebP are supported, and nothing is installed.
Choosing the right target is simple once you know what each format is for. JPG suits photographs and produces small files, but it cannot hold transparency and loses a little detail every time it is saved. PNG keeps transparency and stays pixel-exact, which makes it right for logos, screenshots and anything with sharp edges or text, at the cost of a larger file. WebP does both jobs at a smaller size and is supported by every current browser, which makes it the better default for images on a website — though some older desktop software still will not open it.
One rule worth remembering: converting JPG to PNG does not restore quality. The detail a JPG discarded is gone, and the PNG simply preserves the flawed version at a larger file size. Conversion changes the container, not the contents. Always convert from the best original you still have rather than from a copy that has already been through compression.
Converting a transparent PNG to JPG has the opposite problem: the transparency has to become a colour, and that colour is white. If the image will sit on a dark background, compose it onto that background before converting rather than after.
Your file is processed and then deleted, and the original on your device is unchanged.

Image Converter — Frequently asked questions
Which format should I choose?
JPG for photographs and small files, PNG for logos, screenshots and anything needing transparency, WebP for websites where you want both.
Does converting JPG to PNG restore quality?
No. Detail a JPG discarded is gone. Conversion changes the container, not the contents, so always start from the best original you have.
What happens to transparency when I convert PNG to JPG?
JPG has no transparency, so cleared areas become white. Compose the image onto its final background before converting.
Is WebP safe to use?
Every current browser supports it, though some older desktop software still will not open it. For images on a website it is the better default.
Does the tool change the image size?
No. Only the format changes. Use Image Resize to change pixel dimensions.
Is my original file modified?
No. You download a converted copy and the original stays on your device.
Is this tool really free?
You can try it free: 50 credits without an account and 300 with a free account, renewed on the 1st of every month. Every tool uses credits — file tools 3 per file and the heavy ones 12. No watermark, no credit card. Beyond the monthly credits, Pro gives open use with no credits to count, or you can buy a credit pack.
Do I need to create an account?
No. You can use the tool straight away without signing up or logging in.
Are my files safe and private?
Yes. A file sent to our servers travels over an encrypted HTTPS connection and is deleted automatically after processing; tools that work in your browser never upload it. We don't open, read or sell your files.
Does it work on my phone?
Yes. The tool runs in any modern browser, so it works the same on desktop, tablet and mobile with nothing to install.
