Compress Images with no file limit — 100% in Your Browser
zipo.pics processes files locally so your photos never leave your device. See exactly what you get below.
Most "free" compressors upload your photo to their server, compress it there, and hope you do not read the fine print. zipo.pics is built the opposite way: the work happens on your device and the image never travels.

Local processing is the same across every zipo.pics tool — your files never touch a server.
How local processing actually works
The compression engine is Rust compiled to WebAssembly and shipped inside the page. Once loaded, it runs entirely in your browser — there is no server round-trip, no upload queue, no copy stored anywhere. That is why the tool also works offline after the first load.
What you get
No account to create, no credit balance to watch, no watermark stamped on your output. Your files never touch a server, so there is nothing to leak and nothing to subpoena. Local-first is not a feature here; it is the architecture.
FAQ
Are my images uploaded?
Never. All compression runs in your browser with Rust + WebAssembly; images never leave your device.
Do I need an account?
No account, no credits, no watermark — compression is free and unlimited.
Does it work offline?
Once loaded, compression runs fully offline because the engine lives in your browser.
Is my image uploaded to a server?
No. Every conversion runs inside your browser, on your own device, using Rust compiled to WebAssembly. The image bytes are never sent to zipo.pics or to any third party — which is also why the page keeps working offline after it has loaded once.
Is zipo.pics free? Is there a limit on how many images I can compress?
Standard compression is free and unlimited: no account, no image-count cap. Credits are only needed for optional extras such as AI enhancement, noise removal, watermark removal and HD export.
Which image formats can it compress?
PNG, JPG/JPEG, WebP, AVIF and GIF, and you can convert between them. Choose PNG to shrink a photo while keeping every pixel, WebP or AVIF for the smallest file at a given quality, and JPG when you need universal compatibility.
Will compressing my image reduce its quality?
You decide. Each result is shown next to the original before you download, so you can lower or raise the strength per image. Lossless mode re-encodes the same format without discarding data; stronger settings trade a little fine detail for a much smaller file.
