Process many PDFs at once

A folder of invoices, scanned forms or course handouts often needs the same treatment for every file: make them small enough to email or upload, pull out the first page of each, turn them into images for a presentation, or collect their text. Doing that file by file is slow. This page takes up to 50 PDFs (500 MB together), applies one operation to each, and hands back either a ZIP with one result per file or a single merged PDF.

Operations: Compress keeps text, links and forms and re-encodes only the images inside (light, recommended or strong), using the same engine as Compress PDF; a file that is already compact comes back unchanged instead of growing. Extract pages takes the same range from every file, such as "1" for cover pages or "1-3, last", and simply skips pages that a shorter file does not have. Convert to images renders every page to JPG or PNG at 72, 150 or 300 dpi, one folder per PDF inside the ZIP. Convert to text writes a .txt file per PDF with the text in reading order. Rename only copies the files with new names.

For compress, extract and rename you can choose one merged PDF instead of a ZIP: the results are joined in the order of the list, which you can rearrange with the arrows, by dragging or with the arrow keys. Names follow a pattern with {name}, {n}, {n:3} and {date}, and duplicates get a number, so "invoice-{n:3}" gives invoice-001.pdf, invoice-002.pdf and so on.

Files are handled one after another, each with its own progress and result line. A password-protected or damaged PDF is marked with the reason and the batch continues; unlock or repair that file separately and run it again. Scanned PDFs have no text layer, so convert-to-text returns empty pages for them: run OCR PDF first.
