Image Converter – Free Online Tool
Convert images between JPG, PNG, and WebP locally with preview, quality control, background fill, and file size comparison.
Free Image Converter for JPG, PNG, and WebP
The Image Converter helps you switch image formats quickly without uploading files. Convert JPG photos to WebP for smaller websites, PNG graphics to JPG for compatibility, or WebP images to PNG or JPG when an app does not accept WebP.
Which Image Format Should You Choose?
Use JPG for photos and broad compatibility, PNG for transparency and crisp graphics, and WebP for modern web images with smaller file sizes. This tool shows the converted size so you can decide whether the new format is actually better for your use case.
Smart Pairings With Other Image Tools
Use the AI Background Remover first when you need a transparent cutout, then convert the result with the Image Converter. Use the SVG to PNG Converter when starting from vector graphics, or the YouTube Thumbnail Downloader when collecting public thumbnail references.
Private Conversion for Personal Photos
Images can contain personal faces, locations, products, or client work. ToolsMint processes the conversion in your browser using canvas APIs, so your original image is not uploaded to a conversion server.

Frequently Asked Questions
Everything you need to know about the Image Converter.
Is this image converter free?
Yes. It is free with no signup, watermark, or upload requirement.
Which formats can I convert to?
The tool exports JPG, PNG, and WebP. It can load most image types supported by your browser.
Does the image leave my device?
No. Conversion happens locally in your browser.
Why does PNG quality not change?
PNG is lossless in the browser export path, so the quality slider applies to JPG and WebP, not PNG.
What happens to transparency when converting to JPG?
JPG does not support transparency, so the tool lets you choose a background color to fill transparent areas.
Is WebP always smaller?
Often, but not always. The tool compares original and converted file sizes so you can choose the best result.
