Resize Image Online — Exact Pixels or %

Resize Image — how it works

Resize photos by width, height or percentage in your browser. Keep aspect ratio, batch resize, no quality loss guesswork. Private and free.

Why FileZap is different

• Truly private. Unlike most online tools that upload your files to a server, FileZap processes everything inside your browser. Your files never leave your device.
• Instant. No upload/download round-trip and no processing queue — results appear the moment you drop a file.
• No catch. No sign-up, no email, no watermark, no daily limit.

FAQ

Can I keep the aspect ratio?

Yes — enter one dimension or a percentage and FileZap scales the other side automatically.

Does resizing reduce quality?

Making an image smaller is clean; enlarging beyond the original pixels will look soft, as with any tool.

Is it free with no limit?

Yes. Resize as many images as you like, free, in your browser.
