PDFs are everywhere, but editing them usually requires expensive software. Loopaloo handles the most common PDF tasks without Adobe Acrobat or any subscriptions. Merge documents before a filing deadline, split a 200-page manual into chapters, reorder pages that got scanned out of sequence, add a signature to a contract, or password-protect a sensitive report. The tools use client-side JavaScript libraries (pdf-lib, PDF.js) so your documents stay on your machine the entire time.
Think about what lives in PDF files: tax returns, medical records, signed contracts, bank statements, legal briefs. These are exactly the files you should never upload to a random website. Local processing also means there is no 10 MB or 50 MB upload limit - merge a stack of scanned documents totaling hundreds of megabytes without hitting a paywall or a progress bar.
Turn pictures into a PDF at the size on paper you choose. Set the resolution a pixel count prints at, pick the paper, and see every page size and the resolution it prints at before anything is written.
List every annotation a PDF carries, including the highlights, links and stamps that have no note attached, with the author, colour, page position and reply of each.
Shrink a PDF losslessly, resample its pictures, or rasterise it
Trim what a PDF page shows, with a real preview
Running heads and page numbers, placed where the page really is
Pull out a PDF's pictures as the files it holds
Join PDFs into one document, with a bookmark for each file
Drop pages from a PDF, or keep only the ones you choose
Rearrange a PDF by drag, keystroke, preset or typed order
Encrypt a PDF with AES-256, and check the result
Turn PDF pages, counting from the rotation they already carry
Draw, type or upload a signature and place it on the page a reader sees, at a width you can state in inches, on one page or every page. Transparent, so it does not hide the line you are signing on.
Split a PDF by page, by batch, or by range
Read a PDF's text in the order a person reads it
Impose pages for folding, with the order checked
Render PDF pages at a resolution you set in dpi
Stamp a mark where the page really is, anchored or tiled
