Entradas ja-comprimidas mudam o quadro. Fotos salvas como JPG, video salvo como MP4, audio salvo como MP3 e a maioria dos PDFs ja foram comprimidos no estilo DEFLATE quando foram escritos, entao envolve-los dentro de um ZIP ganha aproximadamente zero a cinco por cento - as vezes o arquivo fica ligeiramente maior por causa do overhead de empacotamento por entrada. Se seu objetivo e a menor entrega possivel, reduza a midia primeiro com um compressor de imagem ou video e entao agrupe os arquivos otimizados juntos.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
