About EazyTools
Why nothing gets uploaded
Most online PDF and image tools work by sending your file to their server. That includes contracts, ID scans, medical records and internal company documents — the files you would least like a stranger to hold. Where that copy is stored, when it is deleted and who can open it are not things you can verify.
EazyTools runs the other way round. Instead of sending the file to an engine, it brings the engine to the file: the processing code is compiled to WebAssembly and downloaded into your browser. Your file stays on your device from beginning to end, and our servers never receive, see or store it. You can confirm this by opening a tool, disconnecting from the internet, and using it anyway.
What you can do here
For PDFs: compress, merge and extract pages. Compression is what most people arrive for — mail attachment limits and government or school upload forms have hard ceilings — so there are dedicated pages for the sizes those forms usually demand: 100KB, 200KB, 500KB, 1MB and 2MB.
For images: convert between JPG, PNG and WebP, reduce file size, combine several images into a single PDF, and cut the background out of a photo to produce a transparent PNG. Background removal also runs on your device, using an open-source model — photos are not uploaded either.
What it is built on
PDF compression uses Ghostscript, the engine the print and publishing industry has relied on for more than thirty years, compiled to WebAssembly. Merging and page extraction use pdf-lib, image conversion and compression use the browser's built-in Canvas, and background removal uses an ISNet-family open-source model.
None of this is a homegrown algorithm — it is established open source moved into the browser, so output quality and compatibility match the desktop tools you would otherwise use. Each tool page lists the libraries and licences it depends on.
Frequently asked questions
- Are you sure nothing is uploaded?
- Yes — and you can check. Open your browser's developer tools, watch the Network tab while you work, and you will see no request carrying your file. Opening a tool and then disconnecting from the internet also leaves it fully working.
- Is there a file size limit?
- No server limit. Processing does use your device's memory, though, so a very large file can exhaust what the browser has available. On a desktop machine, files of a few hundred MB are generally fine.
- Do I need an account or a subscription?
- Neither. There is no sign-up, no payment, no usage cap and no watermark. Not processing files on a server keeps running costs low, and the ads on the page cover them.
- Does it work on a phone?
- It does, but phones have less memory available than desktops, so large files can fail. For big documents, a computer is the more reliable option.
