The toolkit at a glance
The PDF category covers the everyday document jobs that usually require desktop software or an upload to a stranger's server. You can combine files, break them apart, shrink them, convert to and from images, reorganize pages, and pull text out — 21 tools in total.
Each tool is single-purpose and focused, so the controls stay simple. You add your PDF, set the one or two options that matter, and download the result. There is no account gate and no watermark stamped onto your pages.
Because these are contracts, resumes, invoices, and other sensitive documents, the fact that everything runs on your device is the point. Your file is read into the browser, edited locally, and saved back — it never leaves your computer.
Convert between PDF and images
A large share of PDF work is really format conversion. QRix converts images into a PDF — for example turning a set of JPGs into a single document — and converts PDF pages the other way into image files such as PNG, which is handy for embedding a page into a slide or a web page.
The image-to-PDF direction assembles your pictures into ordered pages at the size you choose. The PDF-to-image direction renders each page faithfully using an in-browser PDF engine, so the output matches how the page actually looks, including fonts and layout.
These conversions are lossless in the sense that they do not phone home. The rendering happens with the same PDF technology browsers use to display documents, running locally in your tab.
Organize and edit pages
When a document is structurally wrong rather than mislabeled, the organizing tools fix it. Merge stitches several PDFs into one in the order you set. Split pulls a range of pages into a new file or breaks a document into pieces.
Reorder rearranges pages by dragging them into the sequence you want. Rotate fixes pages that were scanned sideways or upside down. Crop trims away margins or unwanted edges, and page-removal tools drop pages you do not need.
All of these rewrite the PDF's internal structure directly on your device using an in-browser PDF library, preserving the original text and vector content rather than flattening the page to an image. The result is a real, editable PDF, not a screenshot of one.
Read and extract
Sometimes you need the words, not the document. The PDF-to-text tool extracts the selectable text from a PDF so you can copy it into another program, and it works locally without sending the file anywhere.
For scanned documents — pages that are really images of text with no selectable characters — the OCR tool uses on-device optical character recognition to read the letters out of the picture. This runs as a WebAssembly module in your browser, so even a confidential scan stays private.
Extracted text is a starting point for search, editing, or repurposing content. Accuracy depends on the source: clean digital PDFs extract perfectly, while low-resolution or skewed scans are harder, as they would be for any OCR engine.
Everything stays on your device
The PDF tools are built on established in-browser document engines — one library for reading and rendering pages, another for editing and writing them, and a WebAssembly OCR engine for scans. None of them require a server round trip.
This matters most for exactly the files people are nervous about uploading: signed agreements, financial statements, medical records, and identity documents. With QRix there is no upload, so there is no remote copy and nothing to be retained or exposed.
If you want to confirm it, watch your browser's network activity while you run a PDF tool. The page and its engine load once; after that, your document is processed entirely in the tab, and the download is generated locally.
