The idea

Almost every free tool for compressing an image or merging a PDF works the same way. You upload the file, a server does the work, and you download the result. It is a reasonable design, and it has two costs that people rarely think about: you wait for the upload, and a copy of your file sits on somebody else's machine.

Modern browsers no longer need that arrangement. They can decode images, re-encode them, read PDF structure and write new documents — all locally. Every tool here is built that way. There is no upload step, no processing queue, and no server that ever sees your file.

What that changes in practice

• No file size limits. There is no bandwidth bill to control, so nothing is capped at 5 MB or gated behind an account. The only ceiling is your device's memory.
• No waiting. Work starts the instant you drop a file, rather than after it finishes travelling.
• Nothing to leak. Contracts, identity documents, medical scans, API keys in a JSON file — none of it is transmitted, so none of it can be breached, retained or subpoenaed.
• No watermarks, no sign-up. There is no premium tier to push you toward.

The honest limitations

Local processing is not free of trade-offs, and it would be dishonest to pretend otherwise.

• Image compression uses the browser's own encoder. It is good, but a dedicated tool running a specialised encoder can squeeze out a little more at the same visual quality.
• Large jobs depend on your hardware. A hundred high-resolution photos will process comfortably on a laptop and may struggle on an older phone.
• Some formats are not supported because browsers cannot decode them natively — HEIC being the notable one.
• PDF tools cannot open password-protected files, since the password is not ours to bypass.

How the site is paid for

Advertising, through Google AdSense. That is the whole model. There is no premium plan, no data collection to sell, and no upsell — partly on principle, and partly because a tool that never sees your files has no data to monetise even if it wanted to.

The tools

Eleven at the moment, with more added as they prove useful.

Feedback

If a tool produces a wrong result, breaks on a particular file, or is missing something obvious, that is worth knowing about. The contact page explains how to get in touch and what to include so the problem can actually be reproduced.
