About ToolCaravan
ToolCaravan is a small collection of single-purpose tools, built and maintained by one person. This page explains who that is, why the site exists, and what it deliberately does not do.
Who writes and maintains this site
My name is Nina Hart. I build every tool on this site myself, I write the guides underneath them, and I answer every message that arrives through the contact page. There is no team and no agency behind this — if something is broken, I am the one who fixes it.
Why this site exists
I do design and image work, most of it for small online sellers. That means I spend my days on two things that never appear in a portfolio: making product images look right, and getting those images past the rules of whatever marketplace they are going onto.
The designing part is the fun part. The rest is assembly line work — resizing a set of listing photos to a pixel size a specific platform demands, squeezing files under an upload limit, converting to a format a form will actually accept, putting a product onto a clean white background because the marketplace refuses anything else.
None of that is hard. It is just constant, and it is exactly the kind of work that gets interrupted by a rejection notice at the worst moment. I have had a whole batch of photos refused because they were twenty pixels short of the minimum. I have had a supplier send product shots at eight megabytes each when the upload form accepted two.
Why not just use one of the existing sites
I tried. The problem is not that the tools do not exist — it is what most of them ask for in return. They want an account before they will process a single file. They cap you at three images and then ask for a subscription. They stamp a watermark on the output. Or they quietly upload your client's product photos to a server you know nothing about, which is a genuinely bad idea when those photos are somebody else's unreleased product line.
So I started building the small utilities I actually needed, in the shape I wanted to use them: one page each, one job each, no account, and running on your own device wherever that is technically possible.
How the tools are built
- One page, one job. No dashboards, no workspaces, no "projects". You arrive with a specific problem and you leave without one.
- Your files stay on your device wherever the browser can do the work itself. Resizing an image does not require a server, and sending your files to one would be worse on every axis — slower, less private, and dependent on somebody else's uptime.
- When a server really is required, the page says so before you use it, names the service doing the processing, and tells you what happens to the file afterwards. No exceptions, no small print.
- Free means free. No trial, no file limit, no watermark, no "upgrade to export".
What this site does not do
Being clear about the limits seems more useful than pretending there are none:
- There is no account system, and there never will be. Nothing here needs to know who you are.
- Nothing is stored. Close the tab and the work is gone — which also means there is no history to recover, so download what you need before you leave.
- These are small utilities, not a suite. If you need batch editing across hundreds of files with presets and versioning, a desktop application will serve you better.
- Nothing here will make a bad photo good. If the source image is too small or badly lit, no amount of resizing fixes it.
How this site is funded
Advertising. The tools are free, there is no paid tier, and display ads pay for the domain and the hosting. That is the entire business model, and it is the reason there is no login wall anywhere on this site.
Corrections and requests
If a tool gets something wrong, I want to know — especially if it produces a file a marketplace rejects, because that is the exact failure this site exists to prevent. And if there is a task you keep doing by hand and wish had a one-page tool, say so. Several of the tools here started as somebody else's complaint.
