PDF tools

file4edit handles PDFs entirely inside the browser tab: cropping, reordering, rotating, merging, splitting, shrinking, watermarking, numbering, reading metadata and extracting text, plus conversion between PDFs and images in both directions. Most of these tools copy page objects rather than re-rendering them, so text stays selectable and images keep the exact bytes they arrived with. Nothing is uploaded, because there is no server to upload a document to.

How it works

  1. Pick the operation Choose the tool that matches what the document needs — the page groups them by whether they change the pages, convert them, draw on them, or only read them.
  2. Open your PDF Drop the file onto the tool. It is read from disk into the tab and opened with pdf.js; no copy is sent anywhere.
  3. Make the change Every tool previews the result on a rendered page before it writes anything, so what you see is what the file will contain.
  4. Save it The new document is written with pdf-lib in the tab and handed to you as a download. Several outputs arrive as one zip.

Questions

Can I edit a PDF without uploading it?
Yes. file4edit opens PDFs with pdf.js and writes them with pdf-lib, both running as JavaScript inside your browser tab, so the document is never transmitted. You can confirm it by opening the network panel while you work, or by disconnecting from the internet and continuing.
Does editing a PDF here reduce its quality?
Not for most operations. Cropping, reordering, rotating, merging and splitting copy page objects from one document into another, so text stays selectable, fonts stay embedded and images keep their original encoding. Only the PDF to images tool rasterises, because turning a page into pixels is what it is for.
Does cropping a PDF delete the content outside the crop?
No. Cropping sets the page CropBox, which is the region a reader displays, while the MediaBox and the content outside it remain in the file and can be recovered. That is correct for layout and wrong for secrecy — to remove something permanently, redact it or export the pages as images and rebuild the document.
Is there a file size limit?
Only your own machine. There is no service tier and no upload, so the limit is how much memory the browser will give the tab. Very large documents are slower to render page previews but are written the same way.
