HOW IT WORKS
From one format to another in seconds
Converting an image means re-encoding its pixels into a different file format. This tool does that on the HTML canvas in your browser, so your images never touch a server and the new file downloads straight away.
Drop in your images
Add one image or a batch of JPG, PNG and WebP files. Each one is read and decoded locally on your device.
Choose the output format
Pick WebP, JPG or PNG. Set a quality for the lossy formats, and resize the longest side if you want smaller dimensions too.
Download the new files
See the new size next to the original, then download each converted image. EXIF and location data are stripped on the way out.
WHAT THIS TOOL DOES
A full image converter, with nothing uploaded
Everything runs on the HTML canvas in your browser, so it is fast, private and works offline once the page has loaded.
JPG, PNG and WebP
Convert freely between the three formats the web runs on, in any direction: JPG to WebP, PNG to WebP, WebP to JPG and more.
Modern WebP output
WebP is usually 25 to 35 percent smaller than JPG or PNG at the same quality, and every current browser supports it.
Quality you control
Set the quality for WebP and JPG output, with the new file size shown next to the original so you can see the trade-off.
Resize while you convert
Cap the longest side to 1920px or any width you choose, to change format and dimensions in a single pass.
Many images at once
Drop a whole folder of images in together. Each is converted to the same format and downloaded one by one.
Nothing leaves your device
No upload, no account, no queue. Your images are processed locally and re-encoding strips EXIF and GPS metadata.
IN-BROWSER VS UPLOAD TOOLS
Convert images without handing them to a server
Most online converters upload your files, process them in the cloud and send them back. This one does the work on your machine, so it is private by default and there is no size queue or waiting.

FAQ
Image converter questions
Is this image converter free?
Yes. It is free with no signup, and it runs entirely in your browser, so your images are never uploaded to a server. To audit image formats and sizes across a whole site, download the free SiteAuditLint desktop app.
Which formats can I convert between?
You can convert JPG, PNG and WebP images to JPG, PNG or WebP. Drop in any of the three and choose the format you want out, including JPG to WebP and PNG to WebP.
Are my images uploaded anywhere?
No. Conversion happens locally in your browser using the HTML canvas, so your images never leave your device. Nothing is sent to a server and nothing is stored.
Should I convert images to WebP?
WebP is usually 25 to 35 percent smaller than JPG or PNG at the same visual quality, and every current browser supports it, so it is a strong default for the web unless you need compatibility with very old software.
Does converting to JPG lose transparency?
Yes. JPG does not support transparency, so a transparent PNG converted to JPG is placed on a white background. Convert to PNG or WebP if you need to keep transparency.
Does this keep image quality?
PNG output is lossless. JPG and WebP are lossy, and a quality control lets you balance file size against sharpness, with the before and after size shown for every image.
