🔄 Image Convert
Change an image's format instantly in your browser — JPG, PNG, WebP, AVIF, GIF. Nothing is uploaded.
Frequently Asked Questions
Is my image uploaded to a server?
No. All conversion happens entirely in your browser using WebAssembly (libvips). Your file never leaves your device.
Which image formats are supported?
JPG/JPEG, PNG, WebP, AVIF, and GIF. You can convert between any of these formats.
Does image quality change during conversion?
You control quality with the slider (1–100). Lossless formats like PNG preserve full quality regardless of the setting.
Is there a file size limit?
No server-side limit. Very large files (100 MB+) may be slow depending on your device CPU.
Can I convert multiple images at once?
Currently one image per conversion. Drop a new file after downloading to convert another.
Is the tool free?
Yes, completely free. No account, no sign-up required.
Why is WebP or AVIF recommended?
WebP and AVIF offer significantly smaller file sizes than JPG or PNG with similar visual quality — ideal for web use.
