Different situations call for different image formats. JPEG is ideal for photographs with smooth color gradients and small file sizes. PNG excels at graphics, logos, and screenshots where you need transparency or lossless quality. WebP offers the best of both worlds with superior compression and modern browser support. Our free Image Format Converter lets you switch between all three instantly.
The quality slider gives you fine-grained control over the output. Lower the quality for smaller file sizes perfect for web use, or keep it high for print-quality results. The side-by-side preview and file size comparison help you find the optimal settings before downloading. No more guessing — you can see exactly what you are getting.
Everything runs locally in your browser using the Canvas API. Your images are never uploaded to any server, making this tool safe for sensitive or proprietary images. Whether you need to convert a batch of screenshots to WebP for your website, or turn a PNG logo into a JPEG for a presentation, this tool handles it in seconds.
Frequently Asked Questions
What is the difference between JPEG, PNG, and WebP?▾
JPEG uses lossy compression and is best for photographs. PNG uses lossless compression and supports transparency, ideal for graphics and logos. WebP supports both lossy and lossless compression with smaller file sizes than JPEG or PNG, and is supported by all modern browsers.
Does converting reduce image quality?▾
Converting to PNG is lossless and preserves all detail. Converting to JPEG or WebP with quality below 100% applies lossy compression, which may introduce minor artifacts. Use higher quality settings (80-100%) for minimal visible difference.
Why did my file get larger after converting?▾
Some format conversions increase file size. For example, converting a highly compressed JPEG to PNG will produce a larger file because PNG stores pixel data without lossy compression. The size comparison bar helps you see this before downloading.
Are my images uploaded to a server?▾
No. All image conversion happens entirely in your browser using the Canvas API. Your images are never uploaded, stored, or transmitted to any server.
What image formats can I upload?▾
You can upload any image format your browser supports, including JPEG, PNG, WebP, GIF, BMP, and SVG. The output can be saved as JPEG, PNG, or WebP.
