Frequently Asked Questions

Find answers to your questions

Are images sent to a server?
No. All image processing happens 100% in your browser. WebAssembly-based codecs (MozJPEG, OxiPNG, libwebp, libavif) run locally, so images are never sent to or stored on a server.
How does the quality compare to TinyPNG?
We use the same MozJPEG and OxiPNG codecs, so compression quality is on par with TinyPNG. The difference is that processing happens in your browser instead of a server.
What is the AVIF format?
AVIF is a next-generation image format that achieves 30-50% smaller file sizes than JPEG/WebP. It's supported by modern browsers including Chrome, Firefox, and Safari.
Can I compress multiple images at once?
Yes, you can drag & drop multiple images simultaneously or select multiple files at once. All images are compressed with the same settings.
Is there a file size limit?
Since processing happens in your browser, there's no server-imposed limit. However, very large images (over 50MB) may take longer depending on your device's memory.
