Shrink your PDFs without losing quality. Free, no sign-up, 100% in your browser — your files are never uploaded.
Compressing a PDF reduces its size so you can email it, upload it to a form with a size cap, or store it using less space. Most “free” sites upload your document to a server; fetchio.io works the other way around: compression happens inside your browser, so the file never leaves your device. The tool re-encodes the PDF’s images —the heaviest part— and rewrites an optimized document, with no watermarks and no daily limits. Pick Balanced for everyday use or Smallest size when you need the file as light as possible to attach to an email.
Drag it to the area above or click to choose it. Nothing is uploaded.
Balanced for everyday use; smallest size for email.
Your compressed PDF is ready in seconds. Copy or download it.
No. fetchio.io compresses the PDF directly in your browser with WASM/JS. The file never leaves your device.
With “Balanced” the difference is imperceptible. “Smallest size” reduces more.
Since everything is local, the only limit is your device memory.
It depends on the document: PDFs with many images or scans shrink a lot (often 50–90%); text-only files drop little, because they’re already small.
fetchio.io never uploads your file, adds no watermarks, and doesn’t cap how many PDFs you compress per day. Everything is free and processed in your browser.
