Frequently asked questions
Does MiniFiles upload my images to a server?
No. All image compression happens locally inside your browser using JavaScript and WebAssembly. Your images are never transmitted to any external server.
Which image formats are supported?
MiniFiles compresses PNG, JPEG, WebP (including animated WebP) and GIF. Anyone can convert the output to WebP for free; converting to JPEG or PNG is a Pro feature.
Will compression reduce image quality?
MiniFiles uses intelligent lossy compression that preserves visual quality while dramatically reducing file size. For most use cases, the difference is invisible to the eye.
Can I compress multiple images at once?
Yes — drop in as many as you like and they are compressed as a batch. Without an account you can compress 10 files a day; a free account removes the daily limit. MiniFiles sets no file size limit on any plan.
Is this better than TinyPNG?
TinyPNG uploads your images to its servers for processing. MiniFiles compresses them inside your browser, so the image files never leave your device.
