I built 250+ free browser tools (no signup, no watermark) — here's the full list

Tools Hub — Wed, 15 Jul 2026 16:29:16 +0000

Like a lot of developers, I got tired of hitting a paywall or a "create a free account to download" screen every time I needed to compress an image, format some JSON, or merge a couple of PDFs. So over the last while I built Tools Hub — a collection of 250+ small, single-purpose web tools. Most of them run client-side in your browser, which means your file or text usually never leaves your machine, there's nothing to install, and there's no queue.

No signup, no watermark on the output, no "3 free uses then upgrade." I'm sharing the categorized list below because I keep sending people individual links anyway — figured the full index might be useful to someone here. Everything below is a real, working link.

PDF tools

Merge PDF — combine several PDFs into one file, in order
Split PDF — pull out pages or break a PDF into parts
Compress PDF — shrink a bloated PDF for email/upload limits

That's a slice of the catalog — the full set is at freeseosmasher.com. If you'd rather have the same tools on your phone, there's a free Android app too: Tools Hub on Google Play. Happy to hear which tools are missing — I add ones people actually ask for.
