This image converter uses the browser's Canvas API to convert and compress images entirely on your device. It supports JPEG, PNG, WebP, GIF, BMP, AVIF, and TIFF as input, and outputs JPEG, PNG, or WebP. You can process multiple images at once, adjust compression quality for JPEG and WebP output, and optionally resize images by maximum width while maintaining the original aspect ratio.
Input: JPEG, PNG, WebP, GIF, BMP, TIFF, AVIF, and HEIC. Output: JPEG, PNG, or WebP.
No. All conversion happens in your browser using the Canvas API. Your images never leave your device.
WebP gives the best compression for web use — typically 25–35% smaller than JPEG at the same visual quality, with transparency support. JPEG is best for photos; PNG for graphics that need pixel-perfect precision or transparency.
No. PNG uses lossless compression — the quality slider does not apply. To reduce PNG file size, convert to JPEG or WebP instead.
Yes. Drop or select multiple files. Each is processed separately with its own download button, and a "Download all" button appears for batch downloading.
For JPEG and WebP, it controls the trade-off between file size and visual quality. 80 is a good default — smaller than 100 but visually indistinguishable for most images.
Yes. Once the page has loaded, all conversion runs locally with no internet connection required.
Yes, completely free with no sign-up required and no usage limits.
