What this is

A collection of small tools, each doing a single job. There is no account, no upload queue and no step between opening a page and getting your result — you land on the tool, do the thing, and leave.

Every tool is written for this site. Nothing here is an embed of somebody else’s service or a listing that sends you elsewhere.

Why the preset pages exist

People rarely arrive wanting to “compress an image.” They arrive because a form refuses anything over 100 KB, or because a visa application demands 35 × 45 mm, or because a US visa photo has to be exactly 600 × 600. The requirement comes first and the tool second.

So each of those specifications gets its own page, and each page says where the requirement comes from and what to realistically expect at that size — not just a number in a box. If a page has nothing to say beyond the number, it should not exist, and we would rather have fewer of them than pad the site with variations.

Where the work happens

Most of these tools never send your file anywhere. The browser reads the image straight from your disk, draws it onto a canvas, and assembles the result locally — the file simply never travels.

That will not be true of everything forever; some things need a server to be possible at all. Rather than make a promise that quietly expires, every tool page states where that particular tool runs, right next to its title. The privacy page explains what each of those two badges means.

How it is built

The pages are pre-rendered static files. There is no database, no login, no cookie, no analytics script and no ad network — partly because none of it is needed, and partly because every one of those would be something new to explain on the privacy page.

Tool descriptions and presets live in the source code rather than in a CMS, which means every change to them goes through review and version control like any other change.

What this site is not

It is not a directory of other people’s tools, and there are no user submissions, comments or votes to moderate.

You will also not find “best tools for X” rankings or head-to-head comparison pages here. A site that ranks its own tools and then puts itself first has told you nothing, and we would rather leave that traffic on the table than publish a verdict nobody should trust.

Contact

A tool that gives a wrong result, a page that breaks on your device, or a specification you keep needing and cannot find here — all of it is worth an email: [email protected].

Bug reports are more useful with the browser and device you were on, and what you expected to happen. Please describe the file rather than attaching it — for tools that run in your browser, we never receive it and cannot reproduce anything from our side without your help.
