QuikLab's PDF toolkit is a set of common PDF operations — merge, split, compress, rotate, watermark, and convert to/from images — that all run locally in your browser. There's no upload step, no account, and no server involved.
No. Every operation runs in your browser using JavaScript (via the pdf-lib and pdf.js libraries). Your PDF and its contents never leave your device.
It re-encodes embedded images inside the PDF at a lower quality and removes unused objects, which shrinks image-heavy PDFs substantially. Text-only PDFs are already compact and may not shrink much further.
Yes. Add your files and drag them into the order you want before merging — the output follows that order.
Yes, both directions. Image to PDF places each JPG, PNG, or WebP you upload on its own page. PDF to image renders each page of a PDF as a downloadable PNG.
QuikLab's image compressor resizes and compresses JPG, PNG, WebP, SVG, and GIF files the same way — entirely in your browser.
