Most online tools require you to upload your sensitive documents to their servers. Shrinkify is different. We use WebAssembly (WASM) andWeb Workers to bring powerful desktop-grade processing directly to your browser. Your files stay on your machine, period.
Most online utility sites are wrappers around server-side scripts that collect your data. Shrinkify was built on the belief that **privacy shouldn't be a premium feature.** By leveraging modern browser capabilities, we've removed the need for data transfers entirely. This results in a tool that is not only faster but inherently more secure for everyone—from corporate professionals to students.
Since zero data is sent to a server, Shrinkify is ideal for legal, medical, or corporate documents that governed by strict privacy regulations.
By using WebAssembly, we achieve near-native execution speeds. Experience zero-lag compression that outperforms traditional server-side tools.
Yes! Shrinkify is completely free to use with no hidden subscriptions, limits, or watermarks. We believe professional privacy tools should be accessible to everyone.
We support all major formats including JPG, PNG, WebP, AVIF for images; MP3, WAV, FLAC, AAC for audio; and full PDF document support.
Only to load the page initially! Once opened, or if installed as a PWA, all tools work entirely offline because all the logic is stored in your browser.
