Image Format Converter — PNG, JPG, WebP

Drop image here or click to upload
Supports PNG, JPG, JPEG, WebP, GIF, BMP

Our Image Format Converter lets you change image file types in seconds — right in your browser. Whether you need to turn a PNG into a compressed JPG for web publishing, or convert a JPG to WebP for better compression on your website, this tool handles it all without uploading your files anywhere.

The converter supports PNG, JPG/JPEG, and WebP as both input and output. Drag and drop your image, pick the target format, adjust quality if needed, and download the converted file. It's that simple.

Why use WebP? WebP typically achieves 25-35% smaller file sizes than JPG at the same visual quality — making it ideal for website images and email attachments that need to load fast.

Since everything runs client-side, there are no file size limits, no upload queues, and zero privacy concerns. Your images stay on your device the entire time.

Ofte stillede spørgsmål

Is my image uploaded to a server?
No. Everything happens entirely in your browser using the Canvas API. Your original file never leaves your device — no uploads, no tracking, no waiting.
Which image formats can I convert between?
You can convert PNG, JPG/JPEG, and WebP into any of those three formats. GIF and BMP files will be converted to PNG or JPG output.
What is the best quality setting?
For JPG and WebP, quality 90-95 is visually near-identical to the original but significantly smaller. Quality 100 means no compression (large file). PNG is lossless — quality slider does not affect PNG output.
Will conversion change my image dimensions?
No. The converter preserves the original width and height exactly. Only the encoding format and optional quality change.
