The most common lie in the PDF world is the word "free." The tool is free the way a toll road is free the first time — until you hit the paywall at 2 MB, or the watermark, or the "your file has been uploaded to our servers, processing may take up to 1 hour" queue.
I built a set of PDF tools on toolfyra.com that work differently: everything runs in your browser, files never leave your machine, and there's no signup between you and the output. This post covers the six jobs they handle, when each is the right call, and — honestly — when you should use something else.
1. Merge PDFs
Merge PDF — Drop in multiple files, drag to reorder, merge into one. This is the tool I use most myself: statement + receipt + invoice into a single expense file. The merging happens locally in your browser using PDF libraries compiled to WebAssembly, which is why there's no file-size "free tier" — your machine is doing the work, not a shared server.
2. Convert PDF pages to images
PDF to JPG — Export pages as images, useful for slides you want to drop into a deck or doc, or for sharing a single page in a chat without sending the whole document. One honest caveat: converting to JPG means you lose text selection and searchability. If you need the PDF to stay a PDF, don't convert it — that's a different tool.
3. PDF to PowerPoint
PDF to PPT — The reverse-rescue operation: someone sent you a PDF of a deck, the original .pptx is gone, and you're expected to "just make a small edit." This gets you an editable-ish PowerPoint back. Set expectations correctly: complex layouts won't survive pixel-perfect, so do a quick visual pass on each slide before you present anything.
4. Fill PDF forms
PDF Form Filler — The eternal government-form problem: the PDF has fields, your viewer flattens them, and the instructions say "print, fill by hand, scan back." This tool lets you type into the fields and download the filled result. It has quietly saved me more hours than any other tool I've built.
5. Add page numbers
PDF Page Numbers — Add page numbers with position and format options. Trivial in Word, weirdly absent from most free PDF flows. Attachments for legal, academic and tender submissions routinely get rejected for missing page numbers, so this is a small tool with outsized "unblock your afternoon" energy.
6. Extract text with OCR
OCR Text Extractor — When the PDF is a scan (image, not text), this runs OCR locally and gives you the text layer. Quality depends heavily on scan quality — a clean 300 DPI scan extracts beautifully, a phone photo of a receipt at midnight extracts like a phone photo of a receipt at midnight. Garbage in, slightly organized garbage out.
Why "no upload" is the whole point
A surprising number of "free" PDF tools send your file to their servers for processing. For a public menu that's fine. For a contract, an ID scan, a payslip, or a medical report, it's a decision you should make consciously. I wrote a longer piece about what free file converters actually do with your files — the short version: zero-retention is an architecture property, not a checkbox, and the only way to guarantee a file never leaks is for it to never leave your device. That's the design principle behind this entire set.
When to use something else
Big, complex, interactive PDF work — live form design, redaction workflows, digital signatures with certificate infrastructure — belongs in professional software. These six tools cover the high-frequency, low-complexity jobs that make up maybe 80% of everyday PDF interactions, and they do it without an account or an upload.
Everything lives under the PDF tools hub, so one bookmark covers the set. If you've ever printed a PDF just to fill it by hand, start with the form filler.
Disclosure: toolfyra.com is my own project. This post is part of a series about building it — I write about the architecture decisions, the data, and the occasional embarrassing bug.
