Image Format Converter
Convert any image between JPG, PNG and WebP formats. Conversion runs entirely in your browser using the Canvas API — no upload required.
How to Use the Image Format Converter
- Click "Select an Image" and choose the file you want to convert.
- Pick your target format: JPEG, PNG or WebP.
- For JPEG or WebP, adjust the quality slider if you want smaller or higher-fidelity output.
- Click "Convert" to see the result, then "Download Result" to save it with the right file extension.
Why Use This Tool?
Is my image uploaded anywhere during conversion?
No. The entire conversion happens locally in your browser: your image is decoded into a canvas element and re-encoded into the new format using built-in browser APIs. Nothing is ever sent to a server, so your photos and documents stay completely private.
What's the difference between JPG, PNG and WebP?
JPEG is best for photos where small file size matters more than perfect transparency support. PNG supports full transparency and lossless quality but produces larger files. WebP is a modern format that typically offers the smallest file size for a given quality level and supports transparency, though very old software may not open it.
Why is there no quality slider for PNG?
PNG is a lossless format — it doesn't use a quality setting the way JPEG and WebP do. Its file size depends only on the image content and compression algorithm, not an adjustable quality level.
Will converting to JPEG lose transparency?
Yes — JPEG doesn't support transparent pixels, so any transparent areas in your original image will be filled with white after conversion. If you need to keep transparency, convert to PNG or WebP instead.
