How does image compression work?
Convertly compresses images directly in your browser using the Canvas API. It reduces file size by adjusting quality encoding — no file is ever sent to a server.
What image formats can I compress?
JPG, PNG, and WebP are all supported. For photos, JPG gives the best compression. For graphics with transparency, use PNG or WebP.
Is it safe to compress my photos here?
Completely safe. Your images are compressed locally in your browser — no upload, no server, no data ever leaves your device.
