A PDF studio that runs in the browser
One workspace, separate jobs
The PDF studio is the place for finished PDF files: merge and reorder pages, split a packet, compress a scan, turn images into a PDF, export pages as pictures, or burn a permanent black box into a marked page. Each of those jobs has its own address so you can open the right one directly. Merge starts in page organizing with a single exported PDF. Split starts on a fixed one-page range. Compress starts on the quality slider. Redact starts on the black-box tool. The shared sidebar lets you change jobs, but the page you opened already selected the one named in the title.
Nothing in this studio uploads the PDF to a NexTool server. The file stays in the tab. Password-protected files have to be unlocked before most jobs will accept them. A huge file can fail when the browser runs out of memory, which you will see as an error on the page rather than a finished download. Keep the original. The export is a new file, and closing the tab drops it. If you need a searchable Word document, this studio is the wrong room. Use Word tools for .docx files, and use OCR only when you actually need text pulled off a picture.
What is preserved, and what is redrawn
Merge and split copy pages. They do not retype the text and they do not recompress the images inside those pages, so a merged file can be larger than either source. Compress is the opposite: it redraws pages as JPEG pictures at the quality you set, which is how the file gets smaller and also how sharp text can turn soft. Redact is destructive on purpose. The black box is burned in, and the marked page is no longer a layer of selectable text underneath a rectangle you could delete later. Exporting pages to images is a picture of each page, useful for a slide or a preview, not a way to get the words back as a document.
Before you rely on an export, open it. Count the pages. Read a sentence that mattered. If you redacted, try to select the text under the box. If you can still copy the number, the redact did not land and you should not send that file. The longer essays in the guides walk through merge order, the difference between a local tool and an upload site, and why compress is a quality trade rather than a free shrink button. Use those when you are deciding. Use this studio when you are ready to run the job on a file you are allowed to modify.
A normal session
Add the file from the button or drop it on the page. Wait until the page thumbnails appear before you change the order or draw a box. The thumbnails are the browser drawing the PDF, not a copy stored on nextool.org. If an import error appears, the usual causes are a password, a file that is not a PDF, or a PDF the tab cannot hold. Unlock, pick a real PDF, or try a shorter file. Then choose the job in the sidebar only if the address you opened is not already the one you wanted. Export when the preview matches the story you mean to send: appendix last, one page per file, or a black box that actually covers the number.
Download the result and open it outside the tool, in a normal PDF reader if you have one. The in-page preview is a guide. The file you attach to mail is the one that matters. If you need pictures of the pages rather than a PDF, use PDF to images. If you are starting from photos and want a PDF, use images to PDF. Those are different directions. Mixing them up is how people export a ZIP of JPEGs when they meant to send one document, or the other way around.
